{"product_id":"variable-selection-and-neural-networks-nabil-benoudjit-9783836495042","title":"Variable Selection and Neural Networks","description":"This book focuses particularly on the application of chemometrics in the field of analytical chemistry. In infrared spectroscopy for instance, chemometrics consists in the prediction of a quantitative variable (the obtention of which is delicate, requiring a chemical analysis and a qualified operator), such as the concentration of a component present in the studied product from spectral data measured on various wave-lengths or wavenumbers. In this book the author proposes a methodology in the field of chemometrics to handle the spectrophotometric data which are often represented in high dimension. To handle these data, a new incre-mental method (step-by-step) is proposed for the selection of spectral data using linear and non-linear regression. The author proposes, also, to improve the previous method by a judicious choice of the first selected variable, which has a very important influence on the final performances of the prediction. The idea is to use a measure of the mutual information between the independent and dependent va-riables to select the first one; then the previous incremental method (step-by-step) is used to select the next variables.\u003cbr\u003e\u003cbr\u003e\u003cb\u003eAuthor:\u003c\/b\u003e Nabil Benoudjit\u003cbr\u003e\u003cb\u003eISBN-10:\u003c\/b\u003e 383649504X\u003cbr\u003e\u003cb\u003eISBN-13:\u003c\/b\u003e 9783836495042\u003cbr\u003e\u003cb\u003ePublisher:\u003c\/b\u003e VDM Verlag Dr. Mueller E.K.\u003cbr\u003e\u003cb\u003eLanguage:\u003c\/b\u003e English\u003cbr\u003e\u003cb\u003ePublished:\u003c\/b\u003e 04\/08\/2008\u003cbr\u003e\u003cb\u003ePages:\u003c\/b\u003e 168\u003cbr\u003e\u003cb\u003eFormat:\u003c\/b\u003e Paperback\u003cbr\u003e\u003cb\u003eWeight:\u003c\/b\u003e 0.51lbs\u003cbr\u003e\u003cb\u003eSize:\u003c\/b\u003e 9.00h x 6.00w x 0.36d","brand":"Nabil Benoudjit","offers":[{"title":"Paperback","offer_id":47305558819071,"sku":"9783836495042","price":73.44,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0662\/2982\/9887\/files\/img_e1a534d9-b6d9-447e-825f-ac0472f9c2b9.jpg?v=1758831217","url":"https:\/\/www.whiterainbookhouse.com\/products\/variable-selection-and-neural-networks-nabil-benoudjit-9783836495042","provider":"WR Book House","version":"1.0","type":"link"}
