말뭉치

  1. XLNet and RoBERTa improve on the performance while DistilBERT improves on the inference speed.[1]
  2. Importantly, RoBERTa uses 160 GB of text for pre-training, including 16GB of Books Corpus and English Wikipedia used in BERT.[1]
  3. RoBERTa was also trained on an order of magnitude more data than BERT, for a longer amount of time.[2]
  4. Download RoBERTa already finetuned for MNLI roberta = torch .[2]
  5. # Encode a pair of sentences and make a prediction tokens = roberta .[2]
  6. Note that current best models on GLUE such as T5 (11B) do not fit on this plot because they use much more compute than others (around 10x more than RoBERTa).[3]
  7. Facebook AI open-sourced a new deep-learning natural-language processing (NLP) model, robustly-optimized BERT approach (RoBERTa).[4]
  8. In creating RoBERTa, the Facebook team first ported BERT from Google's TensorFlow deep-learning framework to their own framework, PyTorch.[4]
  9. RoBERTa uses dynamic masking, with a new masking pattern generated each time a sentence is fed into training.[4]
  10. Next, RoBERTa eliminated the NSP training, as Facebook's analysis showed that it actually hurt performance.[4]
  11. RoBERTa doesn’t have token_type_ids , you don’t need to indicate which token belongs to which segment.[5]
  12. RoBERTa stands for Robustly Optimized BERT Pre-training Approach.[6]
  13. The network uses the Chinese pre-trained RoBERTa to initialize representation layer parameters.[7]
  14. In this article I want to use text representations extracted from RoBERTa Base model to build a token level binary text classification model based on LSTM units.[8]
  15. This step is important in our example, because we can’t convert all tokens in our dataset to RoBERTa Base feature vectors and store them, then train our model (because of storage limitations).[8]
  16. We will briefly describe its architecture and demonstrate how to use it with an optimized version called RoBERTa.[9]
  17. The Roberta Masked language model is shown in Figure 4 below.[9]
  18. To illustrate the behavior of RoBERTa language model can load an instance as follows.[9]
  19. XLNet is a newer Transformer language model that is showing better performance than BERT or RoBERTa on many test cases.[9]
  20. Facebook has launched its own improvement, RoBERTa, which produced state-of-the-art results on the most popular NLP benchmark known as GLUE.[10]
  21. Big pretrained MLMs like BERT and RoBERTa are the bread and butter of NLP, and clearly have learned a good deal both about English grammar and about the outside world.[11]
  22. The MiniBERTas are a family of models based on RoBERTa that we pretrained with different amounts of data for part of our own ongoing work.[11]
  23. We exactly reproduced RoBERTa pretraining except that we used the pretraining datasets of BERT, we pretrained the models using smaller batch sizes, and that we varied the size of pretraining data.[11]
  24. Our best models pretrained on 1M, 10M, 100M, 1B tokens show validation perplexities of 134.18, 10.78, 4.61, and 3.84, in comparison with RoBERTa-base’s 3.41 and RoBERTa-large’s 2.69.[11]
  25. I personally got the best results from Roberta Model.[12]
  26. previous pretty ALBERT uses 10x more compute than RoBERTa DistilBERT - / 2x 77.[12]
  27. , BERT, RoBERTa, XLNet, AlBERT, and DistilBERT), proposed fusion-based approaches, and compared the developed models with several traditional machine learning, including deep learning, approaches.[12]
  28. RoBERTa is an optimisation of Google’s popular BERT system for pre-training Natural Language Processing (NLP) systems that was open sourced in November last year.[13]
  29. By training longer, on more data, and dropping BERT’s next-sentence prediction, RoBERTa topped the GLUE leaderboard.[13]
  30. This allows RoBERTa to improve on the masked language modeling objective compared with BERT and leads to better downstream task performance.[13]
  31. We also explore training RoBERTa on an order of magnitude more data than BERT, for a longer amount of time.[13]
  32. Roberta studied Bayesian inference and mathematical biology at the University of Glasgow but then decided to leave the academia and become a data scientist.[14]
  33. Google Lab released a new pre-trained model"ALBERT" fully surpassed BERT, XLNet, and Roberta in tasks such as SQuAD 2.0, GLUE, RACE, and refreshed the ranking again![15]
  34. Entwickelt vom Open Roberta Team ...[16]
