Deductive Logic in Language Models: Horizontal vs Vertical Reasoning

📰 ArXiv cs.AI

Learn how language models use horizontal and vertical reasoning for deductive logic and why it matters for AI development

advanced Published 1 Jul 2026
Action Steps
  1. Train a small transformer-based language model from scratch on multi-step deductive tasks
  2. Configure the model to use horizontal reasoning with autoregressive intermediate steps
  3. Test the model's performance on deductive inference tasks using vertical reasoning with implicit layer unfolding
  4. Apply the insights from the comparison to improve the model's logical reasoning abilities
  5. Run experiments to evaluate the effectiveness of different reasoning mechanisms
Who Needs to Know This
