'Is it possible to mask individual features in tensorflow?
I have a large quantity of missing values that appear at random in my data. Unfortunately, I cannot simply drop observations with missing data as I am grouping observations by a feature and cannot drop NaNs without affecting the entire group.
I was hoping to simply mask features that were missing. So a single group might have 8 items in it, and each item may have 0 to N features, depending on how many got masked due to being missing.
I have been experimenting a lot with RaggedTensors, but have encountered a lot of issues ranging from not being able to flatten the RaggedTensor, not being able to concatenate it with regular tensors of uniform shape, and Dense layers requiring the last dimension of their input to be known, aka the number of features.
Does anybody know if there is a way to do this?
