Combination of classifiers is a promising direction for obtaining better classification systems. However, the outputs of different classifiers may have different scales and hence the classifier outputs are incomparable. Incomparability of the classifier output scores is a major problem in the combination of different classification systems. In order to avoid this problem, the measurement level ...

Due to increasing incidents of cyber attacks, building effective Intrusion Detection Systems (IDS) are essential for protecting information systems security, and yet it remains an elusive goal and a great challenge. Current IDS examine all data features to detect intrusion or misuse patterns. Some of the features may be redundant or low importance during detection process. The purpose of this s...

Standard signature verification (SV) systems are writer-dependent (WD), where a specific classifier is designed for each individual. It is inconvenient to ask a user to provide enough number of signature samples to design his WD classifier. In practice, very few samples are collected and inaccurate classifiers maybe produced. To overcome this, writer-independent (WI) systems are introduced. A g...

Solar mini-dimmings can be detect in the Extreme Ultra-Violet coronal eruptions. Here, sequences of 171_A images taken by Solar Dynamic Observatory/Atmospheric Imaging Assembaly on 13 June 2010 are used. In this special day, both of coronal mass ejection and prominence were observed. The average velocities and accelerations of 500 mini-dimmings which were detected using on feature based classif...
