SAINT: feature and intersample attention with tabular pretraining

What changed

Embedded categorical and continuous columns, combined within-row self-attention with attention across rows in a batch, and studied contrastive plus denoising pretraining with mixed data views.

Scientific scope

Embedded categorical and continuous columns, combined within-row self-attention with attention across rows in a batch, and studied contrastive plus denoising pretraining with mixed data views. Intersample attention depends on the batch/context rows; it is not an isolated-row predictor with no cross-sample cost. Transformer attention, CutMix/mixup and contrastive objectives are inherited. Tested task averages do not establish superiority over boosting for every table or medical application.
