(E)-N,N-Diethyl-2,6-diisopropyl-4-[2-(4-nitro-phen-yl)ethen-yl]aniline.
Wink C, Schollmeyer D, Detert H. Wink C, et al. Acta Crystallogr Sect E Struct Rep Online. 2013 Nov 20;69(Pt 12):o1785-6. doi: 10.1107/S1600536813030948. eCollection 2013 Nov 20. Acta Crystallogr Sect E Struct Rep Online. 2013. PMID: 24454228 Free PMC article.
Their main axes, defined by the line connecting the N atoms of the nitro and amino groups, open an angle of 79.42 (3). Steric hindrance around the amino group is reflected in a long aryl C-N bond [1.434 (3) A for mol-ecule A and 1.440 (3) A for mol-ecule B], a pyramidal ge …

Multicategory angle-based large-margin classification.
Zhang C, Liu Y. Zhang C, et al. Biometrika. 2014 Sep;101(3):625-640. doi: 10.1093/biomet/asu017. Epub 2014 Jul 23. Biometrika. 2014. PMID: 26538663 Free PMC article.
Among existing simultaneous multicategory large-margin classifiers, a common approach is to learn k different functions for a k-class problem with a sum-to-zero constraint. Such a formulation can be inefficient. We propose a new multicategory angle-based large-margi …
