Filter Feature Selection for Unsupervised Clustering of Designer Drugs Using DFT Simulated IR Spectra Data
TL;DR: In this paper, the authors explore the application of unsupervised forensic testing of novel psychoactive substances (NPSs) for forensic testing/analysis techniques, and explore their application in the field of forensic analysis.
Utilisation de la spectroscopie proche infrarouge comme un outil PAT pour la quantification de substances en solution
TL;DR: In this article, the authors present an outil analytique particulierement approprie pour la mise en place du PAT, which permet de realiser des analyses rapides, non destructives, sans preparation and sans contact.

High speed precision weighing of pharmaceutical capsules
TL;DR: In this paper, the capsule capacitance profile was correlated with capsule weight with correlation coefficient exceeding 0.999 and the mean precision was in the range from 1 mg to 3 mg, depending on the size of the capsule and was significantly lower than the 5% weight tolerances usually used by the pharmaceutical industry.

Fast discrimination of chocolate varieties using near infrared spectroscopy
TL;DR: In this article, the use of noncontact near infrared spectroscopy (NIRS) technology employing a diffuse reflection fiber optic probe for discrimination of chocolate varieties is presented, where 120 samples of 8 typical varieties of chocolate are selected randomly, and the samples are scanned in diffuse reflectance mode by a cooled InGaAs array spectrometer (950-1700 nm).

NIR spectroscopy for monitoring of the critical manufacturing steps and quality attributes of paliperidone prolonged release tablets
TL;DR: In this article , a Partial Least Squares (PLS) method has been developed taking into account the domain between 1350 and 1550nm of the 1st Savitzky-Golay derivatised spectra, with a low root mean square error of cross-validation of 6.7, offering a real time overview of the homogenisation process.

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.
