Abstract

DNA molecules commonly exhibit wide interactions between the nucleobases. Modeling the interactions is important for obtaining accurate sequence-based inference. Although many deep learning methods have recently been developed for modeling DNA sequences, they still suffer from two major issues: 1) most existing methods can handle only short DNA fragments and fail to capture long-range information; 2) current methods always require massive supervised labels, which are hard to obtain in practice. We propose a new method to address both issues. Our neural network employs circular dilated convolutions as building blocks in the backbone. As a result, our network can take long DNA sequences as input without any condensation. We also incorporate the neural network into a self-supervised learning framework to capture inherent information in DNA without expensive supervised labeling. We have tested our model in two DNA inference tasks, the human variant effect and the open chromatin region of plants, where the experimental results show that our method outperforms five other deep learning models. Our code is available at https://github.com/wiedersehne/cdilDNA.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
