Spectral Variability in a Multilinear Mixing Model [PDF]
IGARSS 2018 - 2018 IEEE International Geoscience and Remote Sensing Symposium, 2018 We present a new method for spectral unmixing which takes both nonlinear mixing and spectral variability into account. This is accomplished by combining the multiple endmember spectral mixture analysis (MESMA) approach with the recently developed multilinear mixing model (MLM).

Spectral-based printer modeling and characterization [PDF]
Journal of Electronic Imaging, 2005 Spectral characterization involves building a model that relates the device dependent representation to the reflectance func- tion of the printed color, usually represented with a high number of reflectance samples at different wavelengths. Look-up table-based approaches, conventionally employed for colorimetric device char- acterization cannot be ...

A spectral model for multimodal redshift estimation [PDF]
2016 IEEE Symposium Series on Computational Intelligence (SSCI), 2016 We present a physically inspired model for the problem of redshift estimation. Typically, redshift estimation has been treated as a regression problem that takes as input magnitudes and maps them to a single target redshift. In this work we acknowledge the fact that observed magnitudes may actually admit multiple plausible redshifts, i.e.

Spectral goodness of fit for network models [PDF]
Social Networks, 2014 We introduce a new statistic, 'spectral goodness of fit' (SGOF) to measure how well a network model explains the structure of an observed network. SGOF provides an absolute measure of fit, analogous to the standard R-squared in linear regression.

Generalized spectral tests for the martingale difference hypothesis [PDF]
, 2006 This article proposes a test for the martingale difference hypothesis (MDH) using dependence measures related to the characteristic function. The MDH typically has been tested using the sample autocorrelations or in the spectral domain using the ...

Многомасштабная модель геодинамо: сопряжение крупномасштабной и мелкомасштабной подмоделей
Vestnik KRAUNC: Fiziko-Matematičeskie NaukiФормирование главного геомагнитного поля обеспечивается работой механизма гидромагнитного динамо — генерации магнитного поля движением проводящей среды. Динамо Земли (геодинамо) управляется конвекцией жидкого металла во внешнем ядре Земли.

Sensitivity experiments to mountain representations in spectral models
Annals of Geophysics, 2000 This paper describes a set of sensitivity experiments to several formulations of orography. Three sets are considered: a "Standard" orography consisting of an envelope orography produced originally for the ECMWF model, a"Navy" orography directly from the
