Learning What's Real: Disentangling Signal and Measurement Artifacts in Multi-Sensor Data, with Applications to Astrophysics

Carolina Cuesta-Lazaro, Daniel Muthukrishna, David W. Hogg, Jeroen Audenaert, Marc Huertas-Company, Pablo Mercader-Perez, V. Ashley Villar, William T. Freeman

Overlapping observations from different instruments train a model to isolate intrinsic galaxy signals from sensor artifacts.

✓ Portable graph bundle live · download bundle · merged state

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

The resulting representations explicitly separate intrinsic signals from sensor-specific distortions and noise, and can be used for counterfactual view generation, parameter inference unconfounded by measurement distortions, and instrument-independent similarity search.

C2weakest assumption

That overlapping observations of the same physical objects across instruments provide sufficient signal to train a dual-encoder model to isolate sensor artifacts via counterfactual generation without additional labels or strong priors on the artifact distribution.

C3one line summary

A dual-encoder deep learning method disentangles intrinsic astrophysical signals from measurement artifacts by treating sensor effects as augmentations and using counterfactual generation on overlapping observations.
