Construction of FP Tree using Huffman Coding
In Data Mining the task of finding frequent pattern in large
databases is very important and has been studied in large scale.
Mining frequent patterns in transaction databases, time-series
databases many other kinds of databases has been studied
popularly in data mining research. This task is computationally
expensive, especially when a large number of patterns exist
and when there exists candidate set generation. In this study,
we propose a novel frequent pattern tree (FP-Tree) structure
using Huffman coding for storing compressed, crucial
information about frequent patterns, develop an efficient FPTree
based mining method. The FP-Tree Algorithm is an
alternative way to find frequent item sets without using
candidate generations, using a divide-and-conquer strategy.
Keywords: Data mining, Frequent pattern, Huffman coding, FP Tree, Candidate key, Binary tree.
