Association Rule Mining Based Video Classifier with Late Acceptance Hill Climbing Approach
نویسندگان
چکیده
Video classification is an essential step towards video perceptive. In recent years, the concept of utilizing association rules for classification emerged. This approach is more efficient and accurate than traditional techniques. Associative classifier integrates two data mining tasks such as association rule discovery and classification, to build a classifier for the purpose of prediction. The accuracy of classification will be influenced by the choice of appropriate values for whatever thresholds are used. In this paper, we present an effective video classification technique which employs the association rule mining and examine the effect of varying the support and confidence thresholds on the accuracy of the proposed algorithm. Instead of two stage associative classification method, Total from Partial Classification technique integrates the association rule discovery and classification in a single processing step to reduce the cost of pruning. TFPC uses two enumeration trees such as Partial support tree (P-Tree) and Total support tree (T-Tree). TFPC algorithm first loads the input data into the P-tree structure to reduce the storage requirements. In the second stage, T-tree is used to hold the information regarding to frequent items. We proposed Late Acceptance Hill-Climbing (LAHC) method is to find the effective support and confidence coupled with TFPC. The LAHC method accepts the candidates with cost function better than the cost solution which were the current several iterations before. Experimental results show that the performance of classification accuracy can be significantly improved.

The effect of threshold values on association rule based classification accuracy
Classification Association Rule Mining (CARM) systems operate by applying an Association Rule Mining (ARM) method to obtain classification rules from a training set of previously-classified data. The rules thus generated will be influenced by the choice of ARM parameters employed by the algorithm (typically support and confidence threshold values). In this paper we examine the effect that this ...

Background and Aim: Total Knee Arthroplasty (TKA) aims to reduce the pain and improve the quality of life of patients with progressive osteoarthritis. When the indication of patients' disease is established, this type of surgery should be performed as soon as possible because patients' late attendance increases surgical complications. Therefore, identification of factors influencing the choice ...
متن کاملA Parameter-Free Associative Classification Method
In many application domains, classification tasks have to tackle multiclass imbalanced training sets. We have been looking for a CBA approach (Classification Based on Association rules) in such difficult contexts. Actually, most of the CBA-like methods are one-vs-all approaches (OVA), i.e., selected rules characterize a class with what is relevant for this class and irrelevant for the union of ...
متن کاملComparison of Acceptance Criteria in Randomized Local Searches
One key component of stochastic local search algorithms is the acceptance criterion that determines whether a solution is accepted as the new current solution or it is discarded. One of the most studied local search algorithms is simulated annealing. It often uses the Metropolis condition as acceptance criterion, which always accepts equal or better quality solutions and worse ones with a proba...

Data envelopment analysis (DEA) is a relatively new data oriented approach to evaluate performance of a set of peer entities called decision-making units (DMUs) that convert multiple inputs into multiple outputs. Within a relative limited period, DEA has been converted into a strong quantitative and analytical tool to measure and evaluate performance. In an article written by Toloo et al. (2009...
