Build chatbots of the future. Create sophisticated conversational agents using NLP and TensorFlow About This VideoBuild smart and interactive chatbots using NLP and TensorFlow and use them for business or personal useTrain and build smart chatbots that simulate written speech with authentic conversationsIntegrate chatbots to your business applications to provide solutions 24/7 without enduring long wait periods involving human agents, thus ensuring customer satisfactionIn DetailHave you ever waited for a long time to get a solution from a customer care executive? Also, wouldn't it be nice to have a personal assistant handy to help you with queries and give suggestions? Chatbots provides solutions to these issues.This course will show you how to create chatbots based on two models. You will design a user-friendly chatbot which responds using perfect grammar and informative answers from a predefined database. You will also learn how to build chatbots that form the answers themselves without having to look into a database. You will also understand the capabilities, and overcome the limitations, of each chatbot. This helps to reduce the need for human effort and costs. Using a chatbot will help scale your business and improve customer relations.By the end of the course, you'll be able to build smart chatbots that are always ready to provide solutions.All the code files for this course are available on Github at - https://github.com/PacktPublishing/Interactive-Chatbots-with-TensorFlow-Downloading the example code for this course: You can download the example code files for all Packt video courses you have purchased from your account at http://www.PacktPub.com.
