Course Aim & Organization

Neural networks are mature, flexible, and powerful non-linear data-driven models that have successfully been applied to solve complex tasks in science and engineering. The advent of the deep learning paradigm, i.e., the use of (neural) network to simultaneously learn an optimal data representation and the corresponding model, has further boosted neural networks and the data-driven paradigm.

Nowadays, deep neural network can outperform traditional hand-crafted algorithms, achieving human performance in solving many complex tasks, such as natural language processing, text modeling, gene expression modeling, and image recognition. The course provides a broad introduction to neural networks (NN), starting from the traditional feedforward (FFNN) and recurrent (RNN) neural networks, till the most successful deep-learning models such as convolutional neural networks (CNN) and long short-term memories (LSTM).

The course major goal is to provide students with the theoretical background and the practical skills to understand and use NN, and at the same time become familiar and with Deep Learning for solving complex engineering problems.

Teachers

The course is composed of a blending of lectures and exercises by the course teachers and a teaching assistant.

Course Program and Syllabus

This goal is pursued in the course by:

  • Presenting major theoretical results underpinning NN (e.g., universal approx, vanishing/exploding gradient, etc.)
  • Describing the most important algorithms for NN training (e.g., backpropagation, adaptive gradient algorithms, etc.)
  • Illustrating the best practices on how to successfully train and use these models (e.g., dropout, data augmentation, etc.)
  • Providing an overview of the most successful Deep Learning architectures (e.g., CNNs, sparse and dense autoencoder, LSTMs for sequence to sequence learning, etc.)
  • Providing an overview of the most successful applications with particular emphasis on models for solving visual recognition tasks.

We have compiled a detailed syllabus of the course student can use to doublecheck their preparation against before the exam.

  • Course Syllabus: a detailed list of topics covered by the course and which students are expected to know when approaching the exam

Course Evaluation

Course evaluation is composed of two parts:

  • A written examination covering the whole program graded up to 27/32
  • A home project in the form of a Kaggle style competition practicing the topics of the course graded up to 5/32

The final score will sum the grade of the written exam and the grade of the home project.

You can find here one example of the exam text to get a flavor of what to expect in the written examination.

Teaching Material (the textbook)

Lectures will be based on material from different sources, teachers will provide their slides to students as soon they are available. As a general reference you can check the following text, but keep in mind that teachers will not follow it strictly

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

Course Slides

Slides from the lectures by Matteo Matteucci

Slides from the lectures by Giacomo Boracchi are available in his webpage, for you

  • Image Classification: Image classification and related issues, template matching, image classification via nearest neighbors methods, image classification via linear classifiers, image classification via hand-crafted features.

Kaggle Homeworks

As part of the evaluation (up to 5 marks in the final grade) we are issuing 3 homeworks in the form of Kaggle competitions. They are meant to practice the course topics on simple image recognition tasks.

  • Image Classification Homework: the first homework is about image classification with convolutional neural networks. The deadline to submit the results is November the 30th.
  • Image Segmentation Homework: the second homework is about image segmentation with convolutional neural networks and the like. The deadline to submit the results is December the 17th.
  • Visual Question Answering Homework: the third homework is about visual question answering with convolutional and recurrent neural networks ... plus word2vec. The deadline to submit the results is January the 15th.
