In this paper, a novel feature selection method is presented, which is based on Class-Separability (CS) strategy and Data Envelopment Analysis (DEA). To better capture the relationship between features and the class, class labels are separated into individual variables and relevance and redundancy are explicitly handled on each class label. Super-efficiency(More)
The complex mixed solution is a common material form in all walks of life. It was difficult to achieve the desired results if the complex mixed solution was detected by the traditional spectral analysis method. The hyperspectral technology was taken to detect the complex mixed solution to improve the signal to noise ratio of the spectrum by utilizing the(More)
Dynamic spectrum method extracts the absorbance of the artery pulse blood with some wavelengths. The method can reduce some influence such as measurement condition, individual difference and spectrum overlap. It is a new way for noninvasive blood components detection However, how to choose a dynamic spectrum extraction method is one of the key links for the(More)
To improve the efficiency and accuracy of the dynamic spectrum data processing, the method of single-trial estimation was adopted. First, the rising edge of the whole band PPG was extracted, which was calculated by averaging superimposed collected photoelectric plethysmography (PPG) at all wavelengths as a template per single pulse; Second, this template(More)
In the present paper, the authors proposed a method for component analysis of complex mixed solutions based on multidimensional diffuse reflectance spectroscopy by analyzing the information carried by spectrum signals from various optical properties of various components of the analyte. The experiment instrument was designed with supercontinuum laser(More)
In order to overcome the defects of overlapping spectrum and low signal-to-noise ratio in the analysis of the complex mixed solution with the traditional spectral method, the authors introduce hyperspectral technique to the analysis of complex mixed solution in the present article. The hyperspectral technique can use the information of the analytes carried(More)
The multi-dimensional diffuse transmittance spectrums were collected by the traditional near-infrared transmittance method combined with a scanning device, and then used for component analysis of the complex mixed solution. A xenon light, an electric control translation stage and a spectrometer were gathered to set up a device; Intralipid-20%, India-ink and(More)
Spatially offset visible-near-infrared (VIS-NIR) spectroscopy was used to analyze of chemical compositions of the scattering liquids in the visible and near-infrared region from 530 to 930 nm. An experimental setup was designed based on a supercontinuum white-light laser source, an electrically controlled translation stage, and a high-performance(More)
