Today we’re joined by William Fehlman, director of data science at USAA. We caught up with William a while back to discuss:

  • His work on topic modeling, which USAA uses in various scenarios, including chat channels with members via mobile and desktop interfaces.
  • How their datasets are generated.
  • Explored methodologies of topic modeling, including latent semantic indexing, latent Dirichlet allocation, and non-negative matrix factorization.
  • We also explore how terms are represented via a document-term matrix, and how they are scored based on coherence.
