4. Supervised Learning
● Data Driven
● Key Algorithms include
– Regression
– Naive Bayes
– Support Vector Machines (SVM)
– Classification and Regression Trees
6. Unsupervised Learning
● Clustering.
– k-means.
– hierarchical clustering
● Anomaly detection.
● Approaches for learning latent variable
models such as.
– Expectation–maximization algorithm (EM)
– Method of moments.
7. K-Means Clustering
● k-means clustering aims to partition
observations into k clusters
● each observation belongs to the cluster with the
nearest mean
9. Reinforcement Learning
● An Reinforcement Learning agent learns by
receiving a reward or reinforcement from its
environment.
● No form of supervision other than its own
decision making policy.
