Hybrid Smoothed Dirichlet-Family Regression Framework for Fake News Detection
Standard multinomial models inadequately capture the sparsity, burstiness, and dependence present in highdimensional bag-of-words text. In this paper, we develop regression-based generative formulations of Smoothed Dirichlet (SD), Smoothed Generalized Dirichlet (SGD), and Smoothed Generalized Dirichlet Multinomial (SGD...
