apriori algorithm in data mining in hindi urdu, a priori algorithm with association rule mining

This apriori algorithm lecture explains what is apriori algorithm in data mining with example in hindi and urdu language.
This is 4th lecture of data mining tutorial for beginners in urdu and hindi series. In end of previsous lecture 3, exam question for bining method exampe was explained to handle noisy data, and today in this lecture, a priori algorithm in data mining is explained with example step by step. This lecture includes following points;
Table of Contents:
1. What is Apriori algorithm
2. How does Apriori algorithm work
3. Solving Apriori algorithm example
WRITTEN EXPLANATION OF TOPICS COVERED IN THIS DATA MINING TUTORIAL:
Q. what is Apriori algorithm ?
In simpler words, it is candidate generation and test approch
Q. How does Apriori algorithm work or what are steps Apriori algorithm ?
a) Scan database to get frequent items
b) Generate length k+1 candidates from k items
c) terminate when no frequent sets can be generated
Note: apriori algorithm in data mining is same as apriori algorithm in machine learning or data sciece or data warehouse,
so everyone can watch this video for apriori algorithm working principle.

Q1. Write the definition of apriori algorithm
Ans. Apriori is an algorithm for frequent item set mining and association rule learning over relational databases. It proceeds by identifying the frequent individual items in the database and extending them to larger and larger item sets as long as those item sets appear sufficiently often in the database.
Reference: Wikipedia
Q2.How does Apriori algorithm work?
Ans. Given a threshold , the Apriori algorithm identifies the item sets which are subsets of at least transactions in the database. Apriori uses a "bottom up" approach, where frequent subsets are extended one item at a time (a step known as candidate generation), and groups of candidates are tested against the data.
Reference: Wikipedia
Q3. Why Apriori algorithm is called Apriori?
Ans. Apriori algorithm is nothing but an algorithm that is used to find out patterns or co-occurrences between items in a data set. Apriori algorithm is called apriori because it uses prior knowledge of frequent item set properties. ... He started searching for ways to figure out patterns and relations between items

Q4. What is the advantage of Apriori algorithm in DM?
To improve the efficiency of level-wise generation of frequent itemsets, an important property is used called Apriori property which helps by reducing the search space. All subsets of a frequent itemset must be frequent(Apriori propertry).
