  "title": "TabPack: Efficient Hyperparameter Ensembles for Tabular Deep Learning",
  "why_included": "TabPack trains many MLPs with sampled hyperparameters in one run and picks ensemble members on the fly, matching tuned tabular baselines out of the box — a default MacBook run beat some baselines' GPU tuning time.",
  "summary": "**The gist** **TabPack** is an MLP ensemble for tabular deep learning that, in a **single run**, samples and trains many MLPs with different hyperparameters in parallel and selects ensemble members on the fly during training. You supply hyperparameter **ranges** instead of exact values; on medium-to-large public datasets, defaults match extensively tuned prior methods.",
  "practical_implication": "**Why it matters** Off the agent path, but handy if your product carries a tabular ML component: it removes the tuning loop that dominates tabular deep-learning cost. The authors report the **default configuration on a modern MacBook** finished in less time than tuning some baselines took on an **industry-grade GPU** — cheap enough to fold into a local pipeline.",
