为了解决跷跷板和负迁移的现象,论文提出了一种共享结构设计的渐进式分层提取(ple)模型。 其包含两部分, 一部分是一种显式区分共享专家塔和特定任务专家塔的门控 ( CGC ) 模型,另一部分是由单层CGC结构扩展到多层的PLE模型。
Progressive Layered Extraction (PLE): A Novel Multi-Task …
2020年9月22日 · To address these issues, we propose a Progressive Layered Extraction (PLE) model with a novel sharing structure design. PLE separates shared components and task-specific components explicitly and adopts a progressive routing mechanism to extract and separate deeper semantic knowledge gradually, improving efficiency of joint representation ...
Protein-losing enteropathy in Fontan circulation: Pathophysiology ...
2022年3月7日 · Protein-losing enteropathy (PLE) represents a rare but severe and potentially life-threatening complication following Fontan operation in patients with a functional single ventricle. PLE is characterized by enteric protein loss, leading to devastating multiorgan involvement with increased morbidity and mortality.
Diagnosis and Management of Protein-losing Enteropathies
Protein-losing enteropathy (PLE) is a syndrome caused by a variety of gastrointestinal diseases causing the enteric loss of albumin and globulin. 1,2 Intestinal inflammation, infiltration, ulceration, blood loss, and primary or secondary lymphangiectasia are well …
