APRIORI Algorithm Professor Anita Wasilewska Lecture Notes The Apriori Algorithm: Basics The Apriori Algorithm is an influential algorithm for mining frequent itemsets for boolean association rules. Key Concepts : • Frequent Itemsets: The sets of item which has minimum support (denoted by Li for ith-Itemset). • Apriori Property: Any subset of frequent itemset must be frequent. • Join Operation: To find Lk ‚ a set of candidate k-itemsets is generated by joining Lk-1 with itself. The Apriori

Introduction RSA Algorithms RSA stands for Rivest-Shamir-Adleman algorithm was invented on 1977 which is mostly used public-key cryptosystem. It was designed by Ron Rivest‚ Adi Shamir‚ and Leonard Adleman (Milanov 2009). This is the 1st crypto system which used two different keys to encrypt and decrypt the messages. In this cryptosystem it uses public key to encrypt and private key to decrypt the messages. Public key can be shared with everyone but the private key has to be with the person who

In the assignment I will be evaluating how Marxism and Feminism fit into the statistic I have in P3 and how I think they fit into them. I will also be evaluating how good my statistic I found was and the strengths and weakness’ that they have and then coming to a conclusion. The statistics that I found where based on infant mortality and life expectancy where I compared them to two different areas to see the difference. Due to me getting results from different years I believe that my evidence was
