    Oct 04, 2019 Some notes on the code: input_shape—we only have to give it the shape (dimensions) of the input on the first layer.It’s (8,) since it’s a vector of 8 features. In other words its 8 x 1. Dense—to apply the activation function over ((w • x) + b).The first argument in the Dense function is the number of hidden units, a parameter that you can adjust to improve the

    Oct 01, 2020 MilkyWay001, You have chosen to use sklearn wrappers for your model - they have benefits, but the model training process is hidden. Instead, I trained the model separately with validation dataset added. The code for this would be: clf_1 = KerasClassifier(build_fn=build_fn, n_feats=n_feats) clf_1.fit(Xtrain, ytrain
