Course Information
The class focuses on fundamental mathematical aspects of neural networks with an emphasis on deep networks.
- Universal approximation with single- and multi-layer networks
- Introduction to approximation theory: Fundamental limits on compressibility of signal classes, Kolmogorov epsilon-entropy of signal classes, non-linear approximation theory
- Fundamental limits of deep neural network learning
- Geometry of decision surfaces
- Separating capacity of nonlinear decision surfaces
- Vapnik-Chervonenkis (VC) dimension
- VC dimension of neural networks
- Generalization error in neural network learning
Prerequisites
The course is aimed at students with a strong mathematical background in general, and in linear algebra, analysis, and probability theory in particular.

Handwritten notes
Here we will post notes written on the iPad during the lectures.Problem sets and solutions
There will be several problem sets for this course, which will help you better understand the lectures and prepare you for the exam. All the problem sets will be discussed in the exercise session, and the solutions will be uploaded afterwards.
Parts of the notes relevant for the exam:
- Sections 2.2, 2.3, 2.4, 2.5, 2.6, 2.7.
- All of the handwritten notes on second part of class.
- All problem sets.
