For any given learning task, how to select the width and depth of the neural network?
For any given learning task, if I know the nature of dependence to be learnt, how to select the width and depth of the neural network? How does the number of ground truths affect this? Let's say I ...

What loss function to choose that will assign a higher penalty to false negatives than to false positives for regression task?
I am using a machine learning model to remove interference from range-doppler maps to detect targets. I am using a supervised approach, in which I give as input the range-doppler map of target+...

Predict more elements than the input
I can use any machine learning algorithms (but neural networks are better for me) to resolve this issue: use few elements as input (numerical) to predict more elements as output. In normal regression ...
