This document discusses an approach for optimizing follow-up observations of astronomical transients using Bayesian decision theory. The approach uses transient lightcurve models, telescope noise models, and prior information to calculate the information content of potential future observations. Observations are prioritized based on their expected information content to efficiently classify transients. The presenter outlines the necessary components for a software system to implement this approach, including lightcurve generation, data fitting, calculating confusion matrices, and an observation scheduler. Future work involves integrating these components and testing the system in realistic simulations.

Summary
Information content is just a penalty
function for scoring predicted
observations.
Using it to decide when to observe is
applied Bayesian decision theory.
But doing this for real requires a
number of non-trivial software
components.
Nearly ready for testing!
