What is PhoBERT-base-v2?
PhoBERT-base-v2 is an advanced Vietnamese language model that builds upon the success of the original PhoBERT architecture. Based on RoBERTa optimization of BERT, this model represents a significant breakthrough in Vietnamese natural language processing. It's trained on an extensive dataset of 140GB, combining 20GB of Wikipedia and news texts with 120GB from OSCAR-2301, making it one of the most comprehensively trained Vietnamese language models available.
Implementation Details
The model implements a RoBERTa-based architecture with 135M parameters, designed specifically for Vietnamese language understanding. It requires word-segmented input and integrates seamlessly with the Hugging Face transformers library. The model supports both PyTorch and TensorFlow 2.0+ implementations.
