My favorite two songs, Let it be and Let it go, has opposite meanings. - promotes the idea that you can make a decision to let something go and because of that decision, it will be gone. I am a person with strong style. I’ve Gotta Be Me-style mantra for West Wing devotees to the power of playing to your strengths. This is where it started; a memo reveals public dissatisfaction with Bartlet’s perceived ineffectiveness, and his staff’s subsequent decision to let him off the leash. The resulting flurry of liberal policies is the reason why everyone still wishes that Bartlet was the real president. Legends of the fall and Let it go: what to seek and hear from our model I am biased toward Bayes and System Dynamics. First, they presented an implementable tool for my life vision "affordable cutting-edge analytics for all". Second, intellectual sexiness of figure and Geppetto of them. This discipline combines the theory, methods, and philosophy needed to analyze the behavior of systems — not only in management, but also in such other fields as environmental change, politics, economic behavior, medicine, and engineering. A concentration in System Dynamics draws on organization studies, behavioral decision theory, and engineering to provide a common foundation for understanding and influencing how things change over time. Students study principles of systems, economic and industrial dynamics, and policy analysis, while doing additional work in economics, information systems, statistics, and political science. Batman completes Joker. Every rise end up falling. Local-global, agent-compartment, parameter-hyperparameter are relative adjectives which triggers the questions: "what decision cannot be myopic"? As Research should 1. Reverse Copernican heliocentrism in Galilei (1632) "Dialogue Concerning the Two Chief World Systems" Copernican heliocentrism rebelled against human's self-centeredness, but simulation need this spirit. The root of this difference can be found in reductionism vs constructionism or science vs simulation. We build model to cater our own needs (`decision`) on the world we perceive (`draw`). Based on this demand, we search for the supply of real world's `data`. As a homage to "Dialogue Concerning the Two Chief World Systems", our goal can be named as "Dialogue Bridging Two Constructed Systems along Decision, Draws, Data". The two systems are 🔺 SF and 🟢 CP model. 2. Specify Kahneman (2011) "Thinking fast and slow" We interpret fast and slow as 🔺 SF's short term forecast and 🟢 CP's long term forecast, both of which collaborate to optimize policy. When thinking fast, we act with experience-based intuition which is same as how🔺 SF propagates uncertainty with pre-estimated parameter with historical data. Disadvantage of 🔺, e.g. inability to extrapolate, is complemented by 🟢 's causal structure that has both explainability and outlasting effect via embedded mechanism. Matter-based initialization is needed, as opposed to form assuming independence and continuous which was proven to be different (e.g. non existence of Brownian motion defined as independent increments with stationary outcome) a.k.a. CustomSafety, precision from the user. The degree of conservativeness should be given to the stakeholders. Robust opitimization only allows one extreme: preventing the worst case. However, this can be avoided with binning.
