The problem was approached as the ranking of atom types with the Bradley\u2010Terry (BT) model, and as the regression of the Fukui function. Random Forests (RF) were trained to predict the condensed Fukui function, to rank atoms in a molecule, and to classify atoms as high\/low Fukui function. Atomic descriptors were based on counts of atom types in spheres around the kernel atom. The BT coefficients assigned to atom types enabled the identification (93\u201394\u2009% accuracy) of the atom with the highest Fukui function in pairs of atoms in the same molecule with differences \u22650.1. In whole molecules, the atom with the top Fukui function could be recognized in ca. 50\u2009% of the cases and, on the average, about 3 of the top 4 atoms could be recognized in a shortlist of 4. Regression RF yielded predictions for test sets with R<jats:sup>2<\/jats:sup>=0.68\u20130.69, improving the ability of BT coefficients to rank atoms in a molecule. Atom classification (as high\/low Fukui function) was obtained with RF with sensitivity of 55\u201361\u2009% and specificity of 94\u201395\u2009%.<\/jats:p>","DOI":"10.1002\/minf.201500113","type":"journal-article","created":{"date-parts":[[2015,11,24]],"date-time":"2015-11-24T12:59:19Z","timestamp":1448369959000},"page":"62-69","source":"Crossref","is-referenced-by-count":14,"title":["Machine Learning Estimation of Atom Condensed Fukui Functions"],"prefix":"10.1002","volume":"35","author":[{"given":"Qingyou","family":"Zhang","sequence":"first","affiliation":[]},{"given":"Fangfang","family":"Zheng","sequence":"additional","affiliation":[]},{"given":"Tanfeng","family":"Zhao","sequence":"additional","affiliation":[]},{"given":"Xiaohui","family":"Qu","sequence":"additional","affiliation":[]},{"given":"Jo\u00e3o","family":"Aires\u2010de\u2010Sousa","sequence":"additional","affiliation":[]}],"member":"311","published-online":{"date-parts":[[2015,11,24]]},"reference":[{"doi-asserted-by":"publisher","key":"e_1_2_7_1_2","DOI":"10.1063\/1.1700523"},{"unstructured":"IUPAC Compendium of Chemical Terminology 2006 URL: http:\/\/old.iupac.org\/goldbook\/FT07039.pdf.","key":"e_1_2_7_2_2"},{"doi-asserted-by":"publisher","key":"e_1_2_7_3_2","DOI":"10.1021\/ja00326a036"},{"doi-asserted-by":"publisher","key":"e_1_2_7_4_2","DOI":"10.1021\/ja00279a008"},{"doi-asserted-by":"publisher","key":"e_1_2_7_5_2","DOI":"10.1021\/ci200029y"},{"doi-asserted-by":"publisher","key":"e_1_2_7_6_2","DOI":"10.1021\/cr100149p"},{"doi-asserted-by":"publisher","key":"e_1_2_7_7_2","DOI":"10.1021\/jo970353p"},{"doi-asserted-by":"publisher","key":"e_1_2_7_8_2","DOI":"10.1021\/jp905885y"},{"doi-asserted-by":"publisher","key":"e_1_2_7_9_2","DOI":"10.1021\/jp9034584"},{"doi-asserted-by":"publisher","key":"e_1_2_7_10_2","DOI":"10.1021\/ie400066x"},{"doi-asserted-by":"publisher","key":"e_1_2_7_11_2","DOI":"10.1021\/ie102034c"},{"doi-asserted-by":"publisher","key":"e_1_2_7_12_2","DOI":"10.1021\/ci034228s"},{"doi-asserted-by":"publisher","key":"e_1_2_7_13_2","DOI":"10.1016\/j.chemolab.2014.03.011"},{"author":"Popelier P.
