Bumps optuna from 4.6.0 to 4.7.0.

Release notes

Sourced from optuna's releases.

v4.7.0

This is the release note of v4.7.0.

Highlights

Two New Multi-Objective Samplers Added to OptunaHub!

@​hrntsm introduces two new multi-objective samplers—SPEA-II (Strength Pareto Evolutionary Algorithm 2) and HypE (Hypervolume Estimation Algorithm)—to OptunaHub. SPEA-II is an improved multi-objective evolutionary algorithm that differs from NSGA-II in its selection mechanism. HypE is a fast, hypervolume-based evolutionary algorithm designed for many-objective optimization problems. Please refer to the following pages for more details:

PedAnovaImportanceEvaluator Now Supports Local Hyperparameter Importance Computation

The target_quantile and region_quantile arguments have been introduced to PedAnovaImportanceEvaluator. This change allows you to investigate local hyperparameter importance rather than the global one with region_quantile < 1.0. See the original paper for the technical details.

  • Introduce stacklevel-aware custom warnings (#6293)
  • Cache distributions to skip consistency check (#6301)
  • Add warnings when JournalStorage lock acquisition is delayed (#6361)

Documentation

  • Add SECURITY.md (#6317)
  • Add a note for future dev of exclusive HV (#6318)
