You may already have some basic knowledge of mathematics and programming, which will help you understand and master deep learning more quickly. Here is a detailed entry path:

1. Mathematical foundation

Deep learning relies on some key mathematical concepts. I suggest you review the following:

• Linear Algebra : Matrix and vector operations, matrix decompositions (such as singular value decomposition).
• Calculus : Derivatives, integrals, multivariable calculus, especially partial derivatives and the chain rule.
• Probability and Statistics : basic probability theory, common distributions (such as normal distribution), expected value and variance, Bayes' theorem.
• Optimization theory : Understand the gradient descent algorithm and its variants (such as stochastic gradient descent, Adam optimizer).

2. Programming Basics

Python is the most commonly used programming language in deep learning, so you need to be familiar with Python and its related libraries:

• Python : Master basic syntax, data structures, functions, and classes.
• NumPy : For efficient numerical computing.
• Pandas : Data processing and analysis.
• Matplotlib/Seaborn : Data visualization.

3. Machine Learning Basics

Before delving into deep learning, first understand some basic concepts and algorithms of machine learning:

• Supervised learning : regression, classification (linear regression, logistic regression, support vector machine).
• Unsupervised learning : clustering (K-means, hierarchical clustering), dimensionality reduction (PCA).
• Evaluation methods : cross validation, confusion matrix, ROC curve.

4. Deep Learning Basics

Understand the basic structure and training methods of neural networks:

• Perceptrons and Multilayer Perceptrons (MLPs) : Learn about basic neuron models and forward propagation.
• Activation function : such as Sigmoid, Tanh, ReLU.
