How FP-Growth algorithm works. I'm unable to understand the prefix and suffix terms in this algorithm. Let says the database

TID List of items

T100 I1, I2, I5

T200 I2, I4

T300 I2,I3

T400 I1,I2,I4

T500 I1,I3

T600 I2,I3

T700 I1, I3

T800 I1,I2,I3, I5

T900 I1, I2, I3

From the above transaction how FP-Growth finds the frequent itemsets.

Hi, explaining the whole algorithm would take a lot of time.

So I recommend to read this chapter from the book of Tan & Kumar:

It is free to read and has some example about FPGrowth. I think it can help you to understand it.
