Logistic regression with pytorch
Witryna24 cze 2024 · I’m solving it by relaxing the problem by approximating the indicator loss with logistic loss as in a logistic regression. Note that the generate_data (n, d) function just generates a random data frame of size n x d. However, when I run the below routine, it does not decrease the objective; if anything it increases it. http://whatastarrynight.com/machine%20learning/operation%20research/python/Constructing-A-Simple-Logistic-Regression-Model-for-Binary-Classification-Problem-with-PyTorch/
