[2105.00377] MathBERT: A Pre-Trained Model for Mathematical ...
arxiv.org › abs › 2105May 02, 2021 · Large-scale pre-trained models like BERT, have obtained a great success in various Natural Language Processing (NLP) tasks, while it is still a challenge to adapt them to the math-related tasks. Current pre-trained models neglect the structural features and the semantic correspondence between formula and its context. To address these issues, we propose a novel pre-trained model, namely ...
