Fix exam wrong answer in DA0101EN
Question 20 asks what you should do if a model gives R^2 = 1 on train set and R^2 = 0 on validation data. There are 3 options, I tried to answer with 2 submissions and the obviously wrong answer (model works fine on test data so it has no issues) is the only remaining option.
Please fix this as some people could feasibly need this one question to pass the course.

Hadoop 101 course
The course has good content, but the instructor is just reading the lines instead of trying to explain them meaningfully. It definitely needs improvement. Please look into it.
Thanks.

Focus on Conepts
1) Please add a session on Terms/Glossary/Blockchainspeak.
2) Focus on how Security is stronger in Blockchain as opposed to traditional processes.
3) Explain the terms Provenance, Immutability and Finality with better examples and define what they mean exactly.1 vote -
Download Slides
I see that video and transcript download is available, but I think it would also be useful to provide slides as it is easier to reference material from slides while working on labs.

Relability of Website
I encourage lot of people to go for this site and learn, trusting upon the reliability. I found them complaining regularly about the lack of reliability of the website, mostly slow or down, as from past 2 days not able to login to https://courses.cognitiveclass.ai/login. It affects the trust and user engagement. On top of that even after a day of not working,we have not found a single notification saying what is happening. Please build a monitoring system and assign a responsible person to make sure the website functions professionally, even in down time.
