Args:
optimize_strategy (str, default "auto_strategy"):
The strategy to train logistic regression models. Possible values are
"auto_strategy", "batch_gradient_descent", "normal_equation". Default
to "auto_strategy".
"auto_strategy" and "batch_gradient_descent". The two are equilevant since
"auto_strategy" will fall back to "batch_gradient_descent". The API is kept
for consistency.
Default to "auto_strategy".
fit_intercept (default True):
Default True. Specifies if a constant (a.k.a. bias or intercept)
should be added to the decision function.
