Many methods of hyperspectral data classification require the adjustment of learning parameters for their success. To this end, one may fix the learning parameters, offer a functional-based parameter decay, or use a step-wise decrement of the learning parameters after a fixed number of training steps. Each of the three methods described rely on the expertise of user and do not necessarily lend themselves...
Forecasting applications on the stock market attract much interest from researchers in the artificial intelligence field. The problem tackled in this study concerns predicting the direction of change of stock price indices, formulated in terms of binary classification. We use gene expression programming to evolve pools of binary classifiers and investigate several approaches to construct ensembles...
In this paper, a new framework to build an adaptive classifier is introduced. At first, a clustering algorithm, density-based spatial clustering of applications with noise (DBSCAN) is applied to a set of sample data to form initial set of clusters. The clusters are represented as classes. Using support vector machine (SVM), a classifier model is generated. In real world application, data comes in...
