Summary
Statistical machine learning is a growing discipline at the intersection
of computer science and applied mathematics (probability / statistics,
optimization, etc.) and which increasingly plays an important role in technological
innovation.
Unlike a course on traditional statistics, statistical machine learning
is particularly focused on the analysis of data in high dimension, as well
as the efficiency of algorithms to process the large amount of data encountered
in multiple application areas such as image or sound analysis, natural
language processing, bioinformatics or finance.
The objective of this class is to present the main theories and algorithms
in statistical machine learning. The methods covered will rely amongst
others on convex analysis arguments. The practical sessions (more than
half of which will be realized with computers) will lead to simple implementations
of the algorithms seen in class and with applications to various domains
such as computer vision or natural language processing.
Prerequisite: probability theory (notion of random variables, convergence
of random variables, conditional expectation), coding skills in python.
General information
This class is part of the Computer science courses taught at ENS in L3
in Spring 20192020.
