# Experiment 2: Logistic Regression and Newton's Method August 29, 2018 ## 1 Description In this exercise, you will use Newton’s Method to implement logistic regression on a classification problem your program and add the $ x_{0}=1 $ intercept term into your x matrix. Before beginning Newton’s Method, we will first plot the data using different symbols to represent the two classes. In Matlab/Octave |L^{+}(\theta)-L(\theta)|\leq\epsilon $$ Try to resolve the logistic regression problem using gradient descent method with the initialization $ \theta = 0 $ , and answer the following questions: 1. Assume $ \epsilon
