Description

We've talked about, speculated and often seen different applications for Artificial Intelligence - But what about one piece of technology that will not only gather relevant information, better customer service and could even differentiate your business from the crowd?

ChatBots are here, and they came change and shape-shift how we've been conducting online business. Fortunately technology has advanced enough to make this a valuable tool something accessible that almost anybody can learn how to implement.

If you want to learn one of the most attractive, customizable and cutting edge pieces of technology available, then this course is just for you!

Who this course is for:
  • Any students in college who want to start a career in Data Science
  • Any Data Science enthusiast
  • Anyone interested in creating their own ChatBot
  • Anyone interested in Artificial Intelligence, Machine Learning or Deep Learning and its applications

These guys are awesome... I only have 1 thing to add, hope my comment will be seen by them.. I wish there was more correlation between intuition and the practical example, for example, when you explain the gradient descent method in intuition, it would be great during the coding section when you choose optimizer = 'adam' , just give a very quick flashback to intuition. I'm not saying you don't do, but I am asking to kindly do it more... love you guys, ali
