However, their deployment in safety-critical\ndomains poses significant challenges. Existing safety fine-tuning methods,\nwhich focus on textual or multimodal content, fall short in addressing\nchallenging cases or disrupt the balance between helpfulness and harmlessness.\nOur evaluation highlights a safety reasoning gap: these methods lack safety\nvisual reasoning ability, leading to such bottlenecks. To address this\nlimitation and enhance both visual perception and reasoning in safety-critical\ncontexts, we propose a novel dataset that integrates multi-image inputs with\nsafety Chain-of-Thought (CoT) labels as fine-grained reasoning logic to improve\nmodel performance. Specifically, we introduce the Multi-Image Safety (MIS)\ndataset, an instruction-following dataset tailored for multi-image safety\nscenarios, consisting of training and test splits. Our experiments demonstrate\nthat fine-tuning InternVL2.5-8B with MIS significantly outperforms both\npowerful open-source models and API-based models in challenging multi-image\ntasks requiring safety-related visual reasoning. This approach not only\ndelivers exceptional safety performance but also preserves general capabilities\nwithout any trade-offs. Specifically, fine-tuning with MIS increases average\naccuracy by 0.83% across five general benchmarks and reduces the Attack Success\nRate (ASR) on multiple safety benchmarks by a large margin.

This limitation is evident in tasks that require precise\nvisual perception, like comparing geometric properties or solving visual\nreasoning problems. To study this failure mode, we focus on vector graphics --\nimages composed of 2D objects and shapes, prevalent in LMM-based tasks in web,\ndesign, and OS environments. We identify two key research questions: how can we\nenable precise visual perception, and how can we facilitate high-level\nreasoning based on such low-level perceptions? To capture fine visual details,\nwe use Scalable Vector Graphics (SVG) for accurate encoding of visual scenes.\nHowever, SVGs are not readily interpretable by LMMs in a zero-shot manner. To\ntackle this, we propose the Visually Descriptive Language Model (VDLM), which\nintroduces a Primal Visual Description (PVD) as an intermediate textual\nrepresentation. PVD translates SVGs into a text-based abstraction consisting of\nprimitive attributes (e.g., shape, position, measurement) and their\ncorresponding values. PVD can be learned using task-agnostic synthesized data\nand represents visual primitives that are universal across vector graphics.\nThis abstraction is more structured, allowing for direct interpretation by\nfoundation models for zero-shot generalization.

The results demonstrated\nthat both multi-agent models. Multi-Agent 1, which includes the Initializer,\nCritic, and Scorer agents, and Multi-Agent 2, which comprises only the\nInitializer and Critic agents; significantly improved solution quality for TSP\nand mTSP problems. Multi-Agent 1 excelled in environments requiring detailed\nroute refinement and evaluation, providing a robust framework for sophisticated\noptimizations. In contrast, Multi-Agent 2, focusing on iterative refinements by\nthe Initializer and Critic, proved effective for rapid decision-making\nscenarios.

First, we introduce an\nevaluation protocol that includes Visual Commonsense Reasoning (VCR), Visual\nEntailment (SNLI-VE), and Visual Question Answering (VQA), across a variety of\ndata availability constraints and conditions of domain shift. Second, we\npropose an approach, named CLIP Targeted Distillation (CLIP-TD), to\nintelligently distill knowledge from CLIP into existing architectures using a\ndynamically weighted objective applied to adaptively selected tokens per\ninstance. Experiments demonstrate that our proposed CLIP-TD leads to\nexceptional gains in the low-shot (up to 51.9%) and domain-shifted (up to\n71.3%) conditions of VCR, while simultaneously improving performance under\nstandard fully-supervised conditions (up to 2%), achieving state-of-art\nperformance on VCR compared to other single models that are pretrained with\nimage-text data only. On SNLI-VE, CLIP-TD produces significant gains in\nlow-shot conditions (up to 6.6%) as well as fully supervised (up to 3%). On\nVQA, CLIP-TD provides improvement in low-shot (up to 9%), and in\nfully-supervised (up to 1.3%). Finally, CLIP-TD outperforms concurrent works\nutilizing CLIP for finetuning, as well as baseline naive distillation\napproaches.

Existing visual reasoning\napproaches typically utilize supervised methods to extract 2D segmentation\nmasks on which concepts are grounded. In contrast, humans are capable of\ngrounding concepts on the underlying 3D representation of images. However,\ntraditionally inferred 3D representations (e.g., point clouds, voxelgrids, and\nmeshes) cannot capture continuous 3D features flexibly, thus making it\nchallenging to ground concepts to 3D regions based on the language description\nof the object being referred to. To address both issues, we propose to leverage\nthe continuous, differentiable nature of neural fields to segment and learn\nconcepts. Specifically, each 3D coordinate in a scene is represented as a\nhigh-dimensional descriptor. Concept grounding can then be performed by\ncomputing the similarity between the descriptor vector of a 3D coordinate and\nthe vector embedding of a language concept, which enables segmentations and\nconcept learning to be jointly learned on neural fields in a differentiable\nfashion. As a result, both 3D semantic and instance segmentations can emerge\ndirectly from question answering supervision using a set of defined neural\noperators on top of neural fields (e.g., filtering and counting).

