Web5 apr. 2024 · Fig.2 Bias-variance trade-off diagram (Img created by Author) To implement K-fold cross-validation, we use a scikit_learn wrapper in Keras: KerasClassifier.Specifically, we use Keras to build the model and use scikit_learn for cross-validation. First thing is to build a function for the model architecture as the function is a required argument for the … Web2.3 Defining and training the neural net classifier. We use KerasClassifier because we're dealing with a classifcation task. The first argument should be a callable returning a Keras.Model, in this case, get_clf.As additional arguments, we pass the number of loss function (required) and the optimizer, but the later is optional.
