I lead machine learning and NLP efforts at Statt - working extensively with a large dataset of millions of public policy-related documents. Details include- Built/trained model to classify documents as relevant to public policy - goal was to weed out bad documents from our data collection- Built/trained model to classify documents with respect to type (white paper, commentary, press release, etc)- which greatly expanded search capabilities of the product- Employed over a dozen topic classification models to classify documents as discussing various public policy-related topics such as economics, housing, and transportation- Developed data collection and labeling strategies for these models for model training from our existing corpus of documents (which number in the millions)- Developed and deployed state-of-the-art entity linking solution in PyTorch which greatly expanded the data collected from each of our documents- Developed text summarization service built on existing model that was fine tuned with relevant training data.
