Machine Learning Algorithms - Regression Analysis and Decision Trees
We cover machine learning algorithms, especially regression analysis and decision trees, that are used to identify patterns in data and make predictions. You will understand what regression analysis and decision trees are and how they are used.
Data analysis is the process of predicting the future and explaining a given problem based on past data. The image below is a slide that appears at the beginning of the lecture ppt.
In addition to this lecture, we have covered 'technical analysis', which is the step of summarizing data characteristics and shapes, and 'exploratory analysis', which explores patterns, in the webinar replay series that is uploaded periodically and the [Data Understanding and Visualization Basics for Beginners] lecture, but there was no lecture on 'predictive/inferential analysis', so we are providing it this time :)
This lecture covers machine learning algorithms, one of the steps in making predictions and inferences. Many machine learning algorithms exist, but we'll examine regression analysis, the most basic yet crucial, and decision trees, which offer intuitive understanding.
This lecture is for these people!
I studied machine learning algorithms (regression analysis, decision trees), but I have a hard time understanding them. 🥺
I'm already analyzing and utilizing data well, but I want to reorganize the basic theory 🤔
It's hard to understand just through theory 😥
I'll solve it for you 👍
This course begins with an introduction to regression analysis and decision trees, and covers how to use them. It will lay a solid foundation for data manipulation.
You can understand more clearly through an example.
This lecture is 📢
A short and concise introduction to the basic concepts of regression analysis and decision trees in one lecture.
We also provide example datasets to help you understand the concepts more quickly and accurately.

Q&A 💬
Q. Is it okay if I don't have basic knowledge of statistics or coding?
Yes, that's fine. Since it primarily deals with theory, it helps you understand the theory. However, since the examples use R, having some knowledge of the subject will make it easier to understand!
Q. I heard there's a community where related videos are organized. How can I join?
The 'Data Hero' community provides a variety of data learning content, and many people are already communicating through Slack. If you're interested, check out the link below for a more detailed introduction to the community.😎
