therefore a large amount of research is being done. The problem is tackled by preprocessing the data using wrapper-based random oversampling. Wrapper is a preprocessing approach that makes use of system (classifier) feedback to guide preprocessing...

In this study the feasibility of using VIS/NIR spectroscopy along with chemometrics was investigated to predict quality parameters (pH, TSS and firmness) of pomegranate fruit in a nondestructive manner. The effects of different pre-processing...

point for any web mining process. Thus, the quality of results strongly depends on the quality of input data. In this paper, the result of our scenario-based experiment in preprocessing log data for analyzing user behavior is presented. The proposed...

Abstract—Pre-processing is necessary for many applications

before data transmission. In this paper, signal sparsity variations

due to some pre-processing steps such as...
