Sentiment Analysis: Building a Real-Time ML Application From Scratch

Throughout this workshop we are going to create together something cool: a python service that will read the audience messages sent to a chat, admit them into the chat if they are not abusive, reject them and send a warning SMS to the user if they are, and then perform sentiment analysis on the chat messages, all in real time!

So, you will use two ML models: one for sentiment analysis assessment and one for abusive language detection. We will see how to train these two and how to use state of the art model artifacts already trained. As crucial as getting the maths right, we will be building the MLOps that will cope with this real time use case. We will build a streaming infrastructure that reads from the chat topic, connects to the twilio API and uses big deep learning models all in real time.

For data scientists, data engineers or ML engineers, this is an amazing opportunity to learn about streaming, ML deployment, real time data processing, and some cool libraries that offer state of the art deep learning models. We encourage you to be excited but never scared if some of these areas sound way out of your skill set. We have experience teaching and two of us will be there to assist with any doubts/blockages. We will assume no previous knowledge and still will manage to get quite deep! All you need is python programming skills as this will be the language used, although certain data science experience would also be recommendable.

Join us for a fun and useful workshop!
