WebNov 11, 2024 · Implementing the gradient descent In this session, we shall assume we are given a cost function of the form: J(θ) = (θ − 5) 2 and θ takes values in the range 10. Let us start by importing libraries we will be working with: import numpy as np import matplotlib.pyplot as plt Generate some random data points WebMar 13, 2024 · In this article, we have discussed the gradient descent and stochastic gradient descent that is used for optimising the parameters of any function. Along with the discussion we have also gone through an idea that can help us in implementing stochastic gradient descent using python. References. Link for the codes
Gradient Descent For Machine Learning
WebJun 6, 2024 · 2 Answers. The problem with the contour graph is that the scales of theta0 and theta1 are different. Just add "plt.axis ('equal')" to the contour plot instructions and you will see that the gradient descent is in fact perpendicular to the contour lines. In general, Gradient Descent do not follow contour lines.
