Reliable anomaly detection (AD) in photovoltaic (PV) modules is 
critical for maintaining solar energy efficiency. However, the 
development of robust computer vision models for PV inspection is 
limited by the scarcity of large-scale, diverse, and balanced datasets.
In this study, we introduce a spatially conditioned denoising diffusion 
probabilistic model, PV-DDPM, designed to generate anomalous 
electroluminescence (EL) images across four PV cell types: 
multi-crystalline silicon (multi-c-Si), mono-crystalline silicon 
(mono-c-Si), half-cut multi-c-Si, and interdigitated back contact 
(IBC) with dogbone interconnect. 
PV-DDPM enables the controlled synthesis of both multi-defect and 
single-defect scenarios by conditioning on binary masks that 
represent structural features and defect positions.
To the best of our knowledge, this is the first framework that jointly 
models multiple PV cell types while allowing simultaneous 
generation of diverse anomaly types.
We also introduce E-SCDD dataset, an enhanced version of the 
SCDD dataset, comprising 1,000 pixel-wise annotated EL images 
spanning 30 semantic classes, and 1,768 unlabeled synthetic 
samples. Quantitative evaluation shows our generated images 
achieve a Fréchet Inception Distance (FID) of 4.10 and Kernel 
Inception Distance (KID) of 0.0023 ± 0.0007 across all categories. 
Furthermore, compared to training on the original SCDD dataset, 
training the vision–language anomaly detection model AA-CLIP 
on E-SCDD improves pixel-level AUC and average precision by 
1.70 and 8.34 points, respectively. Code and data are publicly 
released to ensure reproducibility.

This article introduces Attuned Design Practice (ADP), a design vocabulary and conceptual framework for producing embodied knowledge at the intersection of artistic and scientific inquiry, to inform the development of computational models that generate body-based interpretations and articulations. The convergence of Robotics, AI, HRI, and HCI in Industry 5.0 demand bold experimentation in artistic-scientific inquiry to interpret embodied knowledge beyond quantifiable data. In ADP, we propose the concept of ‘attunement’ to examine how alternative design vocabularies for embodied knowledge can be produced in reciprocity with the development of computational models that direct and facilitate expression and attunement over optimization or efficiency. Attunement is seen as a tuning fork to incrementally investigate the phenomena, relationships and patterns that inherently exist in tensions in-between tangible-intangible, or palpable-impalpable forms of materiality in human-computer connections, partnerships, and shared experiences. We propose Open Rehearsals, where-in alternative experiential understandings unfold in three areas of expertise: (1) preparing of tools and instruments, (2) performative practice, and (3) composition and choreography and notation methods. Our aim is to reinvent design innovation by cultivating integrative, reflective, and adaptive modes of collaborative design-making, from embodied discovery to embodied transformation.

Attuned Design Practice: towards Open Rehearsals for Embodied Knowledge and Computational Design.

This study investigates the intuitive relationship between manual gestures and vocal syllables, grounded in shared neurobiological and motor systems. Participants were tasked with producing "Synekinian pairs," consisting of vocal syllables paired with instinctive gestures. Through qualitative and quantitative analyses, the findings reveal consistent patterns in manual-vocal associations, offering insights into gesture-based sound design, vocal synthesis, gesture notation and human-computer interaction. Future work aims to refine the experimental methodology, expand datasets, and validate these observations across diverse cultural and linguistic contexts.

This study investigates how audiences perceive humor in both Human-created and AI-generated Manzai scripts, a traditional Japanese form of scripted stand-up comedy performed by a pair of comedians. We analyze laughter responses using two complementary modalities: explicit laughter, captured through real-time reaction-button inputs, and implicit laughter, measured via mouth-corner motion tracking. Comparative experiments are conducted to evaluate differences between Human-created and AI-generated Manzai scripts. The results reveal that while AI-generated Manzai scripts can elicit explicit laughter to a certain extent, it is less effective in inducing implicit laughter compared to Human-created script. Implicit laughter is observed only when explicit laughter occurred, suggesting that unconscious emotional reactions may precede conscious recognition of humor. Moreover, Human-created Manzai scripts that are contextually relatable and easy to imagine produced larger and more sustained mouth-corner movements, indicating that empathy and contextual understanding play key roles in embodied humor perception. These findings demonstrate that mouth-corner motion is a reliable indicator of subtle amusement and provide new insights into Bodily Expressed Emotion Understanding (BEEU) for AI-generated humor.

