Abstract:
At Yelp, we train and deploy models for a variety of business applications requiring low-latency model inference. At first we focused on streamlining support for XGboost and LR models built in Spark to support business recommendations, search, ads, restaurants, and trust & safety use-cases. However, we didn’t have a way of supporting low-latency neural network models with Tensorflow. Such models usually relied on batched model inference in support of models used for photo classification [1] and popular dishes [2].

In this talk, we give an architectural overview of our ML Platform and how we overhauled it to support neural network models in low-latency ranking applications. We cover how we built in the capabilities to train and deploy Tensorflow-based models using MLEAP and cataloged them in MLFlow. We also discuss the deployment plugin that was using Elasticsearch and how this transitioned to using Yelp’s own near-real time search (Nrtsearch) [3] open-source framework. Lastly, we cover the issues faced along the way in terms of latency and model performance, including how we incorporate embedded features in the model.
