All of us know random forests, one of the most popular ML models. They are a supervised learning algorithm, used in a wide variety of applications for classification and regression.
Can we use random forests in an unsupervised setting? (where we have no labeled data?)
Isolation forests are a variation of random forests that can be used in an unsupervised setting for anomaly detection.
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!
Prolly the clearest explanation I've watched. Much appreciated!
True , it is explained very nicely
Best short explanation I've found on TH-cam. Very straight to the point (pun intended) with clear explanation.
anomaly detected
Extremely clear, thank you!
Got my subscription and bell - thank you so much for the in-depth yet totally understandable explanation!
Thank you for making this video and it's very succint and straight to the point
Thank you, this was fantastic!
This was great. Thank you very much
Ma'am it was very well explained with all the mathematical details.
Thank you! Very nice explanation:)
Wow, this video was incredibly informative!
Thank you🤗
Thanks. Very clear.
Thank you very much
amazing, thank you from NYC
This is a great tutorial
Great work
Short and crisp.
Well explained..
Very understandable
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
mam what type of feature we are selecting here
What's an isolation tree then ?
great explanation. Thanks
