Thank you
Thank you, that was really excellent, clear and informative to a numpty like me. I actually feel like I understood all that
A very humble person but most of all super smart… Thank you so much!!! Keep doing your great work.
"Let's open up our pizza shops in the west end"
"But nobody lives there?"
"Do it anyway. Trust me"
"OK"
…a year later, a 8.5 earthquake demolishes most of downtown San Francisco. Only the west end is spared. Massive number of people move to the west end.
It's called the "Gut Feeling Algorithm".
If in the email they use comment syntax such as this /* cheap */. Can the computer read it in order to mark it as spam?
Brilliant video! All concepts so nicely explained.

Thank you! It has put things I have learnt into easily graspable concepts.
mindblowing explanation. such lucid language! thanks a lot
Amazing explanation, wish you had been my college teacher, do you have an online course?
Awesome Vid
pleas can you tell me some referances about machine learning and sensing processing (free references)
Hi. Wonderful explanation. Can I pls get this presentation to gcsumit007@gmail.com!!
Please go through https://m.youtube.com/channel/UC7tzG9dDMcp0-WfGROT9cYw
Perfectly explained the mathematical approach of Machine learning
Perfect!

Absolutely brilliant 😀 Ur way of explaining concepts is able to build right intuition
First time I am much aware of the concept of machine learning and its algorithms, your examples are awesome. I am waiting for your more videos on machine learning. how we can start working on it?
I wouldn't want to repeat what others have been saying in the comments, but WOW, is this a great explanation of a complex topic. I just regret I only now discovered it. Will watch all your other videos. THANK YOU for putting the effort in this. <3
Hi Luis, I taught math classes for more than fifteen years and watched hundreds of videos on this topic. I can say that I am amazed by your videos and your teaching style. Examples, visualizations are great! You simplify the hard topics so well! Having a math phd tells the difference, too!
YOU ARE REALLY GOOD AT EXPLANING THINGS!!
insane ,tnx dude
I've study ML for several months and only this video has opened my mind. Thanks a million.

This is so far the first REALLY clear and well explained video related to Machine Learning. Thank you so much. your video is amazing and I'm happy to find it!
geat teacher and very helpful course
You really found your calling with teaching. These videos are phenomenal.
