## Overview
|
||||
|
||||
The XLM-ProphetNet model was proposed in [ProphetNet: Predicting Future N-gram for Sequence-to-Sequence Pre-training,](https://huggingface.co/papers/2001.04063) by Yu Yan, Weizhen Qi, Yeyun Gong, Dayiheng Liu, Nan Duan, Jiusheng Chen, Ruofei
|
||||
Zhang, Ming Zhou on 13 Jan, 2020.
|
||||
|
||||
XLM-ProphetNet is an encoder-decoder model and can predict n-future tokens for "ngram" language modeling instead of
|
||||
just the next token. Its architecture is identical to ProhpetNet, but the model was trained on the multi-lingual
|
||||
"wiki100" Wikipedia dump. XLM-ProphetNet's model architecture and pretraining objective is same as ProphetNet, but XLM-ProphetNet was pre-trained on the cross-lingual dataset XGLUE.
|
||||
|
||||
The abstract from the paper is the following:
|
||||
|
||||
*In this paper, we present a new sequence-to-sequence pretraining model called ProphetNet, which introduces a novel
|
||||
self-supervised objective named future n-gram prediction and the proposed n-stream self-attention mechanism. Instead of
|
||||
the optimization of one-step ahead prediction in traditional sequence-to-sequence model, the ProphetNet is optimized by
|
||||
n-step ahead prediction which predicts the next n tokens simultaneously based on previous context tokens at each time
|
||||
step. The future n-gram prediction explicitly encourages the model to plan for the future tokens and prevent
|
||||
overfitting on strong local correlations. We pre-train ProphetNet using a base scale dataset (16GB) and a large scale
|
||||
dataset (160GB) respectively. Then we conduct experiments on CNN/DailyMail, Gigaword, and SQuAD 1.1 benchmarks for
|
||||
abstractive summarization and question generation tasks. Experimental results show that ProphetNet achieves new
|
||||
state-of-the-art results on all these datasets compared to the models using the same scale pretraining corpus.*
