In this paper we have proposed a framework to deal with SVM model selection problem in dynamic environment. In dynamic environment, knowledge about a problem changes over time due to which static optimum values for yper-parameters may degrade the performance of the classifier. For this there ...

In this experiment, the Bayesian optimized SVM classifier was used to classify the spillway data in eight classes (e.i., Type I, Type II, Type III, Type IV, Type V, Type VI, Type VII, Type VIII). Deciding on a precise spillway type is only possible after economic analysis. Economic...
Adaptive Boosting (AdaBoost)(Hastie et al.2009): is a meta-classifier that works in conjunction with other learning algorithms. AdaBoost uses a weighted sum to combine the predicted output from other weak classifiers to output its final prediction. In particular, AdaBoost adaptively improves its ...

All the research studies that have done earlier are centered to get better accuracy in prediction level of BC using different Machine Learning (ML) algorithms. The earlier paper of the same study proposed comparative study chart of different supervised machine learning algorithm in which SVM found ...
In real-world applications, selecting the appropriate hyper-parameters for support vector machines (SVM) is a difficult and vital step which impacts the generalization capability and classification performance of classifier. In this paper, we analyze the distributing characteristic of hyper-parameters that...
