semi-supervised k-means clustering is proposed for outlier detection in mammogram classification. Initially the shape features are extracted from the digital mammograms‚ and k-means clustering is applied to cluster the features‚ the number of clusters is equal with the number of classes. The clusters are compared with original classes‚ the wrongly clustered instances are identified as outliers and they are removed from the feature space. A novel Genetic Association Rule Miner (GARM) is applied with

Question 1: Why should a manger know about research when the job entails managing people‚ products‚ events‚ environments‚ and the like? Answer: Research simply means a search for facts – answers to questions and solutions to problems. It is a purposive investigation. It is an organized inquiry. It seeks to find explanations to unexplained phenomenon to clarify the doubtful facts and to correct the misconceived facts. Research is the organized and systematic inquiry or investigation which provides

algorithm is based on k-means algorithm and. The main procedure includes three stages‚ writing the code in matlab‚ converting the code from matlab to VHDL‚ implementing the code in VHDL onto FPGA board. Firstly the given data of neurons is grouped into clusters using k-means algorithm in matlab to identify number of neurons in the given data and timing analysis at which ach neuron fires .Then‚ the parameters which are used in the matlab code are used and converted into VHDL using as. After that‚ the code

They provide an opportunity for researchers to discover unanticipated information regarding the domain of study. However‚ they are problematic for processing since they are unstructured questions to which

TABLE OF CONTENTS 1.0 INTRODUCTION Among the factors of production‚ the human resource element of any organization is most strategic and paramount. Performance appraisal therefore‚ is an important means by which organizations improve their chances of attaining their key operational goals. Employees‚ who know what and how much is expected of them‚ are likely to be more effective than those who are unclear about their role. It is in the light of this that organizations these days are becoming