Predicting Valence-Arousal-Dominance (VAD) dimensions from bodily-expressed emotions in videos remains a fundamentally challenging task in affective computing, requiring models that capture subtle spatiotemporal patterns while balancing computational efficiency and interpretability. We present a comprehensive investigation of VAD prediction approaches on the newly introduced Annotated Bodily Expressed Emotion (ABEE) dataset, which contains approximately 3,200 video clips spanning 8 primary emotion categories and 20 subcategories. We explore two complementary methodologies: a feature-based gradient boosting approach using XGBoost with carefully engineered spatiotemporal features and dimensionality reduction, and deep learning architectures capable of learning hierarchical representations directly from raw video data. Our feature-based approach demonstrates exceptional computational efficiency, with sub-second training times and minimal resource requirements, while our deep models reveal the fundamental difficulty of capturing continuous VAD dimensions from bodily expressions. Through systematic evaluation on the ABEE dataset, we establish baseline performance for the VAD prediction task, achieving $R^2$ scores of -0.090, -0.014, and -0.058 for valence, arousal, and dominance, respectively, with our gradient boosting approach. These results highlight the substantial gap between current methodologies and the inherent complexity of bodily emotion signals, providing benchmarks for future research. We further discuss critical insights regarding feature engineering, temporal dynamics, and the intrinsic challenges of continuous emotion prediction from naturalistic video data, emphasizing the need for dedicated spatiotemporal modeling strategies tailored to bodily expressions.

Sketching is a widely used medium for generating and exploring early-stage design concepts. While generative AI (GenAI) chatbots are increasingly used for idea generation, designers often struggle to craft effective prompts and find it difficult to express evolving visual concepts through text alone. In the formative study (N=6), we examined how designers use GenAI during ideation, revealing that text-based prompting disrupts creative flow. To address these issues, we developed TalkSketch, an embedded multimodal AI sketching system that integrates freehand drawing with real-time speech input. TalkSketch aims to support a more fluid ideation process through capturing verbal descriptions during sketching and generating context-aware AI responses. Our work highlights the potential of GenAI tools to engage the design process itself rather than focusing on output.

The capacity for complex, evidence-grounded, and strategically adaptive persuasion remains a formidable grand challenge for artificial intelligence. Prior work, like IBM Project Debater, focused on generating isolated persuasive speeches in highly simplified and shortened debate formats for lay audiences. We introduce a novel autonomous system capable of participating in and winning a full, unmodified two-team competitive policy debate. Our system employs a hierarchi cal architecture of specialized multi-agent workflows, where teams of LLM-powered agents collaborate and critique one an- other to perform discrete argumentative tasks. Each workflow
utilizes iterative retrieval, synthesis, and self-correction using a massive corpus of policy debate evidence (OpenDebateEvidence) [Roush et al. 2024] and produces complete speech transcripts, cross-examinations, and rebuttals. We introduce a live, interactive end-to-end presentation pipeline that renders debates with AI speech and animation: transcripts are surface realized and synthesized to audio with OpenAI text-to-speech (gpt-4.1-tts), and then displayed as talking-head portrait
videos with EchoMimic V1 [Chen et al. 2024, 2025, OpenAI 2025e,c]. Beyond fully autonomous (AI vs. AI) matches, the system supports hybrid human–AI operation: human debaters can intervene at any stage, and humans can optionally serve as opponents against the AI in any speech, enabling AI–human as well as AI–AI rounds. In preliminary evaluations against human-authored cases, our system produces qualitatively superior argumentative components and consistently wins simulated rounds as adjudicated by an independent autonomous judge. Expert human debate coaches also prefer the arguments, evidence, and cases constructed by our system.

MOVE-ME is a wearable AI system that functions as a choreographic companion, designed to interrupt and inspire dancers’ improvisational flow in real time. Equipped with an on-body camera and speech synthesis, the system observes the dancer’s environment and responds to visual input and text prompts with spoken suggestions. These responses, ranging from poetic provocations to site-specific directives, create a feedback loop in which human and machine co-compose movement, challenging distinctions between spontaneity and computation, authorship and obedience.
The project explores AI as a relational agent rather than as a tool, an intelligent presence that shapes choreography through co-creation. MOVE-ME was featured in three practice-based research projects between 2024–2025, each testing different choreographic configurations and affective dynamics.

