Was just going through my Uni data mining slides and couldn't make sense of it. Thanks so much, your intuition to solving this problem was demonstrated so clearly
Why are you taking frequent 2 item sets for generating rules? aren't we supposed to take only last frequent item set i.e 3 item set and make rules out of it only?
@@goodstudy7948bcz initially, we are given that there are sometimes only 2 items bought together (see table at 00:33 . So we need to generate rules for pair of items also. Thats why 2freq itemset is also used.
The reason taking only two frequent item bcoz we have to find which item is to placed left or right with which item.. We can find 3 frequent item but again we break that into two item set to find left and right item
Hi Sir, hope you are well. Thank you for your explanation, it really helped. I just want to point out that you forgot about the Cookies from the items.
Hello, Sir! What if I have a scenario wherein when I got to 2-item set, none is greater or equal to the given support threshold. what should be my next step then?

When should we calculate confidence of only 3-frequent item sets and when to calculate both 2 and 3 frequent item sets?
same doubt , got any clarification
Well explain very helpful

Then you should stop the process
Tq so much
Thank you sir
Best explaination!
what to do when support is not given can we take the value on our own
Pls make a vedio on Direct hashing and pruning and dynamic item set counting.
These two algorithm have not in any other youtube channel
Nice
Sir...Itemset count while calculating minimum support count should be 6, why are you taking it as 5?
It should be the number of transactions instead of itemset_count.
Minimum support count = minimum support * number of transactions, not itemset_count .. he was wrong in that one..
@@fugeratube1334 dude how we calculate no of transaction..
@@dkheart3474 u just have to count it... it's the total transactions occurred in this example their r 5 no. Of Transactions.
@@fugeratube1334 why he take cookies? in second item set
Thank you brother

I appreciate for ur explaination but, i would happy if u replied for the people who had doubt about cookies and other queries.
Min support should be 2.4?
Approx we can write 3
Sir can u solve the model question which is released the today. 18CS71
may i know what you're doing today? studying or in a job?
appreciate
Thank you
