The rapid technical progress of generative art (GenArt) has democratized the creation of visually appealing imagery. However, achieving genuine artistic impact - the kind that resonates with viewers on a deeper, more meaningful level - remains formidable as it requires a sophisticated aesthetic sensibility. This sensibility involves a multifaceted cognitive process extending beyond mere visual appeal, which is often overlooked by current computational methods. This paper pioneers an approach to capture this complex process by investigating how the reasoning capabilities of Multimodal LLMs (MLLMs) can be effectively elicited to perform aesthetic judgment. Our analysis reveals a critical challenge: MLLMs exhibit a tendency towards hallucinations during aesthetic reasoning, characterized by subjective opinions and unsubstantiated artistic interpretations. We further demonstrate that these hallucinations can be suppressed by employing an evidence-based and objective reasoning process, as substantiated by our proposed baseline, ArtCoT. MLLMs prompted by this principle produce multifaceted, in-depth aesthetic reasoning that aligns significantly better with human judgment. These findings have direct applications in areas such as AI art tutoring and as reward models for image generation. Ultimately, we hope this work paves the way for AI systems that can truly understand, appreciate, and contribute to art that aligns with human aesthetic values.

Emotion alignment between music and palettes is crucial for effective multimedia content, yet misalignment creates confusion that weakens the intended message. However, existing methods often generate only a single dominant color, missing emotion variation. Others rely on indirect mappings through text or images, resulting in the loss of crucial emotion details. To address these challenges, we present Music2Palette, a novel method for emotion-aligned color palette generation via cross-modal representation learning. We first construct MuCED, a dataset of 2,634 expert-validated music-palette pairs aligned through Russell-based emotion vectors. To directly translate music into palettes, we propose a cross-modal representation learning framework with a music encoder and color decoder. We further propose a multi-objective optimization approach that jointly enhances emotion alignment, color diversity, and palette coherence. Extensive experiments demonstrate that our method outperforms current methods in interpreting music emotion and generating attractive and diverse color palettes. Our approach enables applications like music-driven image recoloring, video generating, and data visualization, bridging the gap between auditory and visual emotion experiences.
In the digital age, brand meaning is increasingly shaped through user participation and content sharing on social media platforms. However, significant perceptual gaps often exist between official brand narratives and consumer interpretations. These multimodal and cognitively nuanced gaps are challenging to detect and model using traditional analytical methods. To address this, we propose a multi-agent framework that metaphorically models perception as an optical process-propagation, interference, and measurement---termed OPIM. We construct a novel dual-perspective dataset from representative social media platforms, integrating text and image content from both user-generated and official brand communications. We evaluate brand perception along six psychological dimensions. Experiments across 15 brands demonstrate that our framework effectively captures key perception gaps, particularly in sincerity, professionalism, and attractiveness. In contrast, materialism and sophistication exhibit higher alignment between brand messaging and consumer perception. Our framework enhances the cognitive alignment and multimodal interpretability of large language models, offering actionable insights for brand strategy and bridging computational modeling with human-centric understanding. The dataset will be available at https://github.com/htgan-ai/OPIM.
Video anomaly detection (VAD) is vital for public safety, yet current approaches struggle with limited generalization, low interpretability, and high resource demands. To address these challenges, we propose HoloTrace, an edge-cloud collaborative VAD system that integrates large language models (LLMs) to construct and update a novel bidirectional causal knowledge graph. At the edge, HoloTrace leverages LLM-based cross-modal understanding and employs Hidden Markov Model (HMM) for bidirectional event reasoning, obtaining anomaly boundaries with low computational overhead. On the cloud side, LLMs are leveraged to dynamically update the Bi-CKG graph with key frames sent from the edge, in order to update causal relationships between events. Additionally, we introduce SVAD, a new large-scale VAD dataset comprising 632 real-world surveillance videos across 10 anomaly types and diverse scenes, with manually labeled frame-level annotations. Experimental results demonstrate that HoloTrace not only achieves the highest accuracy but also enhances interpretability and efficiency, paving the way for more generalizable and explainable video anomaly detection systems.
