・ Hold out (divide the training data at a certain ratio and divide it into training data and test data.) However, if the data arrangement is not uniform, good learning results will not be obtained. In that case, shufflesplit is used to shuffle the elements according to the division. -Cross validation is one of the analysis methods performed using shuffle split. How to divide the data used for learning each time, select a different block, and repeat when the number of data at hand is not enough
-Perform "regression" processing to predict the correlation. ・ When I proceeded according to the book, I found a place where an error occurred. The function was undefined because the module was not imported. Although it was described properly in the final summary, it was not described in the middle of the process, so if you proceed without thinking, it will probably get stuck. Even if you just notice it, you can feel a little growth.
With the above contents, the above book has been read.
Although I have read the above book, I am working on it because I want to solidify the basics at this very first stage. It is a program that creates one thing step by step while receiving a guide, and it is very studying because you can output in a different aspect from studying by using books. There are 5 Python learning courses in total, and I finished up to 4 in a day today. In addition to Python, there were courses on Java, Ruby, and Git, so I found it very useful for beginners.
