We introduce a lightweight Mask R-CNN model that segments areas with the Ground Glass Opacity and Consolidation in chest CT scans. The model uses truncated ResNet18 and ResNet34 nets with …
A BERT-based Dual Embedding Model for Chinese Idiom Prediction
MinghuanTan, JingJiang....
Published date-11/04/2020
Chinese idioms are special fixed phrases usually derived from ancient stories, whose meanings are oftentimes highly idiomatic and non-compositional. The Chinese idiom prediction task is to select the correct idiom …
A deep learning classifier for local ancestry inference
MatthewAguirre, JanSokol, GuhanVenkataraman....
Published date-11/04/2020
SemanticSegmentation
Local ancestry inference (LAI) identifies the ancestry of each segment of an individual's genome and is an important step in medical and population genetic studies of diverse cohorts. Several techniques …
