IN this paper, we tend to introduce and study the minimum consistent set cowl (MCSC) drawback that finds several applications in common data processing tasks, providing a minimization read of knowledge mining. Given a finite ground set X and a constraint t, the MCSC drawback finds the minimum number of consistent subsets that called X, wherever a set of X is consistent if it satisfies t. The MCSC drawback provides a way of generalizing the traditional set covering drawback [15] , wherever a set of X is consistent if it's a given set. completely different from set covering, in typical MCSC instances the consistent subsets are not expressly given and that they got to be generated. For example, minimum pack partition (MCP), a twin drawback of graph coloring, are often thought of as Associate in Nursing MCSC instance, where a set is consistent if it forms a pack and also the cliques don't seem to be given as input. Scope& Importance Data mining applications.-several common data processing tasks are often developed as MCSC instances. As an utilization of the MCSC drawback in rule learning, the minimum rule set (MRS) drawback finds a complete and consistent set of rules with the minimum cardinality for a given set of tagged examples. The completeness and consistency constraints need correct classifications of all the given examples. With the goal of minimizing model complexness, the MRS drawbacks are often motivated from each information classification and information description applications. The MRS drawback may be a typical MCSC instance, wherever a set is consistent if it forms an identical rule, i.e., the bounding box of the set contains no examples of alternative categories. As a distinguished bunch model, k-clustering generates k clusters minimizing some objective, like most radius as within the k-center drawback or most diameter as within the pair wise bunch drawback [4], [12] . The radius of a cluster is that the most distance between the centre of mass and the points within the cluster. The diameter is that the most distance between any 2 points within the cluster. Since the number of clusters is commonly laborious to work out before hand, converse k-clustering are often a a lot of applicable bunch model, wherever a most radius or diameter threshold is given and also the variety of clusters k is to be decreased . The converse k-center and converse pair wise bunch issues area unit both MCSC instances, wherever a set is consistent if it forms a cluster satisfying a given distance constraint. Frequent pattern mining has been a trademark of knowledge mining. whereas mining potency has been greatly improved over the years, interpretability instead became a bottleneck to its winning application. As a noted drawback, the irresistibly large number of generated frequent patterns containing redundant info area unit if truth be told "inaccessible knowledge" that must be any mined and explored. Thus, report of enormous collections of patterns within the pursuit of usability has emerged as a vital analysis problem. The converse k-clustering models mentioned on top of as well as another MCSC formulations seem to be a reasonable and promising approach towards this drawback. The goal of knowledge mining is to extract attention-grabbing patterns [11] . Knowledge should be concise and ideally human-comprehensible, providing a generalization of knowledge. The deserves of minimalist (detailed in Section 3) of classification models are well mentioned and with success used [43], [33]. Many common data processing tasks are often viewed as a decrease process. The MCSC drawback we tend to study formalizes such a decrease views. within the drawback, the constraint t isused to check the "consistency" of partial information, i.e., subsets of the ground set X. every qualified consistent set corresponds to a motivating pattern, i.e., a rule or a cluster of certain size. The goal is to attenuate the model complexness in terms of variety of patterns. Related work A generic formula-several sensible MCSC instances feature antimonotonic constraints, i.e., constraints with the downward closure property, underneath that any set of a consistent set is additionally consistent. Antimonotonicity are often used to gain potency in finding MCSC instances, similar to the cases of frequent pattern mining, consecutive pattern mining, and topological space bunch [20] . We style a generic formula CAG which will be wont to solve Associate in Nursing MCSC instance that exhibits an antimonotonic constraint. CAG starts by constructing a greatest optimum partial answer, so performs Associate in Nursing example-driven specific-togeneral search on a dynamically maintained bipartite assignment graph to at the same time learn a tiny low consistent set cowl. We conjointly extend the applicable territory of CAG by introducing pivot antimonotonicity that generalizes antimonotonicity. We use the separate converse k-center and also the star partition issues as examples to indicate however CAG will be tailored to unravel such MCSC instances .Set covering. the standard set covering drawback [15] finds the minimum variety of subsets from a given collection of subsets that cowl a given ground set.
