Weโre happy to announce our first release in relational learning at Prior Labs, continuing our commitment to open science.
We open-source three pieces of software that we expect to accelerate research in the field towards meaningful, real-world impact.
First and foremost, we release ๐ฅ๐ฒ๐น๐๐ฟ๐ฒ๐ป๐ฎ-ฮฑ: a unified framework for running and comparing baselines on RelBench v1 tasks. Based on learnings from tabular benchmarks like TabArena, we are standardizing data loading, evaluation protocols, tuning regimes, and adding support for systems with custom tuning.
We also open-source ๐ง๐ฎ๐ฏ๐ฃ๐๐ก-๐ฅ๐ฒ๐น: our relational harness for TabPFN-3. We initialize the (living) RelArena-ฮฑ leaderboard with TabPFN-Rel and a comprehensive set of baselines. The rankings at the time of release are:
โข ๐ง๐ฎ๐ฏ๐ฃ๐๐ก-๐ฅ๐ฒ๐น is the No. 1 model submission
โข ๐ฅ๐ง-๐ฃ๐น๐๐ฅ๐ฒ๐น is the No. 1 system submission
Last but not least, we open-source an alpha version of the ๐ฅ๐ฒ๐น๐ฎ๐๐ถ๐ผ๐ป๐ฎ๐น ๐ฃ๐ฟ๐ฒ๐ฑ๐ถ๐ฐ๐๐ถ๐๐ฒ ๐๐ป๐๐ฒ๐ฟ๐ณ๐ฎ๐ฐ๐ฒ (๐ฅ๐ฃ๐): enabling you to easily specify prediction tasks on your own relational database and then run any RelArena-ฮฑ model, like TabPFN-Rel, in a few lines of code, all bundled as a simple PyPI package.
