Frequency of I3 at the first calculation should be 6

[@ayshaismail8798]

Yes and also I4 is 2

[@aryandani8664]

i know right? huddar what bro

[@vishalgr9526]

sir there is an error, according to the question there is only 2 'i4' but in the 1-item set the mentioned data frequency has 4 so just correct that part :)

[@joetomthomas3074]

@@MaheshHuddar 2 item sets I2 and I3 frequency is 4

[@sravanbathini4137]

@@MaheshHuddar nope even I3 are 6, but he only wrote 5 of them

[@RHAD-iy5fy]

and also i3 has an error the frequency is 6 not 5

[@Sweetheart-h5w]

Sir please continue the videos.... Complete other modules also... It's helping me a lot...

[@puneethcs6889]

Sir actually the 1item sets the item4 have frequency 2 and the item5 have also have frequency 2 but you write 4 is there it's wrong sir

[@Shalu_Gaming]

Sir but i3 is there in 6

Thank you! Really clear

I3 support is 6

[@nirmalkondreddy7176]

yes

[@kanesapillainitharshan189]

Also I4 support is 2

[@karanbhanushali6756]

how one can come to know minimum support is 2

[@user-nc7my2or4r]

confidence = Frq(x,y)/frq(x). So why is it divided by the number of items (N)? So, the confidence calculation is incorrect. Please correct me if I'm incorrect.

[@tanveersayyed561]

same confusion have come through Any conclusion

[@brams3955]

This video is well. But with the mistake you made, it spoiled everything. In my opinion, you need to redo it. :-)
But it was helpful

great video , how can we determine the value of support and confidence level during the real life example

[@tejapandruvada7164]

They will give during the exam

[@bhumikak4815]

Sir while calculating the support and confidence(initially) the frequency of which two items should be taken sir ??

[@swapnilkulkarni4760]

1 item set... value of i3 has to be 6

[@btol2421]

Sir,What If a transaction id contain more than one similar item should we consider that as one during frequency count
??

[@MaheshHuddar]

Consider two times

[@btol2421]

@@MaheshHuddar Sir and in Fp growth we should only consider once??

[@haibaraai1690]

Sir for subset creation part, how to know min support = 22% and min confidence = 50%

[@supriyabala6954]

Confidence will be given in question
And support they have given 2 in question so total items is 9
So 2/9 is 22😊
