What Were You Thinking? Filling in Missing Dataflow Through Inference in Learning from Demonstration
This paper addresses the problem of learning from demonstrations involving unobservable (e.g., mental) actions. We explore the use of knowledge base inference to complete missing dataflow and investigate the approach…

Subject-Matched Templates for Spatial Normalization
Here, we introduce the concept of subject-matched templates. Rather than using a single template for the entire population, a different template is used for every subject, with the template matched…
