The course introduces the fundamental aspects of AI ethics by providing a holistic multidisciplinary view of the discipline. The course structure is such as to introduce students to the impact AI systems have on societies and individuals and ongoing state-of-the-art discussions related to Ethical, Legal and Societal aspects of AI. This course aims to foster critical discussion of where accountability and responsibility lie for ethical, legal, and social impacts of AI systems, considering decision points throughout the development and deployment pipeline. Students will be introduced to socio-technical approaches for the governance, monitoring and control of intelligent systems as well as tools for incorporating constraints into intelligent system design and will apply these skills on a simulated responsible AI design problem.

Autonomous systems are systems that are designed to work without, or with limited, human intervention. The objective of this course is to give a broad understanding of the wide area of autonomous systems and the foundational knowledge in some topic areas required to understand and develop autonomous systems. The course covers topics from sensing and perception to control and decision making. Learning outcomes include the notion of autonomy and understanding the different components that typically are found in these systems. Other learning outcomes are fundamental techniques for autonomous systems from the areas of automatic control, sensor fusion, learning, and software. The examination consists of assignments done individually and in groups.

Artificial Intelligence is a broad topic and has emerged as an increasingly powerful subject within the field of computer science. Today, AI applications are embedded in many products and solutions in a plethora of applications ranging from traditional industry, medical diagnosis, speech recognition, robotics, web search and so much more.

This course is designed as the first graduate course and it introduces the basic concepts by focusing on an intuitive understanding, an algorithmic and mathematical perspective. The course starts by providing an overview of what the latest generation of Artificial Intelligence techniques can achieve. Then it covers the most important concepts and techniques. For each of these techniques, the course will illustrate both the potential and current limitations. We also spend some time on machine learning methods. For all these techniques we provide an introspection into the mathematical foundations and concepts behind them. Through the use of exercises, and a programming project, students get the opportunity to further apply in their knowledge in a practical moments.

Software engineering is a broad set of techniques that aim to analyze user requirements, and then facilitate the design, building, and testing of software applications.

Natural Language Processing (NLP) develops methods for making human language accessible to computers. The goal of this course is to provide students with a theoretical understanding of and practical experience with the advanced algorithms that power modern NLP. The course focuses on methods based on deep neural networks.

The course covers state-of-the-art deep learning architectures for three types of NLP applications: categorization, structured prediction, and text generation. Each module consists of video lectures, interactive sessions, and programming assignments. The final part of the course is a project where students apply their learning to their own field of research.

The purpose of this course is to give a thorough introduction to deep machine learning, also known as deep learning or deep neural networks. Over the last few years, deep machine learning has dramatically changed the state-of-the-art performance in various fields including speech-recognition, computer vision and reinforcement learning (used, e.g., to learn how to play Go).

The first module starts with the fundamental concepts of supervised machine learning, deep learning and convolutional neural networks (CNNs). This includes the main components in feed-forward and CNNs, commonly used loss functions, training paradigms, architectures and strategies to help the network generalize well to unseen data.

The second module covers algorithms used for training of neural networks such as stochastic gradient descent and Adam. We will introduce the methods and discuss their implicit regularizing properties in connection to generalization of neural networks in the overparameterized setting.

The last module of the course presents the theory behind some advanced topics of deep learning research, namely recently developed methods for 1) equipping discriminative deep networks with estimates of their uncertainty and 2) different types of deep generative models. The students’ knowledge will be examined with corresponding hand-in assignments.

Probabilistic graphical models play a central role in modern statistics, machine learning, and artificial intelligence. Within these contexts, researchers and practitioners alike are often interested in modeling the (conditional) independencies among variables within some complex system. Graphical models address this problem combinatorically: A probabilistic graphical model associates jointly distributed random variables in the system with the nodes of a graph and then encodes conditional independence relations entailed by the joint distribution in the edge structure of the graph. Consequently, the combinatorial properties of the graph play a role in our understanding of the model and the associated inference problems. We will see in this course how the graph structure provides the scientist with (1) a transparent and tractable representation of relational information encoded by the model, (2) effective approaches to exact and approximate probabilistic inference, and (3) data-driven techniques for learning graphical representatives of relational information, such as conditional independence structure or cause-effect relationships.

This course aims to introduce various aspects of interaction and collaboration with and between autonomous or robotic systems, including also visualization techniques and tangible interfaces as central topics. It will be given in a combination of theoretical lecture session meetings and project work, where a project topic close to the own research area can be chosen. The theoretical lecture sessions will provide a general introduction to Human Robot Interaction (where Robot can mean any kind of agent or system connected to the WASP areas) and collaboration, as well as deeper insights into dialogue systems, tangible interfaces, and visualization techniques.  While referred to as “theoretical”, also in these sessions hands-on exercises are planned. The course is suggested as suitable across all WASP areas, as it is assumed that most of the outcomes of the work done in WASP would not make sense in a vacuum, i.e. without considering their use and users.

