The entry path to learning machine learning and logistic regression can be divided into the following steps:

1. Learn the basics of programming :

   • If you are not familiar with programming, first learn a programming language, and Python is recommended. Learn basic syntax, data types, process control, and master common programming tools and techniques.

2. Learn the basics of machine learning :

   • Learn the basic concepts, tasks, and methods of machine learning, and understand the basic principles of supervised learning and classification tasks. Learn common machine learning algorithms and models, including logistic regression, decision trees, support vector machines, etc.

3. Master the principles of logistic regression :

   • Learn the principles and methods of logistic regression models in depth. Understand the basic ideas, model structure and parameter estimation methods of logistic regression, as well as the application scenarios, advantages and disadvantages of logistic regression in classification tasks.

4. Learn data processing and analysis tools :

   • Learn to use data processing and analysis libraries in Python, such as NumPy, Pandas, and Matplotlib. Master how to load, process, and visualize data in preparation for training and evaluating a logistic regression model.

5. Practical projects :

   • Select some suitable data sets and tasks, such as binary classification problems or multi-classification problems, and practice the training and evaluation of logistic regression models. From data preparation, feature engineering to model training and evaluation, you can fully master the application process of logistic regression.

6. Parameter adjustment and optimization :

   • Learn how to adjust the hyperparameters of the logistic regression model to optimize model performance. Understand common parameter adjustment methods and techniques, such as grid search, cross-validation, etc., as well as how to handle unbalanced data and overfitting problems.
