Please can anybody explain what is the difference between E(h(x)) and c(m) because E(h(x)) is also the average values of h(x) over all iTrees and c(m) is also the average value of h(x)? Please i am really confused what is the difference between them!!
E(h(x)) is the average values of h(x) over all iTrees but only for data point "x" c(m) is the same but it is calculated only from the "m" samples from the training dataset
Most probably the best explanation on internet related to Isolation Forest/Anomaly detection
Excellent Video with a short, clear explanation of the iForest algorithm! thank you for sharing!
Best short explanation I've found on UA-cam. Very straight to the point (pun intended) with clear explanation.
anomaly detected
Prolly the clearest explanation I've watched. Much appreciated!
True , it is explained very nicely
Got my subscription and bell - thank you so much for the in-depth yet totally understandable explanation!
Thank you🤗
Ma'am it was very well explained with all the mathematical details.
Extremely clear, thank you!
Wow, this video was incredibly informative!
Thank you very much
Well explained..
amazing, thank you from NYC
great explanation. Thanks
Thank you for making this video and it's very succint and straight to the point
Short and crisp.
Thank you, this was fantastic!

What's an isolation tree then ?
This is a great tutorial
mam what type of feature we are selecting here
This was great. Thank you very much
Thank you! Very nice explanation:)
Thanks. Very clear.
Great work
