Properties of useful model

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。
