"Forest-of-Thought: Scaling Test-Time Compute for Enhancing LLM Reasoning"

The podcast on this paper is generated with Google's Illuminate.

Multiple reasoning trees working together make LLMs think better than single-tree approaches.

Forest-of-Thought framework integrates multiple reasoning trees with sparse activation and self-correction to enhance LLM reasoning capabilities beyond single-pass approaches.

🤔 Original Problem:

→ Current LLM reasoning methods like Chain-of-Thought and Tree-of-Thought perform only single-pass reasoning, leading to flawed paths and compromised accuracy.

-----

🌳 Solution in this Paper:

→ Forest-of-Thought (FoT) creates multiple independent reasoning trees to approach problems from different angles.

→ Sparse activation strategies select only the most relevant reasoning paths, optimizing both efficiency and accuracy.

→ Dynamic self-correction enables real-time error detection and correction during reasoning.

→ Consensus-guided expert decision making optimizes correctness and computational resource usage.

-----

🔍 Key Insights:

→ Multiple reasoning trees provide better collective decision-making than single-tree approaches

→ Sparse activation significantly improves computational efficiency

→ Self-correction mechanism prevents error propagation across reasoning steps

→ Consensus-guided decisions outperform random and score-based selection

-----

📊 Results:

→ FoT with 4 trees achieved 91.58% accuracy on Game of 24 tasks vs 74.74% for single-tree ToT

→ Dynamic self-correction improved accuracy by 5% for zero-shot-CoT and over 50% for ToT

→ CGED selection strategy outperformed random and score-based selection by 0.8-0.9% accuracy
