演讲摘要:De novo genome assembly is one of the most important tasks in computational biology and bioinformatics. However, de novo genome assembly is challenging due to (i) sequencing errors, (ii) sequencing bias and (iii) repetitive regions. In this talk, our recent work on de novo genome assembly around these three challenges will be introduced first. Then, an ensemble machine learning model LoopPredictor will be introduced to predict the genome topology for any cell type which lacks a 3D profile. LoopPredictor is able to efficiently identify cell type-specific enhancer mediated loops, and promoter-promoter interactions, with a modest feature input requirement. LoopPredictor enables the dissection of cell type-specific long-range gene regulation, and can accelerate the identification of distal disease-associated risk variants
