AbstractThis laboratory course teaches fundamental concepts in computational science and machine learning based on matrix factorization. This method provides a powerful framework of numerical linear algebra that encompasses many important techniques, such as dimension reduction, clustering, combinatorial optimization and sparse coding.
ObjectiveStudents acquire the fundamental theoretical concepts related to a class of problems that can be solved by matrix factorization. Furthermore, they successfully develop solutions to application problems by following the paradigm of modeling - algorithm development - implementation - experimental validation.

This lab course has a strong focus on practical assignments. Students work in groups of two to three people, to develop solutions to three application problems:
1. Compression: Exploiting image statistics to compress an image with minimal perceptual loss.
2. Collaborative filtering: predicting a user interest, based on his own and other peoples ratings. The "Netflix prize" is one such example.
3. Inpainting: Filling in lost parts of an image based on its surroundings.

For each of these problems, students submit their solutions to an online evaluation and ranking system, and get feedback in terms of numerical accuracy and computational speed. In the final part of the course, students combine and extend one of their previous promising solutions, and write up their findings in an extended abstract in the style of a conference paper.

263-2300-00LHow To Write Fast Numerical Code Information
Prerequisite: Master student, solid C programming skills.
W6 credits3V + 2UM. Püschel
AbstractThis course introduces the student to the foundations and state-of-the-art techniques in developing high performance software for numerical functionality such as linear algebra and others. The focus is on optimizing for the memory hierarchy and for special instruction sets. Finally, the course will introduce the recent field of automatic performance tuning.
ObjectiveSoftware performance (i.e., runtime) arises through the interaction of algorithm, its implementation, and the microarchitecture the program is run on. The first goal of the course is to provide the student with an understanding of this interaction, and hence software performance, focusing on numerical or mathematical functionality. The second goal is to teach a general systematic strategy how to use this knowledge to write fast software for numerical problems. This strategy will be trained in a few homeworks and semester-long group projects.
ContentThe fast evolution and increasing complexity of computing platforms pose a major challenge for developers of high performance software for engineering, science, and consumer applications: it becomes increasingly harder to harness the available computing power. Straightforward implementations may lose as much as one or two orders of magnitude in performance. On the other hand, creating optimal implementations requires the developer to have an understanding of algorithms, capabilities and limitations of compilers, and the target platform's architecture and microarchitecture.

This interdisciplinary course introduces the student to the foundations and state-of-the-art techniques in high performance software development using important functionality such as linear algebra functionality, transforms, filters, and others as examples. The course will explain how to optimize for the memory hierarchy, take advantage of special instruction sets, and, if time permits, how to write multithreaded code for multicore platforms. Much of the material is based on state-of-the-art research.

Further, a general strategy for performance analysis and optimization is introduced that the students will apply in group projects that accompany the course. Finally, the course will introduce the students to the recent field of automatic performance tuning.

AbstractThe course covers advanced methods of statistical learning :
PAC learning and statistical learning theory;variational methods and optimization, e.g., maximum entropy techniques, information bottleneck, deterministic and simulated annealing; clustering for vectorial, histogram and relational data; model selection; graphical models.
ObjectiveThe course surveys recent methods of statistical learning. The fundamentals of machine learning as presented in the course "Introduction to Machine Learning" are expanded and in particular, the theory of statistical learning is discussed.
Content# Boosting: A state-of-the-art classification approach that is sometimes used as an alternative to SVMs in non-linear classification.
# Theory of estimators: How can we measure the quality of a statistical estimator? We already discussed bias and variance of estimators very briefly, but the interesting part is yet to come.
# Statistical learning theory: How can we measure the quality of a classifier? Can we give any guarantees for the prediction error?
# Variational methods and optimization: We consider optimization approaches for problems where the optimizer is a probability distribution. Concepts we will discuss in this context include:

* Maximum Entropy
* Information Bottleneck
* Deterministic Annealing

# Clustering: The problem of sorting data into groups without using training samples. This requires a definition of ``similarity'' between data points and adequate optimization procedures.
# Model selection: We have already discussed how to fit a model to a data set in ML I, which usually involved adjusting model parameters for a given type of model. Model selection refers to the question of how complex the chosen model should be. As we already know, simple and complex models both have advantages and drawbacks alike.
# Reinforcement learning: The problem of learning through interaction with an environment which changes. To achieve optimal behavior, we have to base decisions not only on the current state of the environment, but also on how we expect it to develop in the future.

