いきなりThe Art of Modelingという章から入って、いいことたくさん書いてある。
有用なモデルの特性とは
- Ability characterize the observed data and to include the most important features of the data
- Makes accurate and precise predictions
- Increases understanding of the system
- The model is actually used
- The model is completed on time
- Logically consistent, plausible
- Validated by empirical observations
- Robust to small changes in the data
- Appropriate level of precision and detail
- As simple as possible
- Judged on what it is intended to do
- Has flexibility
- Is effective as a communication tool
- Serves many different purpose
- May allow for extrapolation outside the data range
LeadOptimizationのプロジェクトにおいては
- Ability characterize the observed data and to include the most important features of the data
- Is effective as a communication tool
の二つが特に重要なんだろうなぁと思う。自分でモデリングできるのであれば、前者だけを重要視するかもしれない。
