ConCA: Concentration-Aware Channel Attention for Fine-Grained Visual Recognition

ConCA is proposed, which pairs the mean with a shift-invariant negative-input entropy (NegEnt), computed via a softmax over the negated activations, forming a dual descriptor that jointly encodes magnitude and concentration.

Physics-Constrained Generative Inference of Sub-Crystal Electromagnetic Shower Structure in a Segmented Calorimeter

The finite transverse granularity of a segmented electromagnetic calorimeter fundamentally limits the precision with which the observables of a shower can be reconstructed, among them its position, its lateral profile, and the direction of the incident particle. We show that a substantial fraction of the information su...
