This PR removes explicit
multi_class="multinomial"arguments fromLogisticRegression usage in examples / notebooks / tests.
In sklearn ≥ 1.5 the
multi_classparameter is deprecated and will beremoved in 1.7. The default behavior is now always
multinomial, soremoving this avoids FutureWarning while keeping identical behavior.
✓ verified on sklearn ≥ 1.6
✓ warnings disappear
✓ outputs unchanged
Note: usages with
multi_class="ovr"were intentionally left unchangedto avoid altering behavior.
Closes #1126
