WebAug 25, 2024 · Neural networks generally perform better when the real-valued input and output variables are to be scaled to a sensible range. For this problem, each of the input variables and the target variable have a Gaussian distribution; therefore, standardizing the data in this case is desirable. WebJul 28, 2024 · Optimization in machine learning generally follows the same format. First, define a function that represents a loss. Then, by minimizing this loss, the model is forced to produce increasingly improved performance. Loss functions are chosen for two main reasons. The first is that they represent the problem well.
