- Abstract: We consider the task of self-supervised representation learning (SSL) for
tabular data: tabular-SSL. Typical contrastive learning based SSL methods
require instance-wise data augmentations which are difficult to design for
unstructured tabular data. Existing tabular-SSL methods design such
augmentations in a relatively ad-hoc fashion and can fail to capture the
underlying data manifold. Instead of augmentations based approaches for
tabular-SSL, we propose a new reconstruction based method, called Masked
Encoding for Tabular Data (MET), that does not require augmentations. MET is
based on the popular MAE approach for vision-SSL [He et al., 2021] and uses two
key ideas: (i) since each coordinate in a tabular dataset has a distinct
meaning, we need to use separate representations for all coordinates, and (ii)
using an adversarial reconstruction loss in addition to the standard one.
Empirical results on five diverse tabular datasets show that MET achieves a new
state of the art (SOTA) on all of these datasets and improves up to 9% over
current SOTA methods. We shed more light on the working of MET via experiments
on carefully designed simple datasets.
