WitrynaRight now I'm training with max_iter=5000, which is very slow. To get an idea of whether this is necessary, rather than just changing max_iter ad hoc and seeing if the results are similar, I'd like to actually see how the loss evolves over each training iteration and what the model predicts during each iteration. Witryna11 sty 2024 · max_iter is the number of iterations. solver is the algorithm to use for optimization. class_weight is to troubleshoot unbalanced data sampling. parola italiana più lunga
