We are working on a probabilistic model that particularly addresses issues concerning endogenous change---situations in which the system changes state but not as a result of exogenous forces applied to the system. In our domain---medical prediction, diagnosis, and treatment decisions---an exogenous event would be a planned treatment or test, and an endogenous event would be something like internal bleeding causing vital signs to destabilize. We are working on models that can be easily assessed from a human expert.
Another goal of the project is to understand the difference between the way Statisticians and Computer Scientists have approached the problem of temporal reasoning, and to say something interesting about causality in the process.
