Neural Networks and Deep Learning

PhD Course, 3 + 3 credits, Autumn 2019.
Instructors: Michael Felsberg (ISY), Marco Kuhlmann (IDA)

Over the past few years, neural networks have enjoyed a major resurgence in machine learning, and today yield state-of-the-art results in various fields. This course provides an introduction to deep neural network models, and surveys some the applications of these models in areas where they have been particularly successful. The course covers feedforward networks, convolutional networks, recurrent and recursive networks, as well general topics such as input encoding and training techniques. The course also provides acquaintance with some of the software libraries available for building and training deep neural networks.

Syllabus

Prerequisites

Gaps in these prerequisites may be filled by teacher-assisted self-study before the start of the course; contact the instructors for details.

Intended learning outcomes

On successful completion of the course you should be able to:

Contents

Basics of machine learning (regression, classification, numerical optimisation). Feedforward networks. Loss functions. Back-propagation training. Regularisation. Convolutional networks. Recurrent and recursive networks. Processing sequences, images, and hierarchical structures. Applications of neural networks. Current areas of research.

Course literature

The main book for the course is:

Ian Goodfellow, Yoshua Bengio, and Aaron Courville. Deep Learning. MIT Press, 2016.

Additional reading consists of excerpts from the following books:

Organisation

Lectures

The lectures present basic concepts and methods in neural networks and survey applications. Each lecture connects to one or several chapters in the book by Goodfellow, Bengio, and Courville (GBC). The course schedule indicates which chapters you should have read before each lecture.

Labs

The labs give you practical experience in implementing, training, and evaluating neural networks using existing software libraries. There are a total of four labs:

Lab 0 is a preparatory lab that you do on-site. For each of the remaining labs there is an on-site introduction by an instructor, but most of the actual work is self-scheduled.

In order to do labs 0–2, you will need to bring your own computer and install the following software: Python 3, Jupyter Notebook, NumPy, TensorFlow, Keras. We recommend installing this software using Virtualenv or Anaconda. It is a good idea to install this software before the start of the course, but you can also get help with the installation during lab 0.

Individual project

The second (optional) part of the course is an individual project that you formulate together with your PhD supervisor. We anticipate the typical project to be one where you apply neural networks to a concrete problem related to your thesis work. To be acceptable for the course, the project must contain a substantial amount of machine learning; in case of doubt about this, your supervisor is welcome to consult with us (the instructors).

Here is the process for the individual project:

Examination

The examination for the course consists of two parts:

Based on whether or not you choose to do the project, you will get either 6 credits or 3 credits for this course.

Dates relevant to the examination:

Lab assignments submitted after the first due date will be graded after the deadline for late submissions in January.

To meet a due date or deadline, it suffices to submit the assignment before 08:00 the first working day after that date.

Schedule

The lectures, lab sessions, and seminars take place in the B-building and the E-building at Campus Valla.
