Large-Scale Hierarchical Topic Models

  title={Large-Scale Hierarchical Topic Models},
  author={Jay Pujara},
In the past decade, a number of advances in topic modeling have produced sophisticated models that are capable of generating hierarchies of topics. One challenge for these models is scalability: they are incapable of working at the massive scale of millions of documents and hundreds of thousands of terms. We address this challenge with a technique that learns a hierarchy of topics by iteratively applying topic models and processing subtrees of the hierarchy in parallel. This approach has a… CONTINUE READING
