XlnetEmbeddings (XLNet): Generalized Autoregressive Pretraining for Language Understanding

XLNet is a new unsupervised language representation learning method based on a novel generalized permutation language modeling objective. Additionally, XLNet employs Transformer-XL as the backbone model, exhibiting excellent performance for language tasks involving long context. Overall, XLNet achieves state-of-the-art (SOTA) results on various downstream language tasks including question answering, natural language inference, sentiment analysis, and document ranking.

These word embeddings represent the outputs generated by the XLNet models.

Note that this is a very computationally expensive module compared to word embedding modules that only perform embedding lookups. The use of an accelerator is recommended.

"xlnet_large_cased" = XLNet-Large \| 24-layer, 1024-hidden, 16-heads

"xlnet_base_cased" = XLNet-Base \| 12-layer, 768-hidden, 12-heads. This model is trained on full data (different from the one in the paper).

Pretrained models can be loaded with pretrained of the companion object:

val embeddings = XlnetEmbeddings.pretrained()
  .setInputCols("sentence", "token")
  .setOutputCol("embeddings")

The default model is "xlnet_base_cased", if no name is provided.

For extended examples of usage, see the Examples and the XlnetEmbeddingsTestSpec. To see which models are compatible and how to import them see https://github.com/JohnSnowLabs/spark-nlp/discussions/5669.

XLNet: Generalized Autoregressive Pretraining for Language Understanding

https://github.com/zihangdai/xlnet

Paper abstract:

With the capability of modeling bidirectional contexts, denoising autoencoding based pretraining like BERT achieves better performance than pretraining approaches based on autoregressive language modeling. However, relying on corrupting the input with masks, BERT neglects dependency between the masked positions and suffers from a pretrain-finetune discrepancy. In light of these pros and cons, we propose XLNet, a generalized autoregressive pretraining method that (1) enables learning bidirectional contexts by maximizing the expected likelihood over all permutations of the factorization order and (2) overcomes the limitations of BERT thanks to its autoregressive formulation. Furthermore, XLNet integrates ideas from Transformer-XL, the state-of-the-art autoregressive model, into pretraining. Empirically, under comparable experiment settings, XLNet outperforms BERT on 20 tasks, often by a large margin, including question answering, natural language inference, sentiment analysis, and document ranking.
