While Latent Dirichlet Allocation (LDA) and probabilistic approaches dominate the field of Natural Language Processing (NLP), a robust class of methodologies utilizes mathematical programming (optimization) to solve the topic modeling problem. This paper reviews the formulation of topic modeling as a matrix factorization problem, specifically focusing on Non-negative Matrix Factorization (NMF), Sparse Coding, and constrained optimization models. These methods offer advantages in computational efficiency, convergence speed, and the ability to impose specific structural constraints (e.g., sparsity) on the resulting topics.

Modelling in mathematical programming involves representing a real-world problem as a mathematical model, which consists of a set of variables, constraints, and an objective function. The goal of the model is to optimize the objective function, subject to the constraints, which represent the limitations and requirements of the problem. The model is typically formulated using mathematical notation, such as linear or nonlinear equations, inequalities, and logical statements.
