Creation In VBNET Using Barcode drawer for VS NET Control to generate, create ECC200 image in LVF The Las Vegas lter (LVF) algorithm employs an alternative generation procedure that of choosing random feature subsets, accomplished y the use of a Las Vegas algorithm [212] An outline of LVF is given in Figure 49 Initially the best feature subset is considered to be the entire conditional feature set A feature subset is randomly chosen; if the subset has a smaller cardinality than the current best and its inconsistency rate is less than or equal to a threshold , it is considered to be the new best subset Here the inconsistency count is de ned as the sum of the number of inconsistent objects minus the number of inconsistent objects with the most frequent class label.

For example, if there are n inconsistent objects for a 2-class dataset, c1 such objects belong to class 1, c2 to class 2, then c1 + c2 = n If the largest of these is, say, c1 then the inconsistency count will be n c1 The inconsistency rate is simply the sum of all inconsistency counts divided by the number of objects Every time a better subset is encountered, it is outputted Once the maximum number of iterations has been reached, the loop terminates and the algorithm returns the best subset found overall A problem with this approach is that it will tend to take longer to locate an optimal subset than algorithms that employ heuristic generation procedures Additionally, when datasets are huge, checking the consistency of the dataset takes a long time.

Returning to the example, LVF randomly chooses feature subsets from among the six features present, such as the subset {a, b, c} For class 1 there are 3 inconsistent objects, for class 2 there are also 3, so the inconsistency count will be (6 3)/12 = 1 If no inconsistency is allowed ( = 0), then this subset will not 4 be kept Given suf cient time, the algorithm should eventually reach the subset {a, d, f }, which is the smallest subset that produces the required inconsistency rateRelated: .

This algorithm requires no thresholds in order to function the search for the best feature subset is topped when the resulting subset entropy is equal to that of the entire feature set. For consistent data the nal entropy of the subset will be zero. Interestingly any subset with an entropy of 0 will also have a corresponding rough set dependency of 1. Returning to the example dataset, EBR rst evaluates the entropy of each individual attribute: Subset {a} {b} {c} {d} {e} {f } Entropy 0.8885861 0.9543363 0.9543363 0.8885860 0.8650087 0.6186034.Related:
