Diagnostic accuracy of salivary gland ultrasonography with different scoring systems in Sjögren’s syndrome: a systematic review and meta-analysis
Noninvasive objective salivary gland ultrasonography (SGU) had been widely used to evaluate major salivary gland involvement in primary Sjögren’s syndrome (pSS) and treatment responses. However, the… Expand

Interpretable and Personalized Apprenticeship Scheduling: Learning Interpretable Scheduling Policies from Heterogeneous User Demonstrations
TLDR
We propose a personalized and interpretable apprenticeship scheduling algorithm that infers an interpretable representation of all human task demonstrators by extracting decision-making criteria via an inferred, personalized embedding non-parametric in the number of demonstrator types. Expand
