What is Cost Function in Machine Learning
Ans: The cost function is the technique of evaluating “the performance of our algorithm/model”. It takes both predicted outputs by the model and actual outputs and calculates how much wrong the model was in its prediction. It outputs a higher number if our predictions differ a lot from the actual values.
