NettetGradient Descent with Linear Regression ¶. Gradient descent is a name for a generic class of computer algorithms which minimize a function. These algorithms achieve this end by starting with initial parameter values and iteratively moving towards a set of parameter values that minimize some cost function or metric—that's the descent part.
Nettet9. jun. 2024 · By simple linear equation y=mx+b we can calculate MSE as: Let’s y = actual values, yi = predicted values. Using the MSE function, we will change the values of a0 and a1 such that the MSE value settles at the minima. Model parameters xi, b (a0,a1) can be manipulated to minimize the cost function.
