• Developed KPI’s for a key model that reflect downstream impact which included developing a model to reduce the amount of data to be labeled and coordinating with a third party company for labeling.
• Audited internal training data to understand the scale and impact of poor training samples on our model, which led to an effort to monitor new and existing training data.
• Implemented content similarity method using Word2Vec embeddings in SQL to improve robustness of internal topic similarity process and reduce onboarding time for new employees.
