Introduction to Machine Learning

We'll start by describing what machine learning is, and introduce a simple learning algorithm: linear regression + gradient descent. Using this algorithm, we'll introduce the core concepts in machine learning: model parameters, cost function, optimization method, and overfitting and regularization.

Supervised Learning Algorithms (Simple)

In this section, we'll see various algorithms for supervised machine learning. Different algorithms perform better for different types of data, where deciding factors would include total number of dimensions in input data, whether the data is text or numerical or a time series, whether or not the data is sparse, size of dataset, and so on. For each algorithm, we'll explain how it works and the applications for which it produces state-of-the-art results.

Supervised Learning Algorithms (Intermediate)

This section covers more algorithms for supervised machine learning. However, some of these algorithms require more mathematical maturity, such as Support Vector Machines and Hidden Markov Models.

Deep Learning

In this section, we'll learn about deep learning! We'll also compare deep learning to traditional machine learning algorithms (which we encountered in the previous section), and see how they differ.

Unsupervised Learning Algorithms

In this section, we'll cover unsupervised learning concepts such as clustering, dimensionality reduction, the curse of dimensionality, feature extraction and feature selection. We'll also learn some algorithms such as K-means clustering and Principal Component Analysis.

Note: K-nearest neighbors and matrix factorization algorithms covered in the previous sections can also be used for unsupervised learning, and in particular, for modeling similarity or relatedness between items.
