We extend the nearest prototype classifier to a generalized nearest prototype classifier (GNPC). The GNPC uses "soft" labeling of the prototypes in the classes, thereby encompassing a variety of classifiers. Based on how the prototypes are found we distinguish between presupervised and postsupervised GNPC designs. We derive the conditions for optimality (relative to the standard Bayes error rat...

We propose new audio features that can be extracted from bass lines. Most previous studies on content-based music information retrieval (MIR) used low-level features such as the mel-frequency cepstral coefficients and spectral centroid. Musical similarity based on these features works well to some extent but has a limit to capture fine musical characteristics. Because bass lines play important ...

Pearce (2011) provides a positive and interesting response to our article on time series analysis of the influences of acoustic properties on real-time perception of structure and affect in a section of Trevor Wishart’s Red Bird (Dean & Bailes, 2010). We address the following topics raised in the response and our paper. First, we analyse in depth the possible influence of spectral centroid, a t...

It has been reported that vocal emotion recognition is challenging for cochlear implant (CI) listeners due to the limited spectral cues with CI devices. As the mechanism of CI, modulation information is provided as a primarily cue. Previous studies have revealed that the modulation components of speech are important for speech intelligibility. However, it is unclear whether modulation informati...

The asymmetric unit of the title compound, C(19)H(19)ClO(4), contains two independent mol-ecules. The dihedral angles between the benzene rings are 63.41 (8) and 61.41 (9)°. Adjacent mol-ecules of different types are inter-connected in pairs through π-π inter-actions between their central benzene rings [centroid-centroid separation = 3.801 (2) Å, inter-planar spacing = 3.605 (2) Å, centroid shi...

The crystal structure of the title compound, deca-methyl-cobaltocene, [Co(C(10)H(15))(2)], has been determined. High-quality single crystals were grown from a cold saturated hexa-methyl-disiloxane solution. The structure is related to the manganese and iron analogs. The molecule has D(5d) symmetry, with the Co atom in a crystallographic 2/m position. The cobalt-centroid(C(5)) distance is 1.71Å ...
