Fi-NeMo: GPU-Accelerated Motif Calling from Neural Network Contribution Scores
anshulkundaje · x · 2026-09-09
Fi-NeMo, by Austin Wang, efficiently locates motif instances from model-derived contribution scores and maps them to TF-MoDISco motifs while modeling motif competition; a preprint is coming soon. It uses a proximal-gradient competitive optimization for sparse linear reconstruction, runs GPU-accelerated on PyTorch, and can catch low-prevalence cofactor motifs that sequence-based methods miss.
