Validate activity before betting a new project on holodeck. ## Common questions ### What is the difference between auto-sklearn and holodeck? auto-sklearn: Automated Machine Learning with scikit-learn. holodeck: High Fidelity Simulator for Reinforcement Learning and Robotics Research.. See the comparison table for live GitHub stats and shared categories. ### When should I choose auto-sklearn over holodeck? Choose auto-sklearn over holodeck when License: auto-sklearn is BSD-3-Clause, holodeck is MIT; Tags unique to auto-sklearn: automated-machine-learning, automl, bayesian-optimization, hyperparameter-optimization; Also covers Developer Tools, Model Training; auto-sklearn ships Docker support for self-hosted deployment. ### When should I choose holodeck over auto-sklearn? Choose holodeck over auto-sklearn when License: holodeck is MIT, auto-sklearn is BSD-3-Clause; Tags unique to holodeck: ai, computer-vision, drones, reinforcement-learning; Leaner open-issue backlog (52). ### When should I avoid auto-sklearn? Developer Tools: A gateway is overkill when you're pinned to a single provider and model. Model Training: Try prompting and RAG first; fine-tuning is the answer to style/format, not missing knowledge. ### When should I avoid holodeck? Last GitHub push was 1604 days ago (dormant maintenance, Feb 19, 2022). Validate activity before betting a new project on holodeck. ### Is auto-sklearn or holodeck more popular on GitHub? auto-sklearn has more GitHub stars (8,119 vs 596). Stars measure visibility, not whether either tool fits your constraints. ### Are auto-sklearn and holodeck open source? Yes - both are open-source projects on GitHub (auto-sklearn: BSD-3-Clause, holodeck: MIT). ### Where can I find alternatives to auto-sklearn or holodeck? GraphCanon lists graph-backed alternatives at [auto-sklearn alternatives](/tools/automl-auto-sklearn/alternatives) and [holodeck alternatives](/tools/byu-pccl-holodeck/alternatives) ([auto-sklearn markdown twin](/tools/automl-auto-sklearn/alternatives.md), [holodeck markdown twin](/tools/byu-pccl-holodeck/alternatives.md)), ranked by typed relationship edges rather than popularity votes. ### Is there a machine-readable version of this comparison? Yes. The markdown twin at [this comparison](/compare/automl-auto-sklearn-vs-byu-pccl-holodeck.md) mirrors this page for agents and LLM crawlers, with the same stats table and FAQ answers. ### Which is better maintained, auto-sklearn or holodeck? auto-sklearn: Active. holodeck: Dormant. Compare maintenance labels, days since push, and release cadence in the trust section below - stars alone do not measure maintenance. ### Where are the full trust reports for auto-sklearn and holodeck? GraphCanon publishes per-repo trust reports with dated maintenance, provenance, and scan summaries: [auto-sklearn trust report](/tools/automl-auto-sklearn/trust); [holodeck trust report](/tools/byu-pccl-holodeck/trust). --- **Machine-readable endpoints** - JSON: [`/api/graphcanon/graph?tool=automl-auto-sklearn`](/api/graphcanon/graph?tool=automl-auto-sklearn) - LLM index: [/llms.txt](/llms.txt) - Full corpus: [/llms-full.txt](/llms-full.txt) _GraphCanon - The knowledge graph for AI development. https://www.graphcanon.com/_
