viniLM-2021-from-large

Model Info:

Authors: R&D AI Lab, VMware Inc.
Model date: Jun 2022
Model version: 2021-distilled-from-large
Model type: Pretrained language model

Motivation

Based on MiniLMv2 distillation, we have distilled vBERT-2021-large into a smaller minilmv2 model for faster inference times without a significant loss of performance.

Intended Use

The model functions as a VMware-specific Language Model.

How to Use

Here is how to use this model to get the features of a given text in PyTorch:

from transformers import BertTokenizer, BertModel
tokenizer = BertTokenizer.from_pretrained('VMware/vinilm-2021-from-large')
model = BertModel.from_pretrained("VMware/vinilm-2021-from-large")
text = "Replace me by any text you'd like."
encoded_input = tokenizer(text, return_tensors='pt')
output = model(**encoded_input)

and in TensorFlow:

from transformers import BertTokenizer, TFBertModel
tokenizer = BertTokenizer.from_pretrained('VMware/vinilm-2021-from-large')
model = TFBertModel.from_pretrained('VMware/vinilm-2021-from-large')
text = "Replace me by any text you'd like."
encoded_input = tokenizer(text, return_tensors='tf')
output = model(encoded_input)

Training

The model is distilled from vBERT-2021-large
Weights were initialized using nreimers/MiniLMv2-L6-H768-distilled-from-BERT-Large

- Datasets

Publically available VMware text data such as VMware Docs, Blogs, etc. were used for distilling the teacher vBERT-2021-large model into vinilm-2021-from-large model. Sourced in May 2021. (~320,000 Documents)

- Preprocessing

Decoding HTML
Decoding Unicode
Stripping repeated characters
Splitting compound word
Spelling correction

- Model performance measures

We benchmarked vinilm on various VMware-specific NLP downstream tasks (IR, classification, etc).

Limitations and bias

Since the model is distilled from a vBERT model based on the BERT model, it may have the same biases embedded within the original BERT model.

The data needs to be preprocessed using our internal vNLP Preprocessor (not available to the public) to maximize its performance.
