Hierarchical orthogonalization of descriptors
International Journal of Quantum Chemistry, 1997A novel hierarchical orthogonalization procedure is described for a set of partially ordered molecular descriptors to be used in making statistical correlations within a given data set.

The Dimensionality Of Psychopathology Descriptors
Multivariate Behavioral Research, 1981This study identified five stable dimensions that judges utilized in making similarity judgments of a set of 26 psychopathology descriptors from a diverse domain representing traditional psychopathology descriptions such as lay labels, and diagnostic categories from the second edition of the Diagnostic and Statistical Manual (DSM II), as well as ...

A unifying framework of steady-state Kalman filtering, smoothing and prediction for descriptor systems is presented by using the innovation analysis method in the time domain. The descriptor Kalman estimators are presented on the basis of the autoregressive moving-average innovation model and white-noise estimators.

we study the feature set for object recognition problem, and use human detection as a test case. We propose two improvements based on HOG model which are Spatial Selective Method and Multi-level Method. In Spatial Selective One, we use HOG descriptor to extract feature vector from image window, but we shorten the feature vector size by eliminating less

A nested motion descriptor is a spatiotemporal representation of motion that is invariant to global camera translation, without requiring an explicit estimate of optical flow or camera stabilization. This descriptor is a natural spatiotemporal extension of the nested shape descriptor [2] to the representation of motion.

This section reviews the molecular shape descriptors developed by Amoore, Allinger, Simon et al. and Testa and Purcell. The illustrative examples discussed refer to the odour similarity and cardiotoxic aglycones. One has stressed the methods based on the reference structure because, correctly formulated, these methods seem to offer promising ...
