Despite numerous studies during the last decade speech emotion recognition is still the task of limited success. Great efforts were made for extending emotional speech feature sets and selecting the most effective ones, proposing multi-stage and multiple classifier based classification schemes, and developing multi-modal speech emotion recognition technique. Nevertheless, the reported emotion recognition...
One of the problems in the analysis of the set of images of a moving object is to evaluate the degree of freedom of motion and the angle of rotation. Here the intrinsic dimensionality of multidimensional data, characterizing the set of images, can be used. Usually, the image may be represented by a high-dimensional point whose dimensionality depends on the number of pixels in the image. The knowledge...
This paper deals with a method, called locally linear embedding (LLE). It is a nonlinear dimensionality reduction technique that computes low-dimensional, neighborhood-preserving embeddings of high-dimensional data and attempts to discover a nonlinear structure (including manifolds) in high-dimensional data. In practice, the nonlinear manifold learning methods are applied in image processing, text...