Personalized news recommendation aims to deliver content aligned with user interests. However, most existing methods rely on the objective textual content of news, overlooking the subjective social review that reflects how the news is socially perceived. Inspired by social constructionism, we propose Social Review-aware Recommendation (SRec), a novel framework that integrates both objective content and the social review. The latter is constructed through group deliberation modeled by an agent-based social simulator, providing structured representations of collective understandings toward news. In addition, SRec incorporates a reasoning-guided explanation module that produces interpretable rationales by aligning user preferences with the social review of news. Experimental results on the MIND-small and MIND-large datasets demonstrate that SRec improves AUC by at least 2.45% over competitive baselines. Further analysis confirms the value of the social review generated by the simulator, and shows the flexibility of SRec as a lightweight enhancement to existing recommendation systems.
The field of cross-modal retrieval aims to construct a shared representation space for samples from multiple modalities, typically within the vision and language domains. Deep hashing, with its high computational efficiency and low storage costs, has emerged as a central focus in this field and has garnered significant attention in recent research. However, current hash retrieval, concentrating on deterministic methods, struggles to effectively capture semantically ambiguous correspondences between cross-modal samples, where heterogeneous data have complex-semantic many-to-many relationships in the latent space. To address this limitation, we propose a novel Deep Probabilistic Binary Embedding (DPBE) framework, designed to generate discriminative, modality-invariant hash codes that facilitate accurate and reliable cross-modal retrieval. In contrast to contemporary probabilistic methods, we focus on optimizing hash networks to learn more accurate binary embeddings by using the learning mode of probabilistic embeddings. We introduce the first Bayesian encoder for hash learning, which employs Laplace Approximation to model a distribution over network weights. Extensive experimental results demonstrate that our approach not only outperforms deterministic methods in retrieval performance but also provides uncertainty estimates, enhancing the interpretability of the embeddings. The corresponding code is available at https://github.com/QinLab-WFU/DPBE.
We present VibeSpace, a novel method for the fully unsupervised construction of interpretable embedding spaces applicable to arbitrary domains. Our approach automates costly data acquisition by leveraging the knowledge embedded in large language models (LLMs), facilitating similarity assessments between entities for meaningful positioning within vector spaces, while also enabling intelligent mappings between vector space representations of disparate domains through a novel form of cross-domain similarity analysis. First, we demonstrate that our data collection methodology yields comprehensive and rich datasets across multiple domains, including songs, books, and movies. We validate the reliability of the automatically generated data via cross-checks with domain-specific catalogues. Second, we show that our method generates single-domain embedding spaces that are separable by domain-specific features, providing a robust foundation for classification tasks, recommendation systems, and other downstream applications. These spaces can be interactively queried for semantic information about different regions in embedding spaces. Lastly, by exploiting the unique capabilities of current state-of-the-art large language models, we produce cross-domain mappings that capture contextual relationships between heterogeneous entities that may not be attainable through traditional methods. This approach facilitates the creation of embedding spaces of any domain, which circumvents the need to collect and calibrate sensitive user data and provides deeper insights and better interpretations of multi-domain data.
Finance decision-making often relies on in-depth data analysis across various data sources, including financial tables, news articles, stock prices, etc. In this work, we introduce FINTMMBench, the first comprehensive benchmark for evaluating temporal-aware multi-modal Retrieval-Augmented Generation (RAG) systems in finance. Built from heterologous data of NASDAQ 100 companies, FINTMMBench offers three significant advantages. 1) Multi-modal Corpus: It encompasses a hybrid of financial tables, news articles, daily stock prices, and visual technical charts as the corpus. 2) Temporal-aware Questions: Each question requires the retrieval and interpretation of its relevant data over a specific time period, including daily, weekly, monthly, quarterly, and annual periods. 3) Diverse Financial Analysis Tasks: The questions involve 10 different financial analysis tasks designed by domain experts, including information extraction, trend analysis, sentiment analysis and event detection, etc. We further propose a novel TMMHybridRAG method, which first leverages a multi-modal LLM to convert data from other modalities (e.g., tabular, visual and time-series data) into textual format and then incorporates temporal information in each node when constructing graphs and dense indexes. Its effectiveness has been validated in extensive experiments, but notable gaps remain, highlighting the challenges presented by our FINTMMBench. The benchmark and source code will be made publicly available.
