jakirkham 6ce497c3bc [MRG] ENH: Optional positivity constraints on the dictionary and sparse code (#6374)
* ENH: Add positivity option for code and dictionary

Provides an option for dictionary learning to positively constrain the
dictionary and the sparse code. This is useful in applications of
dictionary learning where the data is know to be positive (e.g. images),
but the sparsity constraint that dictionary learning has is better
suited for factorizing the data in contrast to other positively
constrained factorization techniques like NMF, which may not be
similarly sparse.

* TST: Test positivity with code and dictionary

Ensure that when the positivity constraint is applied that the
dictionary and code end up having only positive values in the respective
results depending on whether dictionary and/or code are positively
constrained.

* DOC: Positivity constraints dictionary learning

Shows the various positivity constraints on dictionary learning and what
the results of these look like using a Red to Blue color map. These are
included in the examples and also in the docs below dictionary learning.
All of these use the Olivetti faces as a training set.

Igor Andriushchenko 9b5610415b [MRG] Add Deprecation Warning to address making "batch" the default learning method in LDA in 0.19 release (#6999)
* update default LDA method to batch

* update tests to match default LDA learning scheme

* DOC trim information on faster learning scheme with LDA

* Add deprecation warning and revert learning_method back to the default

After the discussion, it was decided that a proper deprecation cycle
for the parameter is required. Therefore, in this PR only the warning is
added. The default learning_method will be changed to 'batch' in 0.19.

* Revert back tests to the default LDA

* DOC deprecate in 0.20 instead of 0.19
