Machine learning exercises done in Python

Machine Learning in Python

These are completed homework exercises from Andrew Ng's Coursera course on Machine Learning, except instead of using Matlab/Octave as required by the course, I've done the exercises in Python. If the exercise called for writing one's own routine or function in Octave, I generally tried to do the same think with pandas and numpy and then do it a third time using scikit-learn. Sometimes this meant rewriting some of the provided Octave routines.

1. Linear Regression
2. Logistic Regression
