Reversed Spectral Hashing.
Hashing is emerging as a powerful tool for building highly efficient indices in large-scale search systems. In this paper, we study spectral hashing (SH), which is a classical method of unsupervised hashing. In general, SH solves for the hash codes by minimizing an objective function that tries to preserve the similarity structure of the data given. Although computationally simple, very often S...

متن کاملLight-induced spectral diffusion in single self-assembled quantum dots
Small ensembles of In0.55Al0.45As self-assembled quantum dots have been studied at low temperatures using near-field scanning optical microscopy. We observe spectral diffusion in individual quantum dot luminescence lines. The phenomenon increases in magnitude with optical power density, but is not visible at low powers. We believe the spectral diffusion to be caused by long time-scale trapping ...
متن کاملA New Approach for Olive (Arbequina cv.) Micropropagation: Effect of Dikegulac, Light and Carbon Source
Micro-propagation of olive provides the possibility of producing clones of native plants with appropriate attributes and mass reproduction in short period of time, compared to conventional methods. Apical dominance in olive explants limits the growth of lateral branches in vitro. The effect of Woody Plant Medium (WPM), Olive Medium (OM) and Murashig and Skoog (MS) with carbohydrate source (mann...
متن کاملSpectral methods for voice source parameters estimation
A spectral approach is proposed for voice source parameters representation and estimation. Parameter estimation is based on decomposition of the periodic and the aperiodic components of the speech signal, and on spectral modelling of the periodic component. The paper focusses on parameters estimation for the periodic component of the glottal ow. A new anticausal all-pole model of the glottal ow...
