Loss Invariance Determines What Concept Layers Encode: Volume Grounding in Echocardiography
Hyunkyung Han, Min Jung Kim
The paper investigates how loss invariance affects the encoding of volume concepts in a transformer-based echocardiography model, showing that without explicit volume supervision t…

Ablation-Corrected Evaluation of Attribution Maps in Echocardiographic Ejection-Fraction Models
Hyunkyung Han, Min Jung Kim
The paper audits attribution methods for deep video models that estimate left‑ventricular ejection fraction from echocardiography, showing that while the models correctly focus on…
