MotionBits: Video Segmentation through Motion-Level Analysis of Rigid Bodies

This paper introduces MotionBits, a novel concept and learning-free segmentation method that identifies the smallest manipulable rigid bodies through kinematic spatial twist equivalence, outperforming state-of-the-art embodied perception models on the new MoRiBo benchmark and enabling more effective downstream robotic manipulation and reasoning tasks.

Characterizing Faults in Agentic AI: A Taxonomy of Types, Symptoms, and Root Causes

This paper presents a comprehensive taxonomy of faults in agentic AI systems, derived from a large-scale empirical study of 13,602 issues and validated by 145 practitioners, which categorizes 37 distinct fault types, their symptoms, and root causes to reveal critical propagation patterns and mismatches between probabilistic LLM outputs and deterministic system constraints.

Active View Selection with Perturbed Gaussian Ensemble for Tomographic Reconstruction

This paper introduces Perturbed Gaussian Ensemble, an active view selection framework for sparse-view CT that leverages stochastic density scaling of uncertain Gaussian primitives to identify high-variance projections, thereby significantly improving reconstruction fidelity and reducing geometric artifacts compared to existing methods.

What Does AI Do for Cultural Interpretation? A Randomized Experiment on Close Reading Poems with Exposure to AI Interpretation

A randomized experiment involving 400 participants reveals that while AI assistance can enhance both performance and pleasure in close reading poems, the benefits are optimized with a single interpretation rather than multiple, as heavy reliance on AI improves task performance but diminishes the enjoyment of the experience.

Robodimm: A Physics-Grounded Framework for Automated Actuator Sizing in Scalable Modular Robots

The paper introduces Robodimm, a physics-grounded software framework that automates actuator sizing for scalable modular robots by leveraging Pinocchio and Pink to solve constrained inverse dynamics via a Karush-Kuhn-Tucker formulation, thereby addressing the complexities of coupled joint torques and self-weight effects in closed kinematic chains.

Not Too Short, Not Too Long: How LLM Response Length Shapes People's Critical Thinking in Error Detection

This study reveals that while the correctness of LLM-generated reasoning is the primary driver of user accuracy in critical thinking tasks, medium-length explanations uniquely enhance users' ability to detect errors when the AI's reasoning is incorrect, suggesting that response length plays a nuanced role in shaping human critical evaluation.
