Web4 de ago. de 2024 · Hyperparameter optimization is a big part of deep learning. The reason is that neural networks are notoriously difficult to configure, and a lot of parameters need to be set. On top of that, individual models can be very slow to train. In this post, you will discover how to use the grid search capability from the scikit-learn Python machine … WebBy default, if you don't specify the hidden layer sizes parameter, Scikit-learn will create a single hidden layer with 100 hidden units. While a setting of 10 may work well for simple datasets like the one we use as examples here, for really complex datasets, the number of hidden units could be in the thousands.
