Web8. nov 2014 · The definition of a span is "the maximum number of consecutive elements X [j] immediately preceding X [i] and such that X [j] ≤ X [i] ", but the algorithm appears to add one to the result. For X [0] (no immediately preceding smaller elements) it is 1. For X [1] (no immediately preceding smaller elements) it is 1. Web1. jan 2014 · 7.3.1 Overview. Based on the LQS-Tree Footnote 1 used in [], the proposed HUS-Span algorithm traverses the tree in a depth-first way.Figure 7.1a shows the LQS-Tree of q-SDB DB in Table 7.1a. In the LQS-tree, each node t consists of its sequence and its utilities v(t).The root is an empty sequence, and HUS-Span algorithm begins the mining process … WebThe Prefix Span algorithm does not generate candidate sets during the mining process, which performance is much higher than other series of patterns mining classic algorithms. According to the characteristics of the algorithm, and based on the shortcomings of the al-gorithm, the Prefix strategy is modified to reduce the frequent exchange ... conversations among masters
