UniProbe: A Learnable Token-Level Hallucination Detector for Large VLMs using Multi-Structural Internal Representations
UniProbe detects hallucinated tokens in frozen LVLMs by jointly modeling attention graphs, image geometry, and response order, and uses this signal to resample bad tokens during generation.
