Loss Function

Loss function, in essence is to measure how badly the machine learning algorithm screwed up the prediction quantitatively. Definition from Stanford open course is To have a concrete feeling, the below example from this blog post is more straightforward. There are multiple ways to measure the loss, mean squared error (MSE), likelihood loss, log loss(cross … Continue reading Loss Function
