Do AI Activity Indices Really Measure AI Activity?
Riccardo Bertamini, Hugo M. V. Arsenio, Lorenzo Caputi +1
AI dashboards increasingly shape economic debate, yet their headline movements often conceal what changed. For a ratio, the same rise can reflect numerator growth, denominator decl…
Modeling The Object Representations Underlying Human Physical Reasoning
Andrey Gizdov, Andrea Procopio, Yichen Li +4
Humans appear to represent objects when reasoning about physics with coarse, volumetric "bodies" that smooth concavities, trading fine visual detail for efficient physical predicti…
Time-Series at the Edge: Tiny Separable CNNs for Wearable Gait Detection and Optimal Sensor Placement
Andrea Procopio, Marco Esposito, Sara Raggiunto +3
We study on-device time-series analysis for gait detection in Parkinson's disease (PD) from short windows of triaxial acceleration, targeting resource-constrained wearables and edg…
Towards aligned body representations in vision models
Andrey Gizdov, Andrea Procopio, Yichen Li +2
Human physical reasoning relies on internal "body" representations - coarse, volumetric approximations that capture an object's extent and support intuitive predictions about motio…
