At the highest level, for developers who don’t currently possess the technical skills required to implement AI models, or who lack the high-quality, “ground truth” data to train them, we provide AI services: Amazon Rekognition for image and facial analysis, Amazon Polly for text-to-speech, and Amazon Lex, an automatic speech recognition and natural language understanding service for building conversational chat bots. No deep learning expertise needed here: just visit the AWS console to get started. One level down, for customers with existing data who want to build custom models, we provide a set of AI platforms which remove the undifferentiated heavy lifting associated with deploying and managing AI training and model hosting: Amazon Machine Learning (with both batch and real-time prediction on custom linear models) and Amazon EMR (with Spark and Spark ML support).
