Re: how to adjust the minimum support in itemset mining?

generally, if you set It too high you will find too many patterns while if you set It too low you may find millions of patterns and algorithms for itemset mining may become Very very slow. So generally, a good approach Is to start with a high value and then decrease the minimum support threshold unt...

Re: Eclat vs Apriori

Fpgrowth Is different. It Is a pattern growth algorithm. while Apriori and Eclat can generate candidates that dont exist in the data, fpgrowth does not which makes it much more efficient. It also uses a compact tree structure to store the database and its projections.

Re: Do you think AI can replace humans in ten years?

There Is indeed fast progress. I would say more like 40 or 50 years.

Re: could you implement pincer search?

this is an old algorithm. I do not have plan but If someone do it, i can include the code.

Re: Eclat vs Apriori

There could be situations where each algorithm is better but generally Eclat Is more efficient. The big problem of Apriori Is that it uses a breadth first search. Because of this it needs to keep at every moments two levels in memory (a level means itemsets having the same number of items that are c...

Re: could we use pattern mining for COVID19?

Yes, of course. If you want to analyze the genome of the COVID 19, it is possible. The data of many strains is public and can be downloaded. In my research team, we have used the SPMF software to apply various pattern mining algorithm to analyze COVID genome sequences. You can find some papers that ...

Re: Vertical and horizontal databases

In frequent itemset mining , an horizontal database is a database where each record is a transactions containing several items. A vertical database is a database where each record is an item containing a list of transactions. The two representations are equivalent. There are two ways of representing...
