Plotting data, linear regression with one variable, gradient descent, and cost function implementation on housing prices data. This program uses linear regression to calculate housing prices based on training parameters given,

Machine-Learning-Linear-Regression

This program uses linear regression to calculate housing prices based on the training parameters given. Involves: plotting data, linear regression with one variable, gradient descent / cost function, feature normalization, and linear regression with multiple variables.

Some theory about the project...

Linear Regression Cost Function Forumla:

Gradient Descent (updating all theta values simultaneously):

Hypothesis Function:

Vectorized Cost Function:

Implementation based off of Standford Universities Machine Learning course/data.
