Who is this presentation for?

  • Data scientists, machine learning engineers, product managers, and developers




When built well, AI assistants provide great strategic business value and are fun to interact with. However, the majority of assistants built to this day are developed using just a set of rules and don’t go beyond simple FAQ interactions. This doesn’t scale in production and provides a rather disappointing user experience.

Tyler Dunn challenges the usual approach of chatbot development by introducing machine learning-based methods for dialogue management. You’ll learn the fundamentals of conversational AI, machine learning techniques behind natural language and dialogue management, and the basics of using Rasa Stack—an open source ML-based framework that empowers developers to build contextual assistants in-house.

Prerequisite knowledge

  • A basic understanding of machine learning applications

What you'll learn

  • Learn machine learning models behind the NLU and dialogue management, techniques for training NLU models without pretrained word vectors, and best practices for gathering and preparing the training data and closing the feedback loop using real-time user feedback
  • Understand how to implement conversational assistants from scratch using open source tools Rasa NLU and Rasa Core
