Idea
A parameter-free decoding framework that reduces hallucinations in large language models for AI developers and enterprises.
Research Paper
Core Innovation
This paper presents HAVE, a novel decoding method that adaptively gates attention heads and calibrates value vectors to better reflect token contributions. Unlike prior approaches, it requires no finetuning and operates in a single forward pass, improving hallucination mitigation across multiple LLMs and benchmarks. It also integrates uncertainty scaling to fuse calibrated attention with language model distributions effectively.
Market Size (TAM)

Research Paper Overview
HAVE: Head-Adaptive Gating and ValuE Calibration for Hallucination Mitigation in Large Language Models
Summary
Large Language Models often hallucinate despite relevant evidence due to input-agnostic head importance and poor reflection of token contribution by raw attention weights; HAVE introduces a parameter-free decoding framework with head-adaptive gating for instance-level attention head reweighing and value calibration augmenting attention with value vector magnitudes to better align token-level evidence with model updates, fusing this with LM distribution via an uncertainty-scaled policy; it requires no finetuning, runs in a single forward pass, and consistently reduces hallucinations across multiple QA benchmarks and LLM families with modest overhead.