AbstractThe course focuses on formal methods for the modelling and analysis of security and privacy concerns in critical systems, ranging from access control policies to cryptographic protocols.
ObjectiveThe students will learn the key ideas and theoretical foundations of formal modelling and analysis of security protocols and policies. The students will complement their theoretical knowledge by solving practical exercises and using various related tools.
ContentThe lecture treats formal methods for the modelling and analysis of security-critical systems.

The first part of the lecture focuses on access control policies in centralized and distributed settings. Access control policies are an integral part of modern Internet services; examples include single sign-on endpoints, distributed trust management in social Websites, and peer-to-peer networks. The lectures cover the formal foundations of authorization systems, and their applications to the synthesis and analysis of access control policies. We will also study a few notable existing models, such as XACML, DKAL and PBel.

The second part of the lecture concentrates on cryptographic protocols. Cryptographic protocols (such as SSL/TLS, SSH, Kerberos, SAML single-sign on, and IPSec) form the basis for secure communication and business processes. Numerous attacks on published protocols show that the design of cryptographic protocols is extremely error-prone. A rigorous analysis of these protocols is therefore indispensable. The lecture covers the theoretical basis for the formal modeling and analysis of such protocols. Specifically, we discuss their operational semantics, the formalization of security properties, and techniques and algorithms for their verification. In addition to the classical security properties for confidentiality and authentication, we will study privacy properties and the fairness property in contract signing. The accompanying tutorials provide an opportunity to apply the theory and tools to concrete protocols.

AbstractThe course teaches students about the basic principles of web engineering by examining the various technologies used in modern web sites in detail together with the step-by-step processes used to develop state-of-the art web sites.
ObjectiveThe goals of the course are that students should be able to:
- systematically develop state-of-the-art web sites using a range of technologies, platforms and frameworks in common use
- understand the role of different technologies and how they are combined in practice
- analyse requirements and select appropriate technologies, platforms and frameworks
ContentThe first half of the course will introduce the various technologies used in state-of-the-art web sites together with the step-by-step development process. From the beginning, we will cater for access from multiple devices such as mobile phones and tablets as well as desktop browsers and show how technologies such as HTML5, CSS3 and JavaScript can be used to support rich forms of interaction.

In the second half of the course, we will look at how various platforms and frameworks are used to support web site development. We will start by examining the model behind modern content management platforms such as WordPress and showing how web sites with dynamic content can be systematically developed using these platforms. This will be followed by looking at the more traditional programming approaches by first introducing the Java web technology stack and then a modern web application framework. Finally, we will present model-driven approaches to web engineering.

The material covered in lectures will be supported by a series of practical exercises that will take the students through the development processes.

AbstractThe course examines the principles and techniques of providing data management in object-oriented programming environments. After introducing the basics of object storage and management, we will cover semantic object models and their implementation. Finally, we discuss advanced data management services such as version models for temporal and engineering databases and for software configuration.
ObjectiveThe goal of this course is to extend the student's knowledge of database technologies towards object-oriented solutions. Starting with basic principles, students also learn about commercial products and research projects in the domain of object-oriented data management. Apart from getting to know the characteristics of these approaches and the differences between them, the course also discusses what application requirements justify the use of object-oriented databases. Therefore, it educates students to make informed decisions on when to use what database technology.
ContentThe course examines the principles and techniques of providing data management in object-oriented programming environments. It is divided into three parts that cover the road from simple object persistence, to object-oriented database management systems and to advanced data management services. In the first part, object serialisation and object-relational mapping frameworks will be introduced. Using the example of the open-source project db4o, the utilisation, architecture and functionality of a simple object-oriented database is discussed. The second part of the course is dedicated to advanced topics such as industry standards and solutions for object data management as well as storage and index technologies. Additionally, advanced data management services such as version models for temporal and engineering databases as well as for software configuration are discussed. In the third and last part of the course, an object-oriented data model that features a clear separation of typing and classification is presented. Together with the model, its implementation in terms of an object-oriented database management system is discussed also. Finally, an extension of this data model is presented that allows context-aware data to be managed.

