    In hindsight, the Prior Labs exit to SAP couldn't have been timed better.

      They don't show the strongest TabPFN variants in the plot unfortunately, i.e. thinking and ensembled. Not really apples to apples.

    150,000 rows of data, where will I store it all?!

      The biggest misconception that people have when modeling using tabular data is that more data = better model.

      Big Data is terrifying and only solvable with opaque deep learning

      You don't need to. Just sample 1% of data, let the model do the feature engineering, ask model model to replicate everything in Pandas (or R, or whatever else), so you can run it for a full dataset.

    On the one hand, this is impressive. TabPFN was already state of the art and is seriously shaking up Bayesian prediction for tabular data (which is almost everything).

    On the other hand, perhaps it is just me, but I do not feel that this is an acceptable form of benchmark reporting in this domain. TabArena actually has multiple metrics, since ELO does not properly quantify the degree of improvement. The fact that these are not displayed here should give pause. Also the results section in the GitHub is a dumpster fire.

      GitHub Repo: Please see the results folder

      Results folder: Here's some undocumented parquet files

      Definitely feels like they're hiding the ball lol.

      If they had good benchmarks they'd talk about them.

      Not comparing to tuned xgboost is also a warning sign.

        wouldn't xgboost be covered under autogluon? not perfect, but not missing either

        • Eridrus 2 days ago ago

          Honestly, I don't really know AutoGluon, if this does xgboost tuning that's good.

          I do still think ELO scores are still a way to obscure results though. For all we know this is like 0.1% better than a "normal" approach on like 70% of tasks and a tire fire on others.

          • nok22kon 2 days ago ago

            AutoGluon does their own benchmarking, the default is Elo, but you can switch to other metrics:

            https://huggingface.co/spaces/TabArena/leaderboard

            xgboost is listed, they say "tuned" but who knows what that means. and its below CatBoost and LightGBM

            as an aggregator of models (trees, neural networks, clustering, ...) AutoGluon doesn't really have a dog in this fight

              Thanks for the pointer, though I can't seem to find TabFM and AutoGluon at that link?

    interesting to see this from Google after the SAP acquisition of Prior Labs.
