Summary

A course on statistical methods for supervised and unsupervised learning.

Content

• Introduction: supervised and unsupervised learning, loss functions, train and test errors, bias-variance tradeoff, model complexity and overfitting, linear regression, k-nearest neighbors.
• Regression: linear regression, model selection, ridge and Lasso.
• Classification: linear discriminant analysis, logistic regression.
• Resampling methods: cross-validation, bootstrap.
• Nonparametric regression: smoothing splines, reproducing kernel Hilbert spaces.
• Support vector machines and kernel logistic regression.
• Tree-based methods: classification and regression trees, bagging, random forests.
• Boosting: AdaBoost, gradient boosting machines.
• Deep learning: introduction to convolutional neural networks.
• Unsupervised learning: principal component analysis, k-means, Gaussian mixtures and the EM algorithm.

Learning Prerequisites

Required courses

Analysis, Linear Algebra, Probability and Statistics, Linear Models

Important concepts to start the course

This is a statistics/mathematics course. Prior to following this course, the student must have very good knowledge of basic probabilty and statistics (statistical modeling and inference, linear regression).

Learning Outcomes

By the end of the course, the student must be able to:

• Formulate appropriate models for empirical data
• Estimate the parameters of a statistical model
• Interpret the fit of a model to data
• Justify the choice of a model/technique to analyze empirical data
• Implement statistical learning algorithms
• Explain the mathematical/statistical mechanisms of most common machine learning algorithms

Teaching methods

Ex cathedra lectures, exercises and computer practicals in the classroom and at home.

Assessment methods
