Witryna14 paź 2024 · Hypothesis Implementation: For Loop. In order to achieve the hypothesis function of linear regression, if we use for loop, it can be achieved using the following code: # hypothesis for the first sample hypo = 0 for j in range(n): hypo += theta[j]*X[0,j] Witryna8 maj 2024 · NOTE: Here our target is to find the optimum value for the parameters θ. To find the optimum value for θ we can use the normal equation. So after finding the values for θ, our linear hypothesis or linear model will be ready to predict the price for new features or inputs.
