We will go through some of the topics in machine learning covering (1) supervied learning: ensemble-based discriminative learning (bagging, boosting, and random forest), (2) support vector machine (SVM) families (svm, structural svm, latent svm), (3) semi-supervised learning (transductive learning, graph Laplacian), (4) unsupervised manifold/metric learning, (5) sparsity and low-rank, (6) hierarchical models (deep learning, active basis, and biology driven models).

Grading policy: Two small projects with a medium-size project.
