The Hitchhiker's Guide to LDA
This is an incremental contribution aimed at helping beginners in academia and industry understand LDA more easily.
The paper tackles the challenge of learning the Latent Dirichlet Allocation (LDA) model by providing a detailed mathematical derivation and background knowledge to make it accessible for beginners, resulting in a book written in Chinese with the author's unique insights.
Latent Dirichlet Allocation (LDA) model is a famous model in the topic model field, it has been studied for years due to its extensive application value in industry and academia. However, the mathematical derivation of LDA model is challenging and difficult, which makes it difficult for the beginners to learn. To help the beginners in learning LDA, this book analyzes the mathematical derivation of LDA in detail, and it also introduces all the knowledge background to make it easy for beginners to understand. Thus, this book contains the author's unique insights. It should be noted that this book is written in Chinese.
