What is data mining?

As a type of data analysis, Exploring and analyzing data to find meaningful patterns or rulesIt refers to.

Amidst a lot of data

In order to extract insights

What should I do?

1 ️ DATA PROCESSING:

I process it according to the shape I want to analyze.

The 'analysis method' is also important for data analysis, but what kind of data is collected and processed into what form determines the major direction of analysis. Therefore, you will learn how to combine multiple data frames to extract the desired value, and handle duplicate data and missing values.

2 ️ QUALITY DATA Statistics:

Obtain the desired value by processing statistics.

We will approach the data mathematically using more advanced statistical techniques, such as how to draw a regression line and find outliers, starting with a simple average.

3 ️ DATA Visualization:

Draw various charts to extract insights.

When data exists only in table form, it is difficult to extract deep insights from it. We will look at visualization methods that suit the purpose of the data, such as box plots, broken lines, bars, and platters, and draw the most appropriate chart using various visualization libraries.

It doesn't end with drawing a chart, but looks at how to read and interpret a chart from the perspective of an insightful informant.

4 ️ Text mining:

Analyze text data.

Insights can be extracted not only from numerical data, but also from text. We will look at a word cloud method that can extract key words from a large amount of text and visualize them.

I will be with you in all of these processes

#1 Programming Lesson Instructor,

This is Kwak Kyung-il from a non-major.

Hallo I'm a non-major, but currently Kwak Kyung Il is taking the first place in programming lessons at the extracurricular platform Hiding. I was able to take the first place in the lesson because I know best what is difficult and what points I don't understand from the standpoint of a non-major.

Not only tutoring, but also universities such as Yonsei University, Ewha Womans University, Sungkyunkwan University, and Chonnam National University Large companies such as Samsung Heavy IndustriesHe also gave lectures directly in, and was featured on Sin Saimdang and Jeong Yung Yong's channels, and met many people.

▶ Student reviews

The reason I had no choice but to become the number one programming instructor.

Until now, I have met many non-majors and taught them the basics of Python, data mining, and artificial intelligence. Class 101 presents the first online course on data mining with a curriculum that has been completely verified by receiving several times of immediate feedback.

From 1) the basics of data, 2) processing and processing data according to the desired purpose, 3) generating statistical values, 4) extracting insights through visualization, to 5) methods of dealing with text data. I'll teach you the whole process of data mining.
