What is structbert-large?
StructBERT is an advanced language model that extends the BERT architecture by incorporating language structures during pre-training. Developed by researchers at Alibaba's AliceMind team, this model specifically focuses on leveraging both word-level and sentence-level language structures to enhance natural language understanding tasks.
Implementation Details
The model implements two auxiliary pre-training tasks that make use of sequential word order and sentence relationships. With 340M parameters, it follows the BERT-large architecture while introducing structural modifications that have led to improved performance on various NLP benchmarks.
- Incorporates word and sentence-level structure learning
- Achieves state-of-the-art results on GLUE benchmark tasks
- Supports both English and Chinese language variants
- Implements PyTorch framework with optional NVIDIA Apex optimization
