Methods, systems, and devices supporting epsilon (ε)-closure for frequent pattern (FP) analysis are described. Some database systems may analyze data sets to determine FPs. In some cases, the FP set may include a large number of semi-redundant patterns, resulting in significant memory or ...

EN我的NFA的开始状态(S0)有两个向S1和S2的传出epsilon转换，而S1和S2有进一步的转换，并且互不相交。
Calculate the epsilon closure of the initial state − The epsilon closure of a state includes all states reachable from that state using only epsilon moves.From q0, we can reach q1 with null (epsilon) move Therefore, the epsilon closure of q0 is {q0, q1}.The epsilon closure of the ...

A strict superclass of transformations having the required closure property is presented and discussed. The syntactical model that computes this class of transformations is the multi bottom-up tree transducer enhanced by epsilon transitions. An effective composition construction is proposed, which is ...
