About this paper
Artit Wangperawong
This research demonstrates that Transformer neural networks can learn to evaluate mathematical expressions, including operations with symbolic variables and negative numbers, directly from character-level input. The Adaptive Universal Transformer achieved 84.9% accuracy on a diverse dataset of arithmetic problems, showing strong performance on addition and subtraction while highlighting challenges in multiplication.
Key insights
- Transformer architectures, especially with enhancements like recurrence and adaptive computation time, can acquire an emergent understanding of mathematical syntax and semantics directly from character-level data.
- The models successfully learned to bind and utilize symbolic variables, demonstrating robust variable manipulation even with randomized input orders.
- Mathematical computation serves as a simplified, structured proxy for natural language understanding, suggesting that insights gained here could inform more complex NLU and question-answering systems.
