Thank You your video is excellent.You are a very good teacher .I dint understand this at first but with your detailed explanation I am able to solve.Thank You very much appreciate it.
t1= a,c,d t2= b,c,e t3= a,b,c,e t4= b,e For this transaction database a-projected conditional FP tree is like c:2 (adding the support for two c from two different subtrees). Here the answer works fine keeping consistency with the transaction database. But the example you explained, there for I3 projected conditional FP tree you didn't add two I1s to make it I1:4 since they are from two different subtrees. It works here but not why to the example I mention above? Please answer.
Very glad to hear from u... Thank u... Watch Top 90 Data Structures MCQs in the following link... ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-i2LTAJhkFf8.html
bro bro bro hum ese hi kahi kuch bhi ni likh skte like as you said ki i1 ya i3 kisi ko bhi pehle likh lo ni bro i1 isliye pehle aya kuki first come first serve ke tehhat i1 ko pehle serve kiya jayega as a rule of first come first serve than 13 ki baari ayegi. iske piche reason tha socha bta du baaki grt work.

There is something odd. You create association rules with FP-growth method but take the support counts from Apriori method solution. Is there any way to find out the support counts of itemsets by looking at the frequent patterns generated with FP-growth method? Edit 1: You use the table for the support counts of {I1,I2}, {I1,I5}, {I2,I5} but didn't explain how to use the frequent patterns generated to find the support count of I1, I2, and I5 alone. Edit 2: I believe we can take it from the tree we created, not the table. Thank you for the video but you may want to add an explanation for this part.
yea. u can get the support count from conditional database (table) given in this video from @11:20 to 19:45. U can get the required frequent item set count from the table.anyway i have taken correct values for generating association rules😊.
Actually 2 frequent sets(I1,I2,I3 and I2,I1,I5) are to be taken for last step. I explained by taking one set. Same thing to be proceed for the other set too.
how do you find the minimum sup & conf? i'm searching everywhere and don't find any answer, "let suppose min sup is 2" without any explanation how do you find this "2"
Minimum support is a requirement to find frequent itemsets. It is not supposed to calculate. If it is not given in problem, then you have to take one assumption and solve it.
at 19:00 if the minimum support is 3 what would be the conditional fp tree for I3,becoz if it is reached from two sides of the tree,then the I2 obtained from right side will have value 2 and from left side also it will be 2 ,so now as you said we can not combine items if they are on different sides of null node so without combining their minimum support is 2 in left also and right also,which is less than minimum support 3(assumed new minimum support).so now what would be the conditional fp tree for I3,can we still include I2 in its conditional fp tree?
For classification algorithm, we have evaluation metrics like F1 score, Accuracy and ROC. for FP growth and Apriori algorithms what are the evaluation metrics?
