WebJun 9, 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.
