Decision Making as a Data Scientist: Application of Game Theory

Introduction


Working as a data scientist involves making numerous decisions. Particularly, the experience of assigning the right job to the right person significantly influences the success of a project. In this essay, I will discuss my experience and propose solutions by applying the logic of microeconomics, specifically game theory.


Application of Game Theory


Game theory is a branch of economics that studies the behavior of interdependent decision-makers. By applying this theory, it is possible to predict what actions each member should take and what results can be obtained.


Specific Experience and Analysis


In my team, each member has a specific skill set. For example, some members are strong in machine learning, while others excel in data engineering. The success of the project heavily depends on optimally utilizing these skills.


This situation resembles the "cooperative game" in game theory. Each player (team member) chooses a strategy (which job to take) to maximize their benefit (success of the project). However, since the choices of other players also affect the outcome, it is crucial to find an optimal solution for the entire team.


Solution and Direction for Improvement


The solution to this problem is to apply the concept of "Nash equilibrium". Nash equilibrium refers to a state where all players are optimally responding to the strategies of other players without changing their strategies. By finding this state, we can decide which job each member should take.


Furthermore, through this analysis, a direction for improving future actions is suggested. Specifically, it is crucial to understand each member's skill set clearly and assign jobs considering it.


Conclusion


Decision making as a data scientist can be more efficient and effective by applying game theory. By using this theory, we can maximize team productivity through the experience of assigning the right job to the right person. In the future, we aim to make better decisions based on this analysis.

Welcome to the world of Bonsai!

Image
Bonsai is an art form that encapsulates the beauty and harmony of nature within a small pot. It serves as a mirror reflecting the human heart, revealing an infinite world within. Bonsai reflects the emotions, thoughts, and values of its caretaker. It symbolizes the relationship between humans and nature, showing how we coexist with, respect, and celebrate the beauty of nature. Bonsai is also a living art that experiences growth and change over time, serving as a metaphor for life itself. Each Bonsai weaves its own story through its journey of growth. It symbolizes the fragility and persistence of life, change and constancy, and above all, the passage of time. Therefore, Bonsai is more than just a plant; it is a philosophical expression that bridges the inner world of humans and the outer world. It is a mirror showing how we understand ourselves and the world, and how we interact with them. It is a world in itself. Welcome to the world of Bonsai! https://www.bing.com/ck/a?!&&p=8

Let’s learn how to prune bonsai

Image
"Bonsai Pruning" is the process of trimming the tree to control its growth. It involves cutting off parts of the branches to adjust the growth and fruiting of the tree, and to shape it. Pruning is an important task for maintaining the health and beauty of garden trees and shrubs. The basic steps of pruning are as follows Determine the purpose of pruning: If it's a garden tree for viewing, you prune to maintain a beautiful tree shape. On the other hand, if the purpose is cultivation, you cut off extra branches to promote the growth of the trunk and branches you want to grow. Determine the timing of pruning: Generally, evergreen trees are pruned around June when the vigorous spring budding has settled down and around October when the growth of summer branches has stopped. Conifers are pruned in spring and around October, and deciduous trees are pruned from November to March during their dormant period when the leaves have fallen. Decide which branches to prune: In order to

In bonsai terminology, "Ushiroeda" or "back branch"

In bonsai terminology, "Ushiroeda" or "back branch" refers to the branches that extend to the back of the trunk. These branches play a role in expressing the depth of the entire tree. The back branches are usually placed slightly spread out to the side so that the foliage can be seen from the front. The back branches that come out diagonally are finished in such a way that they peek out from between the branches, considering that the branches further away actually look smaller than the branches in front. The back branches play an important role in taking the balance of the entire tree and are arranged back and forth to bring out the three-dimensionality of the tree.
