This article explores the fundamental aspects of Latent Dirichlet Allocation (LDA), a highly-utilized unsupervised probabilistic technique for topic modeling. It elaborates the core principles of LDA, providing an accessible interpretation of the underlying mathematical concepts that dictate the operation of the model, as well as the training process using Gibbs Sampling with operable illustration. The real-world applications and potential extensions of the LDA model are also explored.
