SpacTor-T5: Pre-training T5 Models with Span Corruption and Replaced Token Detection

no code implementations24 Jan 2024 Ke Ye, Heinrich Jiang, Afshin Rostamizadeh, Ayan Chakrabarti, Giulia Desalvo, Jean-François Kagy, Lazaros Karydas, Gui Citovsky, Sanjiv Kumar

In this paper, we present SpacTor, a new training procedure consisting of (1) a hybrid objective combining span corruption (SC) and token replacement detection (RTD), and (2) a two-stage curriculum that optimizes the hybrid objective over the initial $\tau$ iterations, then transitions to standard SC loss.