AbstractComputer-Supported Cooperative Work (CSCW) is the study of how people work together using computer technology. It is a multi-disciplinary research field dealing with the social, theoretical, practical and technical aspects of collaboration and how the use of technology can affect groups, organisations and communities. The diversity of the CSCW field is reflected in the range of topics covered.
ObjectiveComputer-Supported Cooperative Work (CSCW) is the study of how people work together using computer technology. It is a multi-disciplinary research field dealing with the social, theoretical, practical and technical aspects of collaboration and how the use of technology can affect groups, organisations, communities and societies. The CSCW community is interested in how people use everyday tools such as email, the web and chat systems as well as specialist groupware applications that support groups of people engaged in shared tasks such as software development or product design. A better understanding of how people communicate and work together can in turn lead to a better understanding of the problems of current technologies and systems and influence the design of new technologies and tools.

263-2300-00LHow To Write Fast Numerical Code Information
Prerequisite: Master student, solid C programming skills.
W6 credits3V + 2UM. Püschel
AbstractThis course introduces the student to the foundations and state-of-the-art techniques in developing high performance software for numerical functionality such as linear algebra and others. The focus is on optimizing for the memory hierarchy and for special instruction sets. Finally, the course will introduce the recent field of automatic performance tuning.
ObjectiveSoftware performance (i.e., runtime) arises through the interaction of algorithm, its implementation, and the microarchitecture the program is run on. The first goal of the course is to provide the student with an understanding of this interaction, and hence software performance, focusing on numerical or mathematical functionality. The second goal is to teach a general systematic strategy how to use this knowledge to write fast software for numerical problems. This strategy will be trained in a few homeworks and semester-long group projects.
ContentThe fast evolution and increasing complexity of computing platforms pose a major challenge for developers of high performance software for engineering, science, and consumer applications: it becomes increasingly harder to harness the available computing power. Straightforward implementations may lose as much as one or two orders of magnitude in performance. On the other hand, creating optimal implementations requires the developer to have an understanding of algorithms, capabilities and limitations of compilers, and the target platform's architecture and microarchitecture.

This interdisciplinary course introduces the student to the foundations and state-of-the-art techniques in high performance software development using important functionality such as linear algebra functionality, transforms, filters, and others as examples. The course will explain how to optimize for the memory hierarchy, take advantage of special instruction sets, and, if time permits, how to write multithreaded code for multicore platforms. Much of the material is based on state-of-the-art research.

Further, a general strategy for performance analysis and optimization is introduced that the students will apply in group projects that accompany the course. Finally, the course will introduce the students to the recent field of automatic performance tuning.
263-2810-00LAdvanced Compiler Design Information W7 credits3V + 2U + 1AT. Gross
AbstractThis course covers advanced topics in compiler design: SSA intermediate representation and its use in optimization, just-in-time compilation, profile-based compilation, exception handling in modern programming languages.
ObjectiveUnderstand translation of object-oriented programs, opportunities and difficulties in optimizing programs using state-of-the-art techniques (profile-based compilation, just-in-time compilation, runtime system interaction)
ContentThis course builds conceptually on Compiler Design (a basic class for advanced undergraduates), but this class is not a prerequisite. Students should however have a solid understanding of basic compiler technology.

