Ideas
- Uncertain Environments
- Information about the environment has an unknown quality.
- Information about the environment has an unknown age.
- The environment can not be known in totality.
- Enough about the environment can not be known to make a decision with total confidence.
- Exploration/Exploitation Trade-Off Should an explored path be chosen or should a new path be chosen hoping for something better?
- This leads to risk assessment. What is the cost for each path? Given a good outcome? Given a bad outcome?
- Optimism Heuristic Treat uncertain outcomes as optimistically as the data allows: pick the alternative that, in the best possible world, is consistent with our experiences so far, and leads to the best outcome.
- Kaplan-Meier Estimator[1] Is a non-parametric statistic used to estimate the survival function from lifetime data.
