Rasa NLU, Rasa Core - How to build a Facebook Massenger Chatbot
Do you want to create a talking chatbot that interacts with your visitors? In this tutorial, you will learn how to create Python chatbots using Rasa NLU and Rasa Core. They provide several Natural Language processing functions that parse user input and match it to the right response. Integrating NLP into your bot can be difficult, but with Rasa, it is much easier to create a Facebook Messenger bot or a website chatbot.
Rasa is a powerful open-source machine learning framework for developers to create contextual chatbots and expand bots beyond answering simple questions. In this course, you will study both Rasa NLUÂ and Rasa Core.
Rasa NLU is an open-source natural language processing tool for intent classification and entity extraction in chatbots. You can think of it as a set of high-level APIs for building your own language parser using existing NLP and ML libraries. Among the main reasons for using open-source NLU are: 1) you don’t have to hand over all your chatbot training data to Google, Microsoft, Amazon, or Facebook; 2) Machine Learning is not one-size-fits-all. You can tweak and customize Python chatbot models for your training data; and 3) Rasa NLU runs wherever you want, so you don’t have to make an extra network request for every chatbot message that comes in.
Rasa Core leverages developers’ existing domain knowledge to help them bootstrap from zero training data, and adopts an interactive learning approach. With Rasa Core, you manually specify all the things your bot can say and do. We call these actions. One action might be to greet the user, another might be to call an API, or query a database. Then you train a probabilistic model to predict which action your Python chatbot should take given the history of a chatbot conversation.

AIÂ Enthusiast and a Software Developer with over 6+ years of development experience using multiple open source technologies. Presently, I'm freelancing Computer Vision and Chatbot Development projects. I started my Freelance career back in 2011, have been doing multiple projects of multiple types. Since, I have a Bachelors Degree in Marine Engineering, I used to do Freelance CAD/CAM projects initially....
There is good hands-on material.I would like to see fully connected end to end project approach i.e from data collection , data reprocessing , data cleaning,model training and evaluation, model selection and then deployment. Still a good learning experience .
Please Udemy community delete this course from your site. This is the worst course I have ever seen.
I have just completed DialogFlow part of the course. Before getting started with the course, I am at an intermediate level in using Dialogflow. The instructor isn't explaining the errors(why and what the error is or how to fix it). He's just going with the flow by correcting errors. We expect to know what the error is and alternatives.
Context is such a confusing and important thing in chatbots and it wasn't clearly explained. I think Dialogflow videos should be updated with new videos with a precise explanation.
In the Rasa section, the video is blur for most of the time. Please check and update.
Thank you
good and great
The video is blur !!
Content is outdated
Course was really great. Enjoyed a lot developing chatbots following the course.
The course is what I expected. Only the procedure has been explained but the reasons for doing them are not as yet.
is there any approach defined before he starts the course?pathetic....