The rapid evolution of the online fashion industry has intensified the demand for interactive fashion retrieval systems capable of precise and flexible searches based on user-specified attribute modifications. However, prevailing fashion retrieval methods often overlook the distinctive distributional properties of fashion images and struggle to preserve semantic consistency during attribute manipulation. To address these limitations, we propose DiSCo, a novel disentangled attribute manipulation retrieval framework via semantic reconstruction and consistency regularization. Our approach comprises three key components: (1) An attribute-aware manipulation network that constructs target fashion embeddings through cross-modal attribute modification deltas, leveraging dedicated fashion attribute encoders; (2) A cross-modal semantic reconstruction network that synthesizes target images directly from modified attribute descriptions, supervised by adversarial and attribute classification losses to ensure interpretable edits; (3) An adaptive fusion mechanism that dynamically integrates attribute-modified embeddings with reconstructed image features. Extensive evaluations on two benchmark datasets (DeepFashion and Shopping100K) demonstrate that DiSCo achieves superior retrieval accuracy over state-of-the-arts while maintaining high-fidelity editing. Quantitative and qualitative analyses further confirm that DiSCo generates more realistic fashion representations, underscoring its effectiveness in attribute-aware retrieval tasks.
Same-product identification serves as a critical infrastructure in e-commerce systems, enabling accurate product matching across heterogeneous marketing representations for key applications such as price comparison and personalized recommendation. Conventional approaches typically depend on manual feature engineering and extensive rule tuning, which limits their adaptability to varying identification criteria across different product categories and inconsistent business scenarios. To overcome these challenges, we propose an end-to-end same-product identification model powered by multimodal large language models (MLLMs) that inherently support multimodal alignment and exhibit strong generalization across diverse real-world settings. We first introduce a novel group-wise annotation pipeline to construct a high-quality dataset, consisting of diverse product pairs with multimodal presentations and labeled at the SKU level. Building on this dataset, we incorporate task-specific training recipes from the perspective of data augmentation, resulting in our SaP-Bot, which demonstrates advanced performance and generalization capabilities. Moreover, we identify a strong correlation between the output logits of MLLMs and the product similarity, enabling interpretable confidence estimation that benefits both data annotation and downstream applications.
Crowd Dynamics Demand Adaptivity: Self-Adaptive Physics-Informed Neural Network for Crowd Simulation
Crowd simulation is crucial for urban planning, traffic management, public safety, and immersive environments. A fundamental challenge is capturing adaptive human behaviors that evolve dynamically with social interactions and task demands. Recently, physics-informed neural networks (PINNs) seamlessly integrate interpretable physics-based models with flexible data-driven learning, significantly enhancing simulation realism. However, current PINN-based methods typically rely on rigid representations of pedestrian perceptions and static task priorities of motion planning, limiting their ability to capture real-world social complexities and behavioral adaptability. To this end, we introduce SA-PINN, a novel Self-Adaptive Physics-Informed Neural Network specifically designed for modeling adaptive crowd behaviors. SA-PINN features two innovative adaptive modules: a self-adaptive social perception module, guided by a visual-field physics model to capture context-dependent social interactions dynamically; and a self-adaptive multi-task PINN training module, automatically balancing key motion objectives such as goal-reaching, collision avoidance, and alignment with real data. By jointly enabling perception-level and task-level adaptations within a unified physics-informed framework, SA-PINN generates highly realistic and physically consistent crowd simulations across diverse environmental contexts. Comprehensive evaluations on three real-world datasets (Lane, Cross 90, and GC) reveal that SA-PINN achieves a 29.7% gain in microscopic trajectory accuracy and enhances macroscopic density similarity by 23.5% compared to the best-performing baselines.