The focus is on handling the key features of modern object-oriented programs. We review implementations of single and multiple inheritance (incl. object layout, method dispatch) and optimization opportunities.

Specific topics: intermediate representations (IR) for optimizing compilers, static single assignment (SSA) representation, constant folding, partial redundancy optimizations, profiling, profile-guided code generation. Special topics as time permits: debugging optimized code, multi-threading, data races, object races, memory consistency models, programming language design. Review of single inheritance, multiple inheritance, object layout, method dispatch, type analysis, type propagation and related topics.

This course provides another opportunity to explore software design in a medium-scale software project.

Prerequisites / NoticeA basic course on compiler design is helpful but not mandatory. Student should have programming skills/experience to implement an optimizer (or significant parts of an optimizer) for a simple object-oriented language. The programming project is implemented using Java.
263-2910-00LProgram Analysis Information W4 credits2V + 1UM. Vechev
AbstractModern program analysis techniques are the predominant approach for automatically reasoning about real world programs -- its techniques have been applied in a vast range of application domains.

The course provides an introduction to the fundamental principles, applications, and research trends of modern program analysis.
ObjectiveThe course has 4 main objectives:

* Understand the foundational principles behind program analysis techniques.

* Understand how to apply these principles to build practical, working analyzers for real world problems.

* Understand how to combine these techniques with other approaches (e.g. machine learning techniques) to build powerful end-to-end reasoning systems, not possible otherwise.

* Gain familiarity with the state-of-the-art in the area and the future research trends in the next 5-10 years.
ContentThe last decade has seen an explosion in modern program analysis techniques. These techniques are increasingly being used to reason about a vast range of computational paradigms including:

* finding security violations in web and mobile applications such as JavaScript and Android
* practical type checking and inference (e.g. Facebook's recently released Flow analyzer).
* combinations with machine learning techniques for learning from massive programming data guiding prediction of program properties and prediction of new code.
* establishing properties of biological systems (e.g. DNA computation)
* finding serious errors in systems software (e.g. Linux kernel, device drivers, file systems)
* automatic discovery of new algorithms (e.g. concurrent data structures, distributed algorithms) and end-user programming.
* compilers for domain specific languages
* architecture-driven reasoning of concurrent software (e.g. Intel's x86, ARM, IBM's Power).

This course will provide a comprehensive introduction to modern, state-of-the-art program analysis concepts, principles and research trends, including:

* Static & Dynamic Analysis:
- concepts: memory safety, type checking and inference, typestate, concurrency analysis, abstract interpretation (domains, soundness, precision, fixed points)
- frameworks: Valgrind, FastTrack, EventRacer, Apron, PPL, Facebook's Flow analyzer.

* Statistical program reasoning:
- concepts: combining analysis with statistical models (e.g. Language models, Bayesian networks, Neural networks, etc)
- frameworks: Slang, JSNice (http://jsnice.org)

* Predicate abstraction:
- concepts: Graf-Saidi, Boolean programs, lazy abstraction
- frameworks: Microsoft's SLAM for C programs, Fender

* Symbolic execution:
- concepts: SMT, concolic execution
- frameworks: S2E, KLEE, Sage

* Security Analysis:
- concepts: static + dynamic combination
- example: malware detection

* Pointer analysis:
- concepts: Andersen's, Steensgaard's analysis
- frameworks: Soot, LLVM, WALA

* Program synthesis:
- concepts: L*, version spaces, PBE, CEGIS
- frameworks: Sketch, AGS, SmartEdit, ReSynth

* Applications of Analysis & Synthesis:
- GPU programs, security errors, device drivers, concurrent algorithms, end-user programming.

To gain a deeper understanding of how to apply these techniques in practice, the course will involve a small hands-on programming project where based on the principles introduced in class, the students will build a program reasoning engine (e.g. analysis, predictions) for a modern programming language.

