FM-ChangeNet: Learning Change through Pathwise Feature Transport

arXiv:2607.04750v1 Announce Type: new Abstract: We present FM-ChangeNet, a pathwise-supervised framework for change detection that reformulates bi-temporal reasoning as continuous transport in feature space rather than static endpoint comparison. Given encoded pre and post-temporal representations, we construct intermediate latent states and learn a time-conditioned velocity field $\hat{v}_\theta(z_t,t)$ along the transformation trajectory. This pathwise formulation constrains the predictor over a continuum of intermediate states, providing a denser and less ambiguous supervision signal than c

Why this matters
Why now

The continuous drive for more robust and efficient AI models for tasks like change detection necessitates novel architectural approaches that can handle temporal data with greater fluidity.

Why it’s important

Improved change detection capabilities, particularly in computer vision and time-series analysis, have significant implications for autonomous systems, surveillance, environmental monitoring, and predictive maintenance.

What changes

This paper introduces a new method for detecting change by modeling continuous feature transport rather than discrete comparisons, potentially leading to more accurate and nuanced AI analyses of dynamic data.
