Tyler: Typed Latent Reasoning for Language Models -- When to Think, What to Compute, and How Much to Allocate
Summary
Tyler, a novel framework for Typed Latent Reasoning, addresses the challenge of dynamically invoking and allocating latent computation within large language models during autoregressive decoding. Unlike Chain-of-Thought prompting, which uses discrete text tokens, Tyler learns a policy to decide at each step whether to emit a text token or switch to a specialized latent computation module. These modules support functions like global planning, local state updates, or reusable procedural abstraction using latent tokens. Experiments across three backbone LLMs demonstrate Tyler's effectiveness, improving accuracy by up to 14.49 points over CoT and up to 4.30 points over the strongest baseline. It also shows strong generalization across diverse reasoning domains with minimal forgetting.
Key takeaway
For Machine Learning Engineers optimizing LLM reasoning, Tyler presents a compelling alternative to traditional Chain-of-Thought methods. You should explore dynamic latent reasoning frameworks that learn to allocate computation based on task needs. This approach can significantly boost accuracy by up to 14.49 points and enhance generalization, potentially reducing inference overhead compared to text-based reasoning. Consider integrating policy-driven latent computation for complex reasoning tasks.
Key insights
Tyler dynamically manages latent computation in LLMs, deciding when, what type, and how much to allocate for improved reasoning.
Principles
- Latent reasoning can reduce redundancy and inference overhead compared to textual Chain-of-Thought.
- Learning a dynamic policy for latent computation improves accuracy and generalization across reasoning tasks.
Method
Tyler learns a policy to choose between text token emission and specialized latent computation modules at each decoding step. Operators map the reasoning state into latent tokens for global planning, local updates, or procedural abstraction.
In practice
- Implement a policy-driven mechanism to invoke specialized latent computation modules.
- Utilize latent tokens for distinct reasoning functions like global planning or local state updates.
