Classification task on boolean only features: what model/layers/activators are better?

Most architecture rely on float operations as the optimisation process requires to work with a continum of values. If you want to solve for parameters than can only take discrete values, then it's not ...

CNN model with images - 100% accuracy on validation and test sets with limited data?

Taking 207 images made from 7 videos, and then randomly forming train and validation sets can lead to a massive data leakage: both train and validation sets will have many images from every video. For ...

Keras single sample prediction returns different values

I do not how to fix this in a correct manner, but it seems the reason is because the model was trained on batches rather than individual examples. My model is also based on ResNet50 (a part of it) and ...
