今日有感而发，整整5年太不容易了。
What is "machine learning," and what are things like "logistic regression," "decision trees," "random forests," "support vector machines," etc.?

How are these things related to artificial intelligence? To understand these concepts, I spent nearly 5 years, approximately over 1800 days, delving into the foundational mathematical theories.

Especially at the crucial moment towards the end of 2023, I started learning "R language," and suddenly everything became clear.

Finally, after a whole five years, every day spent pondering what they are and how to use them, the arduous journey of deep learning came to an end. It was a challenging period of self-improvement, with no one to share, no one to support, and no one to understand. However, on January 11, 2024, today, I completed this path and finally embarked on a new journey: implementing an AI stock trading model.
