During Developer Conference 2019 in Mauritius, I explained "How Deep Learning Works" (Everyone is talking of Artificial Intelligence today as the next Big Thing! This session explains, from the point of view of a programmer, what a Neuron is, how a Neural Network can be built and how to use frameworks such as TensorFlow and TFLearn to quickly experiment with Deep Learning). Then I explained how to "Build a Chatbot using Deep Learning" (Smart devices of today, powered by e.g. Google Assistant, Apple Siri or Amazon Alexa, can chat with us in quite surprising ways. It is therefore interesting for a developer to understand how chatbots work. In this session, we will build a chatbot using Deep Learning techniques.)
