Topological shadowing for linear operators
Y. Yang, C. A. Morales
We prove a linear operator of a finite-dimensional Banach space has the topological shadowing property, as introduced in \cite{lny}, if and only if its spectrum lies either within…
Class Geometry as Supervision for Sample-Efficient Open-World Detection
Akash Rao, Zhou Chen, Revanth Reddy Palem +3
Open-world object detection requires models to recognize known categories, reject unfamiliar objects, and incorporate new classes over time. This is especially challenging in scarc…
CVT-Bench: Probing Spatial-State Integrity through Counterfactual Viewpoint Transformations
Shanmukha Vellamcheti, Uday Kiran Kothapalli, Disharee Bhowmick +1
Multimodal large language models (MLLMs) perform strongly on isolated spatial tasks, but whether their predictions remain persistent and mutually coherent across viewpoints and com…
CRAFT-E: A Neuro-Symbolic Framework for Embodied Affordance Grounding
Zhou Chen, Joe Lin, Carson Bulgin +1
Assistive robots operating in unstructured environments must understand not only what objects are, but what they can be used for. This requires grounding language-based action quer…
Generalized Event Partonomy Inference with Structured Hierarchical Predictive Learning
Zhou Chen, Joe Lin, Sathyanarayanan N. Aakur\\
Humans naturally perceive continuous experience as a hierarchy of temporally nested events, fine-grained actions embedded within coarser routines. Replicating this structure in com…
STaTS: Structure-Aware Temporal Sequence Summarization via Statistical Window Merging
Disharee Bhowmick, Ranjith Ramanathan, Sathyanarayanan N. Aakur
Time series data often contain latent temporal structure, transitions between locally stationary regimes, repeated motifs, and bursts of variability, that are rarely leveraged in s…
