An introduction to recurrent neural networks

Alessio Micheli
Dipartimento di Informatica, Università degli Pisa

The aim of the course is to introduce the student to the architectures and learning methods for dynamical/recurrent neural networks for temporal data and the analysis of their properties.
The students will learn the differences and the advantages of the different approaches to learn sequential data by neural networks. Basic models, which allow representing time in a neural networks, will be detailed along with their learning algorithms. Advanced models, which are playing a key role in the current Artificial intelligence “revolution”, will be also introduced with an emphasis on simple and efficient approaches. Examples of applications in various fields including signal processing, human language processing and  human activity recognition will accompany the model presentation.

- Introduction to the problem and methodology: Time representation in neural networks: explicit and implicit forms.
- Recurrent Neural Networks: Models and architectures; Properties (stationarity, causality, unfolding)
- Learning algorithms: BPTT, RTRL.
- Analysis: architectural bias. Reservoir Computing.
- Advanced RNN models. Related approaches and extensions.
- Applications: Case studies.
