Abstract
A method and a system for counteracting model drift in a Latent Dirichlet Allocation (LDA) model by maintaining freshness and accuracy in the LDA model by leveraging LDA classification and vector algebra to detect potential degradations are provided. The method entails determining whether an LDA model has drifted and therefore requires retraining based on measurements of cosine similarities of respective topics that correspond to two LDA models and a topic match entropy between the two LDA models that is determined based on the measurements.
