Method Standard language modeling learns about a large text corpus x1, . . . xT by implementing a next-token prediction task. Formally, the learning objective is to minimize the cross-entropy loss In this work, we generalize the above by implementing a multi-token prediction task, where at each position of the training corpus, the model is instructed to predict n future tokens at once. This translates into the cross-entropy loss This paper is available on arxiv under CC BY 4.0 DEED license. This paper is available on arxiv under CC BY 4.0 DEED license. available on arxiv Authors:
