A previously identified communication behavior, online commentary, is physician talk that describes what he/she is seeing, feeling, or hearing during the physical examination of the patient. The investigators who identified this communication behavior hypothesized that its use may be associated with successful physician resistance to perceived or actual patient expectations for inappropriate an...

Modern practitioners use machine learning to guide their decisions in applications ranging from marketing and targeting to policy making and clinical trials. To embrace automated decision-making in closed loops, it is crucial to make decisions safely and efficiently, as poor decisions waste human resources and result in social and economic costs. To this end, I propose to build a comprehensive ...

In an online decision problem, one makes a sequence of decisions without knowledge of the future. Tools from learning such as Weighted Majority and its many variants 13, 18, 4] demonstrate that online algorithms can perform nearly as well as the best single decision chosen in hindsight, even when there are exponentially many possible decisions. However, the naive application of these algorithms...

We initiate the study of online pricing problems in markets with “buyback,” i.e., markets in which prior allocation decisions can be revoked, but at a cost. In our model, a seller receives requests online and chooses which requests to accept, subject to constraints on the subsets of requests which may be accepted simultaneously. A request, once accepted, can be canceled at a cost which is a fix...
