Nettet9. nov. 2024 · Not too sure what your question is. Could you clarify what are your input features and what you are trying to predict. If your output is binary, I would suggest using softmax function and your objective function for optimization should be a cross-entropy. Using a polynomial regressor is not appropriate in this case.
