Cognifest NYC 2017: Samantha Hansen, From prototyping to deploying, building ML systems with Featran

ai.bythebay.io Nov 2025, Oakland, full-stack AI conference Scale By the Bay 2019 is held on November 13-15 in sunny Oakland, California, on the shores of Lake Merritt: https://scale.bythebay.io. Join us! ----- "From prototyping to deploying, building ML systems and how Featran can help" The talk focuses on how to use Featran for both model training and within a service that evaluates the model. A challenge when requesting predictions from a model is ensuring that the input features used during training are identical to the on the fly features constructed within the service. This requires coordination between the offline training and the online servicing of predictions. To highlight this issue we detail a Spotify use case of building a classification model that predicts the probability of a playlist being streamed. We outline how and where Featran was used when going from conception to model deployment.