Human perception relies to a large extent on vision, and we experience our vision-based understanding of the world as something intuitive, natural, and simple. The key to our visual perception is a feature abstraction pipeline that starts already in the retina. Thanks to this learned feature representation we are able to recognize of objects and scenes from just a few examples, do visual 3D navigation and manipulation, and understand poses and gestures in real-time. Modern machine learning has brought similar capabilities to computer vision and the key to this progress are the internal feature representations that are learned from generic or problem specific datasets to solve a wide range of classification and regression problems.

This course introduces the basic concepts and mathematical tools that constitute the foundations of the theory of machine learning. Learning theory concerns questions such as: What kinds of guarantees can we prove about practical machine learning methods, and can we design algorithms achieving desired guarantees? Is Occam’s razor a good idea and what does that even mean? What can we say about the fundamental inherent difficulty of different types of learning problems?

To answer these questions, the course discusses fundamental concepts such as probably approximately correct (PAC) learnability, empirical risk minimization and VC theory, and then covers the main ML subfields, including supervised learning (linear classification and regression, SVM, and deep learning), unsupervised learning (clustering), and reinforcement learning.

The examination consists of two homework assignments and a take-home exam.

Reinforcement Learning (RL) is one of the main branches of Machine Learning allowing a system to learn through a trial-and-error process. The emerging field of RL has led to impressive results in varied domains like strategy games, robotics, etc. This course aims to give a deep understanding of the wide area of RL, build the basic theoretical foundation, and summarize state-of-the-art RL algorithms. The course covers topics from sequential decision making, probability theory, optimization, and control theory. At the end of this course, students will be able to formalize a task as an RL problem, have practical skills to implement recent advances in RL, and are ready to contribute to this field.

Large clusters composed of a network of commodity computers with new hardware, including GPUs, TPUs, CPUs, and SSDs, are today’s workhorses for solving various problems that scale to large datasets using parallel and distributed algorithms. This course is a theoretical and practical introduction to the subject.

Topics include analysis of distributed and parallel algorithms for sorting, optimization, numerical linear algebra, machine learning, graph analysis, streaming algorithms, and other problems that are challenging to scale on a commodity cluster. The course, offered in collaboration with Stanford University, will have a theoretical focus on the mathematical analysis of algorithms, and a practical focus on implementation in a cluster with real data.

The course has three modules:

Module 1 – Introduction to data science & analysis of parallel algorithms.

Module 2 – Introduction to distributed algorithms for data science & machine learning.

Module 3 – Diving deeper

How to give a machine a sense of geometry? There are two aspects of what a sense is: a technical tool and an ability to learn to use it. This learning ability is essential. For example we are born with the technical ability to detect smells and throughout our lives we use and develop this sense, depending on needs and the environment around us. In this course the technical tool we introduce to describe geometry is based on homology. The main aim of the course is to explain how versatile this tool is and how to use this versatility to give a machine the ability to learn to sense geometry.

Technical tool. Homology, the central theme of the 20th century geometry, has been particularly useful for studying spaces with controllable cell decompositions such as Grassmann varieties. During the last decade there has been an explosion of applications ranging from neuroscience to vehicle tracking, protein structure analysis and the nano characterization of materials, testifying to the usefulness of homology to describe also spaces related to data sets. One might ask: why homology? Often due to heterogeneity or the presence of noise, it is very hard to understand our data. In these cases rather than trying to fit the data with complicated models a good strategy is to first investigate the shape properties of such data. Here homology comes into play.

Learning. We explain how to use homology to convert geometry of datasets into features suitable for statistical analysis and machine learning. It is a process that translates spacial and geometrical information into information that can be analysed through more basic operations such as counting and integration. Furthermore we provide an entire space of such translations.

The objective with this course is to develop experience from working on a practical problem
within the areas of AI, autonomous systems, and software. Important aspects are to work in
the form of a group including different competences and to collaborate with an external
partner, directly or indirectly, connected to Swedish industry. The course is performed as independent project groups with 5-7 students. The result from the technical work in these groups are presented in the form of a report and presentations.

A higher level artificial intelligence should be able to express knowledge and reason about it, e.g. draw conclusions from facts or from assumptions. This can be achieved by using some kind of  language. Formal (or symbolic) languages have been constructed partly for the sake of turning the “art of making conclusions”, and related problems, into a mathematically precise activity, and partly to facilitate the automation of reasoning. The formal languages of propositional logic and first-order logic are the cornerstones of the formal approaches to knowledge representation and deduction, and the multitude of other formal logical languages that exist are modifications or extensions of these. This course is an introduction to the key notions and results of propositional and first-order logic.

This is an introductory course targeting students with a less strong background in mathematics. The student should get the theoretical mathematical background knowledge expected for the machine learning parts of all WASP-courses
