How to export a Deep Learning model trained with Keras in DSS?
Hi, I have spent many weeks collecting, sampling and preprocessing data. I have finally trained a model that suits my purpose however i was rudely awakened by my inability to export the model outside DSS. Are models trained in DSS not exportable? I can find the keras_model.h5 file however no model.json. Is there anyway i…

How to get Variable Importance from Model
Hi, I want to automatically consume the data on the "Variable Importance" area under the "Interpretation" section of a trained model. I see that I can manually export this data, but what I am trying to do is to get this data in a dataset or something similar where I can build pipelines on top of it. Is that possible?

Imbalanced dataset split policy
Hi, about the "explicit extract from dataset" policy on the "train & validation" setting page. I would like to be able to train a classification model with a balanced training set and run the test with an original (unbalanced) distribution test set. However, I realized that the records used for the training set are not…