Public response prediction is critical for understanding how individuals or groups might react to specific events, policies, or social phenomena, making it highly valuable for crisis management, policy-making, and social media analysis. However, existing works face notable limitations. First, they lack micro-level personalization, producing generic responses that ignore individual user preferences. Moreover, they overlook macro-level sentiment distribution and only deal with individual-level sentiment, constraining them from analyzing broader societal trends and group sentiment dynamics. To address these challenges, we propose SocialAlign, a unified framework that predicts real-world responses at both micro and macro levels in social contexts. At the micro level, SocialAlign employs SocialLLM with an articulate Personalized Analyze-Compose LoRA (PAC-LoRA) structure, which deploys specialized expert modules for content analysis and response generation across diverse topics and user profiles, enabling the generation of personalized comments with corresponding sentiments. At the macro level, it models group sentiment distributions and aligns predictions with real-world sentiment trends derived from social media data. To evaluate SocialAlign in real-world scenarios, we introduce SentiWeibo, a large-scale dataset curated from authentic social interactions on the Weibo platform. Experimental results on our SentiWeibo and related LaMP benchmark demonstrate that SocialAlign surpasses strong baselines, showing improved accuracy, interpretability, and generalization in public response prediction. We hope our work inspires further research in public response prediction and computational social science: https://github.com/Znull-1220/SocialAlign.
MGHFT: Multi-Granularity Hierarchical Fusion Transformer for Cross-Modal Sticker Emotion Recognition
Although pre-trained visual models with text have demonstrated strong capabilities in visual feature extraction, sticker emotion understanding remains challenging due to its reliance on multi-view information, such as background knowledge and stylistic cues. To address this, we propose a novel multi-granularity hierarchical fusion transformer (MGHFT), with a multi-view sticker interpreter based on Multimodal Large Language Models. Specifically, inspired by the human ability to interpret sticker emotions from multiple views, we first use Multimodal Large Language Models to interpret stickers by providing rich textual context via multi-view descriptions. Then, we design a hierarchical fusion strategy to fuse the textual context into visual understanding, which builds upon a pyramid visual transformer to extract both global and local sticker features at multiple stages. Through contrastive learning and attention mechanisms, textual features are injected at different stages of the visual backbone, enhancing the fusion of global- and local-granularity visual semantics with textual guidance. Finally, we introduce a text-guided fusion attention mechanism to effectively integrate the overall multimodal features, enhancing semantic understanding. Extensive experiments on 2 public sticker emotion datasets demonstrate that MGHFT significantly outperforms existing sticker emotion recognition approaches, achieving higher accuracy and more fine-grained emotion recognition. Compared to the best pre-trained visual models, our MGHFT also obtains an obvious improvement, 5.4% on F1 and 4.0% on accuracy. The code is released at https://github.com/cccccj-03/MGHFT\_ACMMM2025.
