SAVRN's Notes on mdeberta-v3-base

Not everything worth running generates text. mdeberta-v3-base fills in masked tokens: an encoder from Microsoft with 12 layers, a 251,000-entry vocabulary and a 512-token window, meant to be fine-tuned for downstream language understanding. We have no run figures for it on the Index yet, but the weights come to just under 3.4 GB across nine files in PyTorch and TensorFlow formats, small enough that the question is how many copies share one accelerator.

MIT is about as short as a license gets: commercial use, modification and redistribution, provided the copyright and permission notices ride along, so a fine-tuned derivative ships inside a product. Plan around two things. The 512-token window is a hard ceiling per input, so long documents get chunked before they reach it. And the weights have not changed since April 2023, so the two papers behind them, arXiv:2006.03654 and arXiv:2111.09543, describe what you get.

DeBERTaV3: Improving DeBERTa using ELECTRA-Style Pre-Training with Gradient-Disentangled Embedding Sharing

DeBERTa improves the BERT and RoBERTa models using disentangled attention and enhanced mask decoder. With those two improvements, DeBERTa out perform RoBERTa on a majority of NLU tasks with 80GB training data.

In DeBERTa V3, we further improved the efficiency of DeBERTa using ELECTRA-Style pre-training with Gradient Disentangled Embedding Sharing. Compared to DeBERTa, our V3 version significantly improves the model performance on downstream tasks. You can find more technique details about the new model from our paper.

Please check the official repository for more implementation details and updates.

Bio_ClinicalBERT

Emily Alsentzer

The Publicly Available Clinical BERT Embeddings paper contains four unique clinicalBERT models: initialized with BERT-Base (casedL-12H-768A-12) or BioBERT (BioBERT-Base v1.0 + PubMed 200K + PMC 270K) & trained on either all MIMIC notes or only discharge summaries. This model card describes the Bio+Clinical BERT model, which was initialized from BioBERT & trained on all MIMIC notes. The BioClinicalBERT model was trained on all notes from MIMIC III, a database containing electronic health records from ICU patients at the Beth Israel Hospital in Boston, MA. For more details on MIMIC, see here. All notes from the NOTEEVENTS table were included (~880M words). Each note in MIMIC was first split…

This model was previously named "PubMedBERT (abstracts)". You can either adopt the new model name "microsoft/BiomedNLP-BiomedBERT-base-uncased-abstract" or update your transformers library to version 4.22+ if you need to refer to the old name. Pretraining large neural language models, such as BERT, has led to impressive gains on many natural language processing (NLP) tasks. However, most pretraining efforts focus on general domain corpora, such as newswire and Web. A prevailing assumption is that even domain-specific pretraining can benefit by starting from general-domain language models. Recent work shows that for domains with abundant unlabeled text, such as biomedicine, pretraining…
