Reference score145,000Provisional editorial estimate of this exact contribution; its grade is assessed separately.

What changed

Warmstarts structured Bayesian configuration search using related-dataset meta-features and constructs an ensemble from previously evaluated models in a scikit-learn pipeline search space.

Scientific scope

Warmstarts structured Bayesian configuration search using related-dataset meta-features and constructs an ensemble from previously evaluated models in a scikit-learn pipeline search space. CASH optimization, SMAC, meta-learning and greedy ensemble selection have inherited precedents; this is their system-level integration/extension, not invention of each ingredient. Fixed pipeline choices, datasets and resource budgets bound the evidence.
