Project 1 - Predicting Boston Housing Prices

Model Evaluation and Validation

• Built a model to predict the value of a given house in the Boston real estate market (standard dataset) using various statistical analysis tools.

• Identified the best price that a client can sell their house using machine learning techniques.

Project 2 - Building a Student Intervention System

Supervised Learning

• Trained and tested several supervised machine learning models on a given dataset to predict how likely a high school student is to pass.

• Selected the best model based on relative accuracy and efficiency.

• Classifiers trained and tested include Decision Trees, Support Vector Machines (SVMs) and K-Nearest Neighbors (k-NN).

Project 3 - Explore the Clusters in a Dataset

Unsupervised Learning

• Reviewed unstructured data to understand the patterns and natural categories that the data fits into.

• Used multiple algorithms (PCA, ICA and clustering) and compared and contrasted their results both empirically and theoretically.

• Made predictions about the natural categories of multiple types in a dataset, then checked these predictions against the result of unsupervised analysis.

Project 4 - Train a Smartcab How to Drive

Reinforcement Learning

• Applied reinforcement learning to build a simulated vehicle navigation agent. This project involved modeling a complex control problem in terms of limited available inputs, and designing a scheme to automatically learn an optimal driving strategy based on rewards and penalties.
