Early Cue Precision Shapes Visual Shortcut Learning in Controlled Cue-Manipulation Benchmarks
Chanho Park, Woochan Lee, Janyeong Oh +4
Visual classifiers can achieve high matched-distribution accuracy while relying on low-level cues that fail under conflict or suppression. We test whether this failure is shaped by…

Covariant Chu-Kovasznay Decomposition: Resolving Thermodynamic Ambiguity in Compressible Flows
Chanho Park, Gyeongho Gong, Yeachan Kwak +1
We establish the Covariant Chu--Kovasznay Decomposition (CCKD), a geometric framework that resolves thermodynamic ambiguity in compressible mode content by formulating the decompos…

Covariant Helmholtz-Hodge Decomposition: Resolving Spurious Vorticity via Acoustic Geometry
Chanho Park, Yeachan Kwak, Seongim Choi
The separation of acoustic and vortical fluctuations in compressible turbulence becomes ambiguous in thermodynamically inhomogeneous media, where refraction by entropy gradients an…
