TL;DR: It is found that deep learning has yet to revolutionize biomedicine or definitively resolve any of the most pressing challenges in the field, but promising advances have been made on the prior state of the art.
Journal ArticleDOI

Žiga Avsec,Žiga Avsec,Melanie Weilert,Avanti Shrikumar,Sabrina Krueger,Amr Alexandari,Khyati Dalal,Khyati Dalal,Robin Fropf,Charles McAnany,Julien Gagneur,Anshul Kundaje,Julia Zeitlinger,Julia Zeitlinger +13 more
TL;DR: BPNet as discussed by the authors uses DNA sequence to predict base-resolution chromatin immunoprecipitation (ChIP)-nexus binding profiles of pluripotency transcription factor (TF) binding motifs.

TL;DR: A deep learning model is introduced that uses DNA sequence to predict base-resolution ChIP-nexus binding profiles of pluripotency TFs, and interpretation tools are developed to learn predictive motif representations and identify soft syntax rules for cooperative TF binding interactions.

Deep learning at base-resolution reveals motif syntax of the cis-regulatory code

TL;DR: A deep learning model is trained that uses DNA sequence to predict base-resolution binding profiles of four pluripotency transcription factors Oct4, Sox2, Nanog, and Klf4 and finds that instances of strict motif spacing are largely due to retrotransposons, but that soft motif syntax influences motif interactions at protein and nucleosome range.

Separable Fully Connected Layers Improve Deep Learning Models For Genomics
TL;DR: A new separable fully connected layer is presented that learns a weights tensor that is the outer product of positional weights and cross-channel weights, thereby allowing the same positional patterns to be applied across multiple convolutional channels.
