Building scalable systems to understand content

What this post added

This post details the development and scaling of FBLearner Flow, a platform for machine learning pipelines, and Lumos, a computer vision platform built on top of it. It highlights the use of deep learning for image and video understanding, enabling features like automatic alt text (AAT) with action recognition and descriptive photo search based on object recognition and image embeddings. The post also discusses the technical aspects of training models using labeled data, semantic clustering, and the use of quantization techniques for image embeddings.
