TL;DR: A table representation method that produces query agnostic embeddings
Abstract: We propose RoTaR, a row-based table representation learning method, to address the efficiency and scalability issues faced by existing table representation learning methods. The key idea of RoTaR is to generate query-agnostic row representations that could be re-used via query-specific aggregation. In addition to the row-based architecture, we introduce several techniques: cell-aware position embedding, AutoEncoder objective in transformer models, teacher-student training paradigm, and selective backward to improve the performance of RoTaR model.
