On the other hand, in tabular learning settings, both pretext and downstream tasks are supervised learning tasks on columns. We expect the decoder is more likely to learn the knowledge beneficial for the downstream task in the fine-tuning phase.

Webbpretext task confide in the heuristics of designing the pretext task that limits the generalization of learned representations. The discriminative approach in the form of contrastive learning is utilized to learn the latent representation to overcome the heuristics of pretext tasks [14] [15].

In contrast, we introduce a self-supervised task that is much closer to detection and show the benefits of combining self-supervised learning with classification pre-training.
