Deep Learning for Characterizing Sequence Reads

Published:

In this research project, we show that using a deep learning based DNA language model we can achieve performance in sequence classification approaching the performance of standard mapping algorithms. The performance of our model was most comparable to the performance of mapping when the input sequences were mutated at a higher rate (0.1 snps per bp).

[Preprint] A Recovery Algorithm and Pooling Designs for One-Stage Noisy Group Testing Under the Probabilistic Framework

Published in medRxiv, 2021

The main contributions of this paper include a practical one-stage group testing protocol guided by maximizing pool entropy and a maximum-likelihood recovery algorithm under the probabilistic framework.

[Preprint] OpenFold: Retraining AlphaFold2 yields new insights into its learning mechanisms and capacity for generalization

Published in bioRxiv, 2022

Here we report OpenFold, a fast, memory-efficient, and trainable implementation of AlphaFold2, and OpenProteinSet, the largest public database of protein multiple sequence alignments. We use OpenProteinSet to train OpenFold from scratch, fully matching the accuracy of AlphaFold2. Having established parity, we assess OpenFold's capacity to generalize across fold space by retraining it using carefully designed datasets.
