In this paper, we develop an automated and adaptive framework that aims to move active data to high performance storage tiers and inactive data to low cost/high capacity storage tiers by learning patterns of the storage workloads. The framework proposed is designed using efficient Markov chain correlation based clustering method (MCC), which can quickly predict or detect any changes in the current...
Utilizing the concept of hypothesis margins to measure the quality of a set of features has been a growing line of research in the last decade. However, most previous algorithms have been developed under the large hypothesis margin principles of the 1-NN algorithm, such as Simba. Little attention has been paid so far to exploiting the hypothesis margins of boosting to evaluate features. Boosting is...
Feature selection helps us to address problems possessing high dimensionality, retaining only those features that are most important for the classification task. However, traditional feature selection methods fail to account for imbalanced class distributions, leading to poor predictions for minority class samples. Recently, there has been a growing interest around the Area Under ROC curve (AUC) metric...
Intrusion detection systems (IDSs) are continuously evolving, with the goal of improving the security of computer infrastructures. However, one of the most significant challenges in this area is the poor detection rate, due to the presence of excessive features in a data set whose class distributions are imbalanced. Despite the relatively long existence and the promising nature of feature selection...
