You Only Train Once: Differentiable Subset Selection for Omics Data

arXiv:2512.17678v2 Announce Type: replace Abstract: Selecting compact and informative gene subsets from single-cell transcriptomic data is essential for biomarker discovery, improving interpretability, and cost-effective profiling. However, most existing feature selection approaches either operate as multi-stage pipelines or rely on post hoc feature attribution, making selection and prediction weakly coupled. In this work, we present YOTO (you only train once), an end-to-end framework that jointly identifies discrete gene subsets and performs prediction within a single differentiable architect

Why this matters
Why now

The proliferation of complex biological datasets, particularly single-cell transcriptomics, necessitates more efficient and interpretable methods for biomarker discovery and data analysis, making joint optimization critical.

Why it’s important

This work directly addresses a key bottleneck in omics data analysis, enabling more accurate, interpretable, and cost-effective selection of relevant biological features, accelerating drug discovery and personalized medicine.

What changes

Traditional multi-stage or post hoc feature selection in omics is replaced by an end-to-end differentiable framework, YOTO, leading to better-coupled selection and prediction outcomes.
