On the Importance of Hyperparameters and Data Augmentation for Self-Supervised Learning

no code implementations16 Jul 2022 Diane Wagner, Fabio Ferreira, Danny Stoll, Robin Tibor Schirrmeister, Samuel Müller, Frank Hutter

Self-Supervised Learning (SSL) has become a very active area of Deep Learning research where it is heavily used as a pre-training method for classification and other tasks.

TabPFN: A Transformer That Solves Small Tabular Classification Problems in a Second

6 code implementations5 Jul 2022 Noah Hollmann, Samuel Müller, Katharina Eggensperger, Frank Hutter

We present TabPFN, a trained Transformer that can do supervised classification for small tabular datasets in less than a second, needs no hyperparameter tuning and is competitive with state-of-the-art classification methods.

Transformers Can Do Bayesian Inference

1 code implementation ICLR 2022 Samuel Müller, Noah Hollmann, Sebastian Pineda Arango, Josif Grabocka, Frank Hutter

Our method restates the objective of posterior approximation as a supervised classification problem with a set-valued input: it repeatedly draws a task (or function) from the prior, draws a set of data points and their labels from it, masks one of the labels and learns to make probabilistic predictions for it based on the set-valued input of the rest of the data points.

Robust techniques for polarization and detection of nuclear spin ensembles

1 code implementation5 Jun 2017 Jochen Scheuer, Ilai Schwartz, Samuel Müller, Qiong Chen, Ish Dhand, Martin B. Plenio, Boris Naydenov, Fedor Jelezko

Here we demonstrate the polarization and read out of a nuclear spin bath consisting of $^{13}$C nuclear spins in diamond by using a single nitrogen-vacancy (NV) center.
