This is redundant, since the model is always created on fit. Further, `set_tunable_parameters` may be called before `fit` but proper initialization is only guaranteed after the first call to `fit`.
The scikit-learn estimator API stipulates that __init__ should only store its parameters and do no validation (since parameters can later be overridden in set_parameters). Parameters need to be validated on use. https://scikit-learn.org/stable/developers/develop.html#random-numbers

Description
Part of #94 and #116.
Motivation and Context
The scikit-learn estimator API requires us to store all
__init__parameters unmodified. Validation should be delayed as late as possible. That is becauseset_paramscould override those parameters. See https://scikit-learn.org/stable/developers/develop.html#random-numbers.I'm using the pattern of setting
self.random_state_at the beginning of every fit function. In theory that is not always needed, since often the random state is only used in one function. I think its less error-prone to always do it the same way though.How Has This Been Tested?
Ran the pre-commit hooks and the test-suite.
Does this close/impact existing issues?
#94 and #116
