How to get a smooth ROC curve from CNN with keras functional API?
I use the following code:
fpr, tpr, t = roc_curve(true_categories, predicted_categories)
I know the predicted_categories should be probability or confidence.
But as predict_proba() seems not working for keras Functional API, how should I get the…

Keras functional API doesn't create any layers on google colab (model.summary() prints no layer)
Problem Summarization
I created keras model using functional API without any error.
But when I call the model.summary(), there is not any layers but only parameters exists.
When I call the model.layers, empty list is returned.
For example, I created…

Tensorflow model architecture for sparse dataset
I have a regression dataset where approximately 95% of the target variables are zeros (the other 5% are between 1 and 30) and I am trying to design a Tensorflow model to model that data. I am thinking of implementing a model that combines a…

How to build a model having multiple inputs and a single output using Keras
I am trying to use the functional api of Keras to build a model having multiple inputs and a single output.
The goal is to combine each row of each input to predict the corresponding output (either 1 or 0).
for example concatenate(inputs_1[0], and…
