Serverless Machine Learning Classifier SlackBot
Medibot is a Slack bot running serverlessly in AWS via Chalice. Questions are passed to a machine learning classifier running in sci-kit learn. The SVM model is loaded on demand from S3 allowing it to be updated without redeploying or bloating the bot.