252-0491-00LSatisfiability of Boolean Formulas - Combinatorics and Algorithms Information W7 credits3V + 2U + 1AE. Welzl
AbstractBasics (CNF, resolution), extremal properties (probabilistic method, derandomization, Local Lemma, partial satisfaction), 2-SAT algorithms (random walk, implication graph), NP-completeness (Cook-Levin), cube (facial structure, Kraft inequality, Hamming balls, covering codes), SAT algorithms (satisfiability coding lemma, Paturi-Pudlák-Zane, Hamming ball search, Schöning), constraint satisfaction.
ObjectiveStudying of advanced methods in algorithms design and analysis, and in discrete mathematics along a classical problem in theoretical computer science.
ContentSatisfiability (SAT) is the problem of deciding whether a boolean formula in propositional logic has an assignment that evaluates to true. SAT occurs as a problem and is a tool in applications (e.g. Artificial Intelligence and circuit design) and it is considered a fundamental problem in theory, since many problems can be naturally reduced to it and it is the 'mother' of NP-complete problems. Therefore, it is widely investigated and has brought forward a rich body of methods and tools, both in theory and practice (including software packages tackling the problem).
This course concentrates on the theoretical aspects of the problem. We will treat basic combinatorial properties (employing the probabilistic method including a variant of the Lovasz Local Lemma), recall a proof of the Cook-Levin Theorem of the NP-completeness of SAT, discuss and analyze several deterministic and randomized algorithms and treat the threshold behavior of random formulas.
In order to set the methods encountered into a broader context, we will deviate to the more general set-up of constraint satisfaction and to the problem of proper k-coloring of graphs.

Content# Boosting: A state-of-the-art classification approach that is sometimes used as an alternative to SVMs in non-linear classification.
# Theory of estimators: How can we measure the quality of a statistical estimator? We already discussed bias and variance of estimators very briefly, but the interesting part is yet to come.
# Statistical learning theory: How can we measure the quality of a classifier? Can we give any guarantees for the prediction error?
# Variational methods and optimization: We consider optimization approaches for problems where the optimizer is a probability distribution. Concepts we will discuss in this context include:

* Maximum Entropy
* Information Bottleneck
* Deterministic Annealing

# Clustering: The problem of sorting data into groups without using training samples. This requires a definition of ``similarity'' between data points and adequate optimization procedures.
# Model selection: We have already discussed how to fit a model to a data set in ML I, which usually involved adjusting model parameters for a given type of model. Model selection refers to the question of how complex the chosen model should be. As we already know, simple and complex models both have advantages and drawbacks alike.
# Reinforcement learning: The problem of learning through interaction with an environment which changes. To achieve optimal behavior, we have to base decisions not only on the current state of the environment, but also on how we expect it to develop in the future.

AbstractThe goal of this course is the in-depth understanding of the technology and programming underlying computer games. Students gradually design and develop a computer game in small groups and get acquainted with the art of game programming.
ObjectiveThe goal of this new course is to acquaint students with the
technology and art of programming modern three-dimensional computer
games.
ContentThis is a new course that addresses modern three-dimensional computer
game technology. During the course, small groups of students will
design and develop a computer game. Focus will be put on technical
aspects of game development, such as rendering, cinematography,
interaction, physics, animation, and AI. In addition, we will
cultivate creative thinking for advanced gameplay and visual effects.

The "laboratory" format involves a practical, hands-on approach with
neither traditional lectures nor exercises. Instead, we will meet
once a week to discuss technical issues and to track progress. We
plan to utilize Microsoft's XNA Game Studio Express, which is a
collection libraries and tools that facilitate game development.
While development will take place on PCs, we will ultimately deploy
our games on the XBox 360 console.

At the end of the course we will present our results to the public.

