Robust machine learning algorithms for text analysis

Ke, Shikun; Olea, José Luis Montiel; Nesbit, James - In: Quantitative economics : QE ; journal of the … 15 (2024) 4, pp. 939-970

We study the Latent Dirichlet Allocation model, a popular Bayesian algorithm for text analysis. We show that the model's parameters are not identified, which suggests that the choice of prior matters. We characterize the range of values that the posterior mean of a given functional of the...
