The group member Xihui Bian attended the twelfth Winter Symposium on Chemometrics (WSC12) on February 24-28, 2020, which was held at recreation center “Volzhskie Dali”, located on the bank of the Volga river in the suburbs of city Saratov.
The conference is co-sponsored by Saratov State University and the Russian Chemometrics Society. Natalia Burmistrova is the Co-chairmen and Yulia Monakhova is the Secretary. The member of the organizing committee includes Dmitry Kirsanov, Sergey Kucheryavskiy, Alexey Pomerantsev, Oxana Rodionova, Tatyana Rusanova. About 50 scientists contributed to the scientific part of the symposium with 5 lectures, 29 oral and 18 poster presentations.
Douglas Rutledge, Emiritus Professor at AgroParisTech, Paris, France, gave a lecture titled “Novel extensions and applications of Common Components Analysis in chemometrics”. Alejandro C. Olivieri, Professor at National University of Rosario, Argentina, gave a lecture titled “A general view of multi-way data processing and its advantages”. Beata Walczak, Professor at University of Silesia in Katowice, Poland, gave a lecture titled “Chemometrics in chromatography”.
Alexey Pomerantsev, professor of the Semenov Institute of Chemical Physics of the Russian Academy of Sciences, gave a report entitled "SIMCA. Decision Rules". This report summarizes the development of SIMCA and compares Simple SIMCA, Alternative SIMCA, Combined Index SIMCA and Data Driven SIMCA. It is concluded that data-driven SIMCA is the best method. Oxana Rodionova, professor from the Semenov Institute of Chemical Physics, Russian Academy of Sciences, presented a report entitled "Calculation of total distance and outlier detection in the projection regression models". She proposed a new method for outlier detection, which can overcome "masking" effect. It was published in the journal of American Chemical Society <Analytical Chemistry> in 2020. Dmitry Kirsanov, professor of St. Petersburg State University, Russia, gave a report entitled "Analytical performance characterization of potentiometric multisensor systems", which refers to " Analytical figures of merit: from univariate to multivariate calibration”, including the calculation method of sensitivity, analysis sensitivity, selectivity, detection limit and quantification limit value. He explores the use of these indicators in 4 practical cases of potential measurement multi-sensor system. Federico Marini, professor of the University of Rome, Italy, gave a report titled "Advanced approaches for the analysis of multi-block data". The report mainly describes Sequential and Orthogonalized PLS-Covariance Selection, So- CovSel), sequential preprocessing through ORThogonalization (SPORT), and locally weighted- sequential and orthogonalized partial least squares (Locally weighted SO-PLS). Sergey Kucheryavskiy, associate professor of the University of Aalborg, Denmark, gave an oral report entitled "Procrustes cross-validation: reboot to strap validation again", which proposed that the uncertainty of the sample to sample be determined by calculating the angle between PC spaces to generate new data. This proposes a new cross-validation method.
The prize for best presentation given by a young chemometrician was given to (Brazil). He received a voucher for free participating in CAC 2020 from the CAC organising committee. The first prize for the best poster presentation took Pavel Pidenko (Russia). He was awarded with free participation in International School of Chemometrics ISC-2020. The second (Skvortsov Alexej) and third (Ashina Julia) prizes have been awarded with books and useful IT-equipment.
Xihui Bian of our research group gave an oral report entitled " Ensemble modeling for the spectral analysis of complex samples ". She also introduce the 20th biennial meeting of the International Council for NIR Spectroscopy (ICNIRS), which will be held from October 17th to 21st 2021 in Beijing, China.
