Journal ArticleDOI
Development and characterisation of a new fluorescence sensor for online monitoring of bioprocesses
Jan C. L. König,Tobias Steinwedel,Dörte Solle,Patrick Lindner,Ingo de Vries,Thorleif Hentrop,Michael Findeis,Gernot Thomas John,Thomas Scheper,Sascha Beutel +9 more
TL;DR: A newly developed robust online fluorescence sensor that facilitates the analysis of fluorescence measurements is presented that was constructed to measure only the three most important biologic fluorophores, resulting in a significant data reduction compared to conventional a 2-D fluorescence spectrometer.
Journal ArticleDOI
A robust regression approach for spectrophotometric signal analysis
TL;DR: A novel fusion strategy named selection‐based strategy (SBS) is proposed that provides as output the estimate obtained by the regression algorithm (included in the ensemble) characterized by the highest expected accuracy in the region of the feature space associated with the considered model.
Journal ArticleDOI
Rapid determination of lumbrokinase potency in the earthworm extract intermediate by near-infrared spectroscopy
Gao Lingling,Tongtong Li,Lian Li,Li Zhen,Lei Nie,Zhou Haiyang,Zhongyu Sun,Ye Suyan,Ruichen Liu,Hengchang Zang +9 more
TL;DR: It is demonstrated that NIR analysis techniques are a potential tool for rapidly determining lumbrokinase potency in earthworm extract intermediate and the variable selection combination method was investigated to optimize the modeling variables and improve the predictive abilities of the NIR model.
Proceedings ArticleDOI
Determination of glucose concentration from near infrared spectra using least square support vector machine
TL;DR: In this paper, a multivariate calibration model for determination of glucose concentration from near infra-red (NIR) spectra is presented. But the proposed model is based on least squares support vector regression (LS-SVR).
Journal ArticleDOI
Investigation of adulteration of sunflower oil with thermally deteriorated oil using Fourier transform mid-infrared spectroscopy and chemometrics
TL;DR: In this article, Fourier transform infrared spectroscopy combined with multivariate analysis methods was used to monitor the adulteration of pure sunflower oil (SO) with thermally deteriorated oil (TDO).

Neural Networks: A Comprehensive Foundation
TL;DR: Thorough, well-organized, and completely up to date, this book examines all the important aspects of this emerging technology, including the learning process, back-propagation learning, radial-basis function networks, self-organizing systems, modular networks, temporal processing and neurodynamics, and VLSI implementation of neural networks.

Classification and regression trees
TL;DR: The methodology used to construct tree structured rules is the focus of a monograph as mentioned in this paper, covering the use of trees as a data analysis method, and in a more mathematical framework, proving some of their fundamental properties.

Nearest neighbor pattern classification
Thomas M. Cover,Peter E. Hart +1 more
TL;DR: The nearest neighbor decision rule assigns to an unclassified sample point the classification of the nearest of a set of previously classified points, so it may be said that half the classification information in an infinite sample set is contained in the nearest neighbor.
