class DistilBertEmbeddings extends AnnotatorModel[DistilBertEmbeddings] with HasBatchedAnnotate[DistilBertEmbeddings] with WriteTensorflowModel with HasEmbeddingsProperties with HasStorageRef with HasCaseSensitiveProperties

DistilBERT is a small, fast, cheap and light Transformer model trained by distilling BERT base. It has 40% less parameters than bert-base-uncased, runs 60% faster while preserving over 95% of BERT's performances as measured on the GLUE language understanding benchmark.

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

val embeddings = DistilBertEmbeddings.pretrained()
  .setInputCols("document", "token")
  .setOutputCol("embeddings")

The default model is "distilbert_base_cased", if no name is provided. For available pretrained models please see the Models Hub.

For extended examples of usage, see the Spark NLP Workshop and the DistilBertEmbeddingsTestSpec. Models from the HuggingFace 🤗 Transformers library are also compatible with Spark NLP 🚀. The Spark NLP Workshop example shows how to import them https://github.com/JohnSnowLabs/spark-nlp/discussions/5669.

The DistilBERT model was proposed in the paper DistilBERT, a distilled version of BERT: smaller, faster, cheaper and lighter.

Paper Abstract:

As Transfer Learning from large-scale pre-trained models becomes more prevalent in Natural Language Processing (NLP), operating these large models in on-the-edge and/or under constrained computational training or inference budgets remains challenging. In this work, we propose a method to pre-train a smaller general-purpose language representation model, called DistilBERT, which can then be fine-tuned with good performances on a wide range of tasks like its larger counterparts. While most prior work investigated the use of distillation for building task-specific models, we leverage knowledge distillation during the pretraining phase and show that it is possible to reduce the size of a BERT model by 40%, while retaining 97% of its language understanding capabilities and being 60% faster. To leverage the inductive biases learned by larger models during pretraining, we introduce a triple loss combining language modeling, distillation and cosine-distance losses. Our smaller, faster and lighter model is cheaper to pre-train and we demonstrate its capabilities for on-device computations in a proof-of-concept experiment and a comparative on-device study.

Tips:

  • DistilBERT doesn't have :obj:token_type_ids, you don't need to indicate which token belongs to which segment. Just separate your segments with the separation token :obj:tokenizer.sep_token (or :obj:[SEP]).
  • DistilBERT doesn't have options to select the input positions (:obj:position_ids input). This could be added if necessary though, just let us know if you need this option.

val embeddings = DistilBertEmbeddings.pretrained()

  .setCaseSensitive(true)

val embeddingsFinisher = new EmbeddingsFinisher()
