Neural Networks and Deep Learning for Life Sciences and Health Applications
Description
This course offers a case-based introduction on the basis of the book
U. Michelucci, Applied Deep Learning: A Case-Based Approach to Understanding Deep Neural Networks, APRESS, ISBN: 978-1-4842-3789-2
Why offer a course on applied deep learning? After all, try a google search on the subject and you will be overwhelmed by the huge number of results. The problem is that there is no course, blog or book that teaches in a consolidated and beginner friendly way advanced subjects like regularization, advanced optimisers as Adam or RMSProp, mini-batches gradient descent, dynamical learning rate decay, dropout, hyperparameter search, bayesian optimisation, metric analysis and so on.
I found material (and typically of very bad quality) only to implement very basic models on very simple datasets. If you want to learn how to classify the MNIST (hand written digits) dataset of 10 digits you are in luck (almost everyone with a blog havs done that, mostly copying the code you find on the tensorflow website). Searching something else to learn how logistic regression works? Not so easy. How to prepare a dataset to perform an interesting binary classification? Even more difficult. The goal of this course is to let you see more advanced material with new eyes. I cover the mathematical background as much as I can because I feel it is necessary for a complete comprehension of the difficulties and reasoning behind many concepts. You cannot understand why a big learning rate will make your model (strictly speaking the cost function) diverge, if you don't know how the gradient descent algorithm works mathematically. In all real-life projects, you will not have to calculate partial derivatives or complex sums, but you need to understand them to be able to evaluate what can work and what cannot (and especially why).

Objectives and content
Target audience
This course is for people who are willing to learn what deep learning is and are not scared by a challenge. You should be someone who has some background in programming (not necessarily in Python) and some background in Mathematics. If you are a beginner is fine. We will cover the basics you need, but you may need to work a bit more on your own during the classroom lectures. I will try to help you and direct you toward the right material as much as I can. In our two introductory weeks we will also cover what we need in term of mathematics and Python. This course is for you also if you are an experienced data scientist but has not worked with neural networks before. You will be able to focus on the mode specific deep learning topics and not waste time with the basics, using the time to dig deeper in the topics explained. I am happy to help you go deeper that what we will be able to cover in the hours we have during the lectures.
