Question about estimate_performance()

[ljchang]

I am running estimate_performance() function on sparse data and am curious about how the mask_items keyword argument works.

From docstrings
n_mask_items (int/float, optional): how much randomly sparsify dense data each iteration; Defaults to masking out 20% of observed

This keyword makes sense for dense data, but how does it work with sparse data? is it ignored?

Yup it's ignored. Can clarify this in the documentation
