Evidencepartial
We propose \textbf{CtrlCoT}, a dual-granularity CoT compression framework that harmonizes semantic abstraction and token-level pruning through three components
Implicationpartial
The abstract explicitly introduces CtrlCoT and describes its core mechanism.
Verificationpartial
partial
Evidencepartial
On MATH-500 with Qwen2.5-7B-Instruct, CtrlCoT uses 30.7% fewer tokens
Implicationpartial
This is a specific quantitative result presented in the abstract.
Verificationpartial

Evidencepartial
while achieving 7.6 percentage points higher than the strongest baseline
Implicationpartial
This is a specific quantitative result presented in the abstract, comparing against a baseline.
Verificationpartial
partial
Evidencepartial
Moreover, combining the two is non-trivial due to sequential dependency, task-agnostic pruning, and distribution mismatch.
Implicationpartial
The abstract highlights the difficulties of existing methods in combining different compression strategies.
Verificationpartial
partial
Evidencepartial
Hierarchical Reasoning Abstraction produces CoTs at multiple semantic granularities
Implicationpartial
The abstract details the components of CtrlCoT, and this claim describes the function of one component.
Verificationpartial
partial
Evidencepartial
Logic-Preserving Distillation trains a logic-aware pruner to retain indispensable reasoning cues (e.g., numbers and operators) across pruning ratios
Implicationpartial
The abstract details the components of CtrlCoT, and this claim describes the function of another component.
Verificationpartial
partial
Evidencepartial
Distribution-Alignment Generation aligns compressed traces with fluent inference-time reasoning styles to avoid fragmentation.
Implicationpartial
The abstract details the components of CtrlCoT, and this claim describes the function of the third component.
Verificationpartial
partial
Evidencepartial
The approach may not generalize to all LLM applications, and there is potential risk of losing critical information in reasoning for tasks outside the tested domains.
Implicationpartial
This is explicitly stated as a caveat in the provided analysis.
