Numerous class labels associated with each data instance is the main feature of any multi-label classification (MLC) problem. Correct prediction of class labels related to any test data is a big challenge in this domain. MLC can be applied in many fields such as personality prediction, cancer prognosis prediction, image annotation etc. In this paper(MLC-LR), we have employed problem transformation method for solving MLC. The proposed method uses initially clustering in the feature space. It is then followed by FP-growth algorithm for finding the relationship between labels. Once the desired clusters are obtained, then normalization of data associated with each cluster is performed. Also logistic regression is then applied over the normalized data for each particular cluster pertaining to all labels. When a new instance arrives in the testing phase, immediately the nearby cluster is identified by means of Euclidean distance metric as the measure. Rules related to label space for the nearby cluster is extracted to check for hypothesis of each antecedent label. If the calculated value is higher than a predefined threshold, it is assumed that both antecedent and consequent labels as the estimated labels for that test instance.