MOVE-ME: Dance Choreography with AI

This study presents a cross-cultural implementation of an artistic Brain–Computer Interface (BCI) and generative artificial intelligence (GenAI) system designed for live performance within the Balinese gamelan tradition. The BCI-GenAI system enables real-time translation of neural synchrony between dyads of performers (musician-musician, dancer-dancer, musician-dancer) into the control of culturally-relevant generative visual projections that interact with performers and audience alike.
Nine Balinese artists (six musicians and three dancers) participated in a two-part performance Janaki Dewi: Sita’s Reverie and Wiwada Manik: Tales of the Brothers. Dyads of artists wore Mobile Brain-Body Imaging (MoBI) technology to capture in real time their brain (electroencephalography, EEG) and ocular (electrooculography, EOG) activities, head motion, and video during rehearsals and a public performance over a period of 3 weeks. All signals were synchronized by hardware. A Brain-Computer Interface (BCI) preprocessed the MoBI Signals and computed the inter-brain synchrony between dyads. Synchrony indices derived from EEG bispectra modulated diffusion parameters in a StreamDiffusion-based GenAI, whereas text prompts consisting of culturally-relevant narrative and emotional descriptors reflected the story’s mythological and affective dimensions. Thus, the BCI-GenAI system linked the real-time inter-brain synchronization to dynamic imagery projected live on stage. The system thus functioned as a creative partner in-the-loop, responsive to both the emotional and rhythmic structure of performance. The multi-institutional, cross-cultural project contributes a methodological framework for BCI-GenAI in artistic settings, emphasizing cross-cultural collaboration, the symbiosis between cultural traditions and emergent technologies, and ethical data governance. It advances a model of responsible human–AI co-creation, where technology supports rather than displaces tradition thereby preserving the continuity of cultural identity through innovation, team science and transdisciplinarity.

An Artistic BCI-GenAI System Enabling Real-Time Co-Creation in Balinese Performance

This work-in-progress introduces SightDog, a hybrid framework that equips a robotic quadruped with multimodal artificial intelligence to support blind and visually impaired users. Designed as a robotic guide dog, SightDog integrates Vision–Language Models (VLMs) with schema-driven function calling to interpret natural language instructions and visual perception for navigation and assistance. A central focus is human–robot interaction: SightDog enables natural language dialog, provides contextual feedback, and adapts its responses to user intent in real time. In doing so, the system demonstrates a form of creative communication, where improvisation and adaptive dialog play a crucial role. In a simulation study, we show that SightDog can deliver environmental information and perform reactive navigation toward user-specified goals while managing obstacles and crosswalks. As part of this creative HRI, the system can also engage in informal dialog (e.g., telling casual jokes, which we illustrate in the experiment provided). While primarily an assistive prototype, the system also raises questions for interactive and creative AI, particularly regarding how AI systems respond to improvised human input. By situating SightDog within both accessibility and interactive AI research, this work contributes to discussions on human–robot collaboration and the future of guidance technologies.

SightDog: Function Calling and Creative Dialogue for AI‑Enhanced Guide Dogs

Despite remarkable advances in machine learning, real-time, online inference of agents’ intentions remains one of the enduring grand challenges in AI. Plan, activity, intent, and goal recognition involve making inferences about actors from observations of their behavior, whether they are software agents, robots, or humans. This tutorial targets AI students and researchers interested in exploring these recognition tasks to enhance their ongoing research or identify new research directions.
Attendees will leave with a clear understanding of core concepts, tasks, and relationships among plan, activity, intent, and goal recognition, as well as exposure to the state-of-the-art computational representations, algorithms, and empirical methodologies. The tutorial is innovative in its unification of fragmented research across multiple AI subfields and its use of live demonstrations to connect theory with practice. Building on the successful 2019 AAAI tutorial on the same topic (Keren, Mirsky, and Geib 2019), this session offers an updated and expanded perspective. It incorporates new material from the presenters’ co-authored book (Mirsky, Keren, and Geib 2021), along with the latest developments and advances in the field. Prerequisite knowledge: Familiarity with general AI concepts, probabilistic reasoning, and planning is recommended. Basic knowledge of Bayesian inference and logic-based reasoning will be helpful but not required.