252-5705-00LImage Synthesis Information W6 credits5GW. Jarosz, W. A. Jakob
AbstractThis course covers advanced topics in rendering and image synthesis.
ObjectiveThe goal is to get a broader knowledge of rendering algorithms and an in-depth understanding of advanced topics in rendering. Students will learn about the principles of how light interacts with a scene, and how to translate the associated image formation problem into efficient rendering algorithms. Since this is an upper-level coarse, a focus is placed on state of the art techniques and recent trends in research.
ContentThis course expands upon the rendering foundation taught in the Computer Graphics course.

We assume a basic knowledge of ray tracing and shading, and expand significantly on the physics of light transport, discuss the rendering equation, and focus significant time on advanced techniques to enhance the realism and lower the computational cost of rendered images.

Starting from a review of the physics underlying a range of complex light transport effects (depth-of-field, soft shadows, global illumination, participating media, subsurface scattering), we discuss how to leverage various mathematical tools (e.g. density estimation, Monte Carlo sampling, Markov Chain Monte Carlo) to obtain a range of state-of-the-art rendering algorithms (including variants of path tracing, photon mapping, and Metropolis light transport).

The course includes a rendering competition where students create a realistic image of their choosing using the rendering software they develop in the course.

AbstractThis course focuses on neural computations that underlie visual perception. We study how visual signals are processed in the retina, LGN and visual cortex. We study the morpholgy and functional architecture of cortical circuits responsible for pattern, motion, color, and three-dimensional vision.
ObjectiveThis course considers the operation of circuits in the process of neural computations. The evolution of neural systems will be considered to demonstrate how neural structures and mechanisms are optimised for energy capture, transduction, transmission and representation of information. Canonical brain circuits will be described as models for the analysis of sensory information. The concept of receptive fields will be introduced and their role in coding spatial and temporal information will be considered. The constraints of the bandwidth of neural channels and the mechanisms of normalization by neural circuits will be discussed.
The visual system will form the basis of case studies in the computation of form, depth, and motion. The role of multiple channels and collective computations for object recognition will
be considered. Coordinate transformations of space and time by cortical and subcortical mechanisms will be analysed. The means by which sensory and motor systems are integrated to allow for adaptive behaviour will be considered.

AbstractThis course unit looks into algorithmic approaches to the solving of hard problems. The seminar is accompanied by a comprehensive reflection upon the significance of the approaches presented for computer science tuition at high schools.
ObjectiveTo systematically acquire an overview of the methods for solving hard problems.
ContentFirst, the concept of hardness of computation is introduced (repeated for the computer science students). Then some methods for solving hard problems are treated in a systematic way. For each algorithm design method, it is discussed what guarantees it can give and how we pay for the improved efficiency.

272-0302-00LApproximation and Online Algorithms Information W4 credits2V + 1UH.‑J. Böckenhauer, D. Komm
AbstractThis lecture deals with approximative algorithms for hard optimization problems and algorithmic approaches for solving online problems as well as the limits of these approaches.
ObjectiveGet a systematic overview of different methods for designing approximative algorithms for hard optimization problems and online problems. Get to know methods for showing the limitations of these approaches.
ContentApproximation algorithms are one of the most succesful techniques to attack hard optimization problems. Here, we study the so-called approximation ratio, i.e., the ratio of the cost of the computed approximating solution and an optimal one (which is not computable efficiently).
For an online problem, the whole instance is not known in advance, but it arrives pieceweise and for every such piece a corresponding part of the definite output must be given. The quality of an algorithm for such an online problem is measured by the competitive ratio, i.e., the ratio of the cost of the computed solution and the cost of an optimal solution that could be given if the whole input was known in advance.

The contents of this lecture are
- the classification of optimization problems by the reachable approximation ratio,
- systematic methods to design approximation algorithms (e.g., greedy strategies, dynamic programming, linear programming relaxation),
- methods to show non-approximability,
- classic online problem like paging or scheduling problems and corresponding algorithms,
- randomized online algorithms,
- the design and analysis principles for online algorithms, and
- limits of the competitive ratio and the advice complexity as a way to do a deeper analysis of the complexity of online problems.
