VectorRank (VR)

VectorRanks goal, to create a vector prediction machine that looks beyond purely indexical and quantitative information through VectorRanks algorithm. The performance of a classical linear vector predictor is limited by its ability to exploit only the linear correlation between the blocks. However, a nonlinear predictor exploits the higher order correlations among the neighboring blocks, and can predict edge blocks with increased accuracy. Experiments have shown several neural network architectures that can be used to implement a nonlinear vector predictor, including the multilayer perceptron (MLP), the (FL) network, and the radial basis function (RBF) network. Experimental results show that a neural network predictor can predict the blocks containing edges with a higher accuracy than a linear predictor.
