### Is there any relationship between the batch size and the number of epochs?

I am currently running a program with a batch size of 17 instead of batch size 32. The benchmark results are obtained at a batch size of 32 with the number of epochs 700. Now I am running with batch ...

### How do you handle skewed image data?

I have an image data-set which I am training a CNN on. The Data-set is slightly skewed. So my solution up till now was to delete some images of the majority class. But I now realize that there are ...

### In a binary classification with CNNs features perform well by themselves, but performance degrades when features are used simultaneously for training

I am doing a binary classification with U-Net. When I use elevation as a feature to train my data the test set performs very well. When I use slope as a feature it performs really well. When I use ...