There exists an affective gap between the video content and the emotions that the video creator hopes to evoke in viewers. Existing methods for video emotional content analysis attempt to learn emotion-related features directly or enhance the discrimination of models, but lack emotional cause descriptions, limiting their interpretability and the model's reasoning capabilities. In this work, we introduce EmoCause, the first large-scale video emotional dataset with multi-attribute, multi-split emotional cause descriptions. EmoCause builds upon existing datasets and is divided into 14K video splits, with over 294K emotional cause descriptions. Inspired by psychology and video prior knowledge, each video split is linked to four primary emotional cause attributes: audio, visuals, content, and shot, further divided into 12 sub-attributes, with each cause including a fact and analysis. Then, we merge all the causes into an emotional chain-of-thought for the entire video to enhance the reasoning process. Furthermore, we develop a multimodal large language model (MLLM) for video emotional content analysis, EmoDETective. EmoDETective performs training on EmoCause using progressive learning, which includes Detecting cause fact, Exploring cause analysis, and Thinking with complete reasoning. Experimental results show that our approach surpasses the existing MLLMs baseline and outperforms state-of-the-art methods, demonstrating superior emotional analysis capabilities. Ablation experiments indicate improvements from both the proposed dataset and training strategy. Code and datasets: https://github.com/Listever/EmoDETective/
Facial Emotion Analysis (FEA) plays a crucial role in visual affective computing, aiming to infer a person's emotional state based on facial data. Scientifically, facial expressions (FEs) result from the coordinated movement of facial muscles, which can be decomposed into specific action units (AUs) that provide detailed emotional insights. However, traditional methods often struggle with limited interpretability, constrained generalization and reasoning abilities. Recently, Multimodal Large Language Models (MLLMs) have shown exceptional performance in various visual tasks, while they still face significant challenges in FEA due to the lack of specialized datasets and their inability to capture the intricate relationships between FEs and AUs. To address these issues, we introduce a novel FEA Instruction Dataset that provides accurate and aligned FE and AU descriptions and establishes causal reasoning relationships between them, followed by constructing a new benchmark, FEABench. Moreover, we propose FEALLM, a novel MLLM architecture designed to capture more detailed facial information, enhancing its capability in FEA tasks. Our model demonstrates strong performance on FEABench and impressive generalization capability through zero-shot evaluation on various datasets, including RAF-DB, AffectNet, BP4D, and DISFA, showcasing its robustness and effectiveness in FEA tasks. The code will be available at https://github.com/953206211/FEALLM.
Stickers are increasingly used in social media to express sentiment and intent. Despite their significant impact on sentiment analysis and intent recognition, little research has been conducted in this area. To address this gap, we propose a new task: Multimodal chat Sentiment Analysis and Intent Recognition involving Stickers (MSAIRS). Additionally, we introduce a novel multimodal dataset containing Chinese chat records and stickers excerpted from several mainstream social media platforms. Our dataset includes paired data with the same text but different stickers, the same sticker but different contexts, and various stickers consisting of the same images with different texts, allowing us to better understand the impact of stickers on chat sentiment and intent. We also propose an effective multimodal joint model, MMSAIR, featuring differential vector construction and cascaded attention mechanisms for enhanced multimodal fusion. Our experiments demonstrate the necessity and effectiveness of jointly modeling sentiment and intent, as they mutually reinforce each other's recognition accuracy. MMSAIR significantly outperforms traditional models and advanced MLLMs, demonstrating the challenge and uniqueness of sticker interpretation in social media. Our dataset and code will be publicly available.
Depression poses significant challenges to patients and healthcare organizations, necessitating efficient assessment methods. Existing paradigms typically focus on a patient-doctor way that overlooks multi-role interactions, such as family involvement in the evaluation and caregiving process. Moreover, current automatic depression detection (ADD) methods usually model depression detection as a classification or regression task, lacking interpretability for the decision-making process. To address these issues, we developed InterMind, a doctor-patient-family interactive depression assessment system empowered by large language models (LLMs). Our system enables patients and families to contribute descriptions, generates assistive diagnostic reports for doctors, and provides actionable insights, improving diagnostic precision and efficiency. To enhance LLMs' performance in psychological counseling and diagnostic interpretability, we integrate retrieval-augmented generation (RAG) and chain-of-thoughts (CoT) techniques for data augmentation, which mitigates the hallucination issue of LLMs in specific scenarios after instruction fine-tuning. Quantitative experiments and professional assessments by clinicians validate the effectiveness of our system.
