phobert base

Introduction

PhoBERT is a state-of-the-art pre-trained language model specifically designed for Vietnamese. It comes in two versions, "base" and "large," and is the first public, large-scale, monolingual language model for Vietnamese. PhoBERT's pre-training is based on RoBERTa, enhancing the BERT pre-training procedure for improved performance. It has achieved state-of-the-art results on various Vietnamese NLP tasks, including part-of-speech tagging, dependency parsing, named-entity recognition, and natural language inference.

Architecture

PhoBERT is built on the RoBERTa architecture, which is an optimized version of BERT. RoBERTa improves the training procedures of BERT, making it more robust and effective in diverse tasks. This architecture allows PhoBERT to outperform both monolingual and multilingual models in Vietnamese language processing tasks.

Training

PhoBERT models are pre-trained on a large corpus of Vietnamese text. This comprehensive training allows the model to understand and process Vietnamese language tasks effectively. The two versions of PhoBERT, "base" and "large," differ mainly in their size and the amount of data they are trained on, with the "large" version generally providing better performance due to its larger capacity.

Guide: Running Locally

1. Installation: Ensure that you have Python and the necessary libraries installed, including PyTorch or TensorFlow, whichever is compatible with PhoBERT.
2. Download Model: Obtain the PhoBERT model from the Hugging Face model hub.
3. Load Model: Use the Transformers library to load the PhoBERT model into your local environment.
4. Inference: Run inference on Vietnamese text using the loaded model to perform tasks like tagging or parsing.

Cloud GPUs: For efficient processing, consider using cloud-based GPUs such as those provided by AWS, Google Cloud, or Azure, which can significantly speed up model training and inference.
