One of the key challenges is how to train powerful models while being prudent stewards of our clients' essential business data, and how to do so while respecting the increasingly complex landscape of international data regulation. // Bio Katrina Ni Katrina is a Machine Learning Engineer in Slack ML Services Team where they build ML platforms and integrate ML, e.g. Recommend API, Spam Detection, across product functionalities. Prior to Slack, she is a Software Engineer in Tableau Explain Data Team where they build tools that utilize statistical models and propose possible explanations to help users inspect, uncover, and dig deeper into the viz. Aaron Maurer Aaron is a senior engineering manager in the infra organization at Slack, managing both the machine learning team and the real-time services team. In six years at Slack, most of which Aaron spent as an engineer, He worked on the search ranking, recommendation, spam detection, performance anomaly detection, and many other ML applications. Aaron is also an advisor to Eppo, an experimentation platform.
