The method uses bounding-box evidence annotations to build target evidence representations and a soft contrastive branch-evidence alignment objective that pulls evidence-relevant branches toward annotated visual regions while contrasting them against negative evidence, instantiated on Qwen2.5-VL backbones and trained with standard supervised fine-tuning. On perception-intensive visual reasoning benchmarks, the method improved over the corresponding backbone and single-path latent reasoning baselines at both 3B and 7B scales.", "body_md": "arXiv:2610.36809v1 Announce Type: cross \nAbstract: Multimodal large language models have made substantial progress in visual question answering, but complex visual reasoning often requires locating and comparing multiple pieces of question-relevant visual evidence. Existing methods that move intermediate reasoning into the visual latent space usually follow a single linear reasoning trajectory, which can be limiting when multiple visual hypotheses or competing evidence regions are relevant. We propose Latent Visual Contrastive Reasoning, a branch-aware latent reasoning framework that generates multiple question-conditioned latent visual branches as soft hypotheses over image tokens. To train these branches, our method uses bounding-box evidence annotations to build target evidence representations and introduces a soft contrastive branch-evidence alignment objective. This objective encourages evidence-relevant branches to align with annotated visual regions while contrasting them against negative evidence. We instantiate our method on Qwen2.5-VL backbones and train it with standard supervised fine-tuning. Experiments on perception-intensive visual reasoning benchmarks show that the proposed method achieves overall improvements over the corresponding backbone and single-path latent reasoning baselines at both 3B and 7B scales.", "url": "https://wpnews.pro/news/latent-visual-contrastive-reasoning-with-multi-branch-exploration", "canonical_source": "https://www.machinebrief.com/news/latent-visual-contrastive-reasoning-with-multi-branch-explor-775w", "published_at": "2026-10-28 04:00:00+00:00", "updated_at": "2026-10-28 06:41:35.397507+00:00", "lang": "en", "topics": ["artificial-intelligence", "machine-learning", "computer-vision", "ai-research", "large-language-models"], "entities": ["arXiv", "Qwen2.5-VL", "Latent Visual Contrastive Reasoning"], "also_reported_by": [], "alternates": {"html": "https://wpnews.pro/news/latent-visual-contrastive-reasoning-with-multi-branch-exploration", "markdown": "https://wpnews.pro/news/latent-visual-contrastive-reasoning-with-multi-branch-exploration.md", "text": "https://wpnews.pro/news/latent-visual-contrastive-reasoning-with-multi-branch-exploration.txt", "jsonld": "https://wpnews.pro/news/latent-visual-contrastive-reasoning-with-multi-branch-exploration.jsonld"}}