The motivation comes from the fact that\nmost existing visual reasoning tasks, such as CLEVR in VQA, are solely defined\nto test how well the machine understands the concepts and relations within\nstatic settings, like one image. We argue that this kind of \\textbf{state\ndriven visual reasoning} approach has limitations in reflecting whether the\nmachine has the ability to infer the dynamics between different states, which\nhas been shown as important as state-level reasoning for human cognition in\nPiaget's theory. To tackle this problem, we propose a novel\n\\textbf{transformation driven visual reasoning} task. Given both the initial\nand final states, the target is to infer the corresponding single-step or\nmulti-step transformation, represented as a triplet (object, attribute, value)\nor a sequence of triplets, respectively. Following this definition, a new\ndataset namely TRANCE is constructed on the basis of CLEVR, including three\nlevels of settings, i.e.~Basic (single-step transformation), Event (multi-step\ntransformation), and View (multi-step transformation with variant views).\nExperimental results show that the state-of-the-art visual reasoning models\nperform well on Basic, but are still far from human-level intelligence on Event\nand View.

Particularly, we explore two critical\nresearch problems existed in VQA: (1) efficiently fusing the visual and textual\nmodalities; (2) enabling the visual reasoning ability of VQA models in\nanswering complex questions. To address these challenging problems, a novel\nQuestion Guided Modular Routing Networks (QGMRN) has been proposed in this\npaper. Particularly, The QGMRN is composed of visual, textual and routing\nnetwork. The visual and textual network serve as the backbones for the generic\nfeature extractors of visual and textual modalities. QGMRN can fuse the visual\nand textual modalities at multiple semantic levels. Typically, the visual\nreasoning is facilitated by the routing network in a discrete and stochastic\nway by using Gumbel-Softmax trick for module selection. When the input reaches\na certain modular layer, routing network newly proposed in this paper,\ndynamically selects a portion of modules from that layer to process the input\ndepending on the question features generated by the textual network. It can\nalso learn to reason by routing between the generic modules without additional\nsupervision information or expert knowledge. Benefiting from the dynamic\nrouting mechanism, QGMRN can outperform the previous classical VQA methods by a\nlarge margin and achieve the competitive results against the state-of-the-art\nmethods. Furthermore, attention mechanism is integrated into our QGMRN model\nand thus can further boost the model performance. Empirically, extensive\nexperiments on the CLEVR and CLEVR-Humans datasets validate the effectiveness\nof our proposed model, and the state-of-the-art performance has been achieved.", "comment": null, "links": []}

In this paper, we\ninvestigate using weak annotation instead of strong annotation to train a video\ncaptioning model. To this end, we propose a progressive visual reasoning method\nthat progressively generates fine sentences from weak annotations by inferring\nmore semantic concepts and their dependency relationships for video captioning.\nTo model concept relationships, we use dependency trees that are spanned by\nexploiting external knowledge from large sentence corpora. Through traversing\nthe dependency trees, the sentences are generated to train the captioning\nmodel. Accordingly, we develop an iterative refinement algorithm that refines\nsentences via spanning dependency trees and fine-tunes the captioning model\nusing the refined sentences in an alternative training manner.

In particular, we present two interesting and\nimportant findings using IEP-Ref: (1) the module trained to transform feature\nmaps into segmentation masks can be attached to any intermediate module to\nreveal the entire reasoning process step-by-step; (2) even if all training data\nhas at least one object referred, IEP-Ref can correctly predict no-foreground\nwhen presented with false-premise referring expressions.

We report uneven performance of\nvarious deep CNN models on these two tasks.

We are motivated by a hypothesis from cognitive\nneuroscience which posits that the human visual cortex is modularized, and this\nallows the visual cortex to learn higher order invariances. To this end, we\nconsider a modularized variant of the ResNet model, referred to as a Residual\nMixture Network (ResMixNet) which employs a mixture-of-experts architecture to\ninterleave distributed representations with more specialized, modular\nrepresentations. We show that very shallow ResMixNets are capable of learning\neach of the two tasks well, attaining less than 2% and 1% test error on the\nMNIST Parity and the colorized Pentomino tasks respectively.

Recognizing object categories,\nparticular instances of objects and viewpoints/poses of objects are three\ncritical subproblems robots must solve in order to accurately grasp/manipulate\nobjects and reason about their environments. Multi-view images of the same\nobject lie on intrinsic low-dimensional manifolds in descriptor spaces (e.g.\nvisual/depth descriptor spaces). These object manifolds share the same topology\ndespite being geometrically different. Each object manifold can be represented\nas a deformed version of a unified manifold. The object manifolds can thus be\nparameterized by its homeomorphic mapping/reconstruction from the unified\nmanifold. In this work, we develop a novel framework to jointly solve the three\nchallenging recognition sub-problems, by explicitly modeling the deformations\nof object manifolds and factorizing it in a view-invariant space for\nrecognition. We perform extensive experiments on several challenging datasets\nand achieve state-of-the-art results.", "comment": null, "links": []}