The application of Vision-Language Models (VLMs) in remote sensing (RS) image understanding has achieved notable progress, demonstrating the basic ability to recognize and describe geographical entities. However, existing RS-VLMs are mostly limited to image-level and region-level tasks, lacking the capability to handle pixel-level tasks and performing poorly in small-object recognition scenarios. Moreover, RS-VLMs consume significant computational resources when processing high-resolution RS images, further restricting their practical applicability. In this context, we propose GeoMag (Geographical Magnifier), an end-to-end general-purpose large model framework for RS. GeoMag dynamically focuses the attention scope based on prompt semantics to effectively perform remote sensing image parsing across multiple levels of granularity. This method introduces Task-driven Multi-granularity Resolution Adjustment and Prompt-guided Semantic-aware Cropping, which adaptively reduce the spatial resolution of task-irrelevant regions while enhancing the visual representation of task-relevant areas. This approach improves the model's perception of critical target regions, suppresses background redundancy, and reduces the computational cost of interpreting high-resolution RS imagery. Extensive comparative experiments on 10 benchmarks demonstrate that GeoMag not only excels in handling pixel-level tasks but also maintains competitive performance across tasks of other granularities compared to existing RS-VLMs.
Recent advances in Multimodal Large Language Models (MLLMs) have achieved remarkable progress in general domains and demonstrated promise in multimodal mathematical reasoning. However, applying MLLMs to geometry problem solving (GPS) remains challenging due to lack of accurate step-by-step solution data and severe hallucinations during reasoning. In this paper, we propose GeoGen, a pipeline that can automatically generates step-wise reasoning paths for geometry diagrams. By leveraging the precise symbolic reasoning, GeoGen produces large-scale, high-quality question-answer pairs. To further enhance the logical reasoning ability of MLLMs, we train GeoLogic, a Large Language Model (LLM) using synthetic data generated by GeoGen. Serving as a bridge between natural language and symbolic systems, GeoLogic enables symbolic tools to help verifying MLLM outputs, making the reasoning process more rigorous and alleviating hallucinations. Experimental results show that our approach consistently improves the performance of MLLMs, achieving remarkable results on benchmarks for geometric reasoning tasks. This improvement stems from our integration of the strengths of LLMs and symbolic systems, which enables a more reliable and interpretable approach for the GPS task. Codes are available at https://github.com/ycpNotFound/GeoGen.
Reasoning Like Experts: Leveraging Multimodal Large Language Models for Drawing-based Psychoanalysis
Multimodal Large Language Models (MLLMs) have demonstrated exceptional performance across various objective multimodal perception tasks, yet their application to subjective, emotionally nuanced domains, such as psychological analysis, remains largely unexplored. In this paper, we introduce PICK, a multi-step framework designed for Psychoanalytical Image Comprehension through hierarchical analysis and Knowledge injection with MLLMs, specifically focusing on the House-Tree-Person (HTP) Test, a psychological assessment test. First, we decompose drawings containing multiple instances into semantically meaningful sub-drawings, constructing a hierarchical representation that captures spatial structure and content across three levels: single-object level, multi-object level, and whole level. Next, we analyze these sub-drawings at each level with a targeted focus, extracting psychological or emotional insights from their visual cues. We also introduce an HTP knowledge base and design a feature extraction module, trained with reinforcement learning, to generate a psychological profile for single-object level analysis. This profile captures both holistic stylistic features and dynamic object-specific features (such as those of the house, tree, or person), correlating them with psychological states. Finally, we integrate these multi-faceted information to produce a well-informed assessment that aligns with expert-level reasoning. Our approach bridges the gap between MLLMs and specialized expert domains, offering a structured and interpretable framework for understanding human mental states through visual expression. Experimental results demonstrate that the proposed PICK significantly enhances the capability of MLLMs in psychological analysis. It is further validated as a general framework through extensions to emotion understanding tasks. Codes are released at https://github.com/YanbeiJiang/PICK.
