A Simple Baseline for Predicting Events with Auto-Regressive Tabular Transformers

1 code implementation14 Oct 2024 Alex Stein, Samuel Sharpe, Doron Bergman, Senthil Kumar, C. Bayan Bruss, John Dickerson, Tom Goldstein, Micah Goldblum

Moreover, these approaches often assume specific use-cases, for example that we know the labels of all historic events or that we only predict a pre-specified label and not the data's features themselves.

Just How Flexible are Neural Networks in Practice?

no code implementations17 Jun 2024 Ravid Shwartz-Ziv, Micah Goldblum, Arpit Bansal, C. Bayan Bruss, Yann Lecun, Andrew Gordon Wilson

Our findings indicate that: (1) standard optimizers find minima where the model can only fit training sets with significantly fewer samples than it has parameters; (2) convolutional networks are more parameter-efficient than MLPs and ViTs, even on randomly labeled data; (3) while stochastic training is thought to have a regularizing effect, SGD actually finds minima that fit more training data than full-batch gradient descent; (4) the difference in capacity to fit correctly labeled and incorrectly labeled samples can be predictive of generalization; (5) ReLU activation functions result in finding minima that fit more data despite being designed to avoid vanishing and exploding gradients in deep architectures.

Counterfactual Explanations via Latent Space Projection and Interpolation

no code implementations2 Dec 2021 Brian Barr, Matthew R. Harrington, Samuel Sharpe, C. Bayan Bruss

Counterfactual explanations represent the minimal change to a data sample that alters its predicted classification, typically from an unfavorable initial class to a desired target class.

Multi-Domain Self-Supervised Learning

no code implementations29 Sep 2021 Neha Mukund Kalibhat, Yogesh Balaji, C. Bayan Bruss, Soheil Feizi

In fact, training these methods on a combination of several domains often degrades the quality of learned representations compared to the models trained on a single domain.
