Web14 apr. 2024 · Anyway, designing fine-tuning tasks for pretrained language models that encourage cooperation with other modules to improve the performance of math word problem solvers is an unaddressed problem. To solve these problems, in this paper we propose a BERT-based model for solving math word problems with a supervision module. Web15.10.1. Pretraining BERT. The original BERT has two versions of different model sizes ( Devlin et al., 2024). The base model ( BERT BASE) uses 12 layers (Transformer encoder blocks) with 768 hidden units (hidden size) and 12 self-attention heads. The large model ( BERT LARGE) uses 24 layers with 1024 hidden units and 16 self-attention heads.
