Boosted Decision Trees as an Alternative to Artificial Neural Networks for Particle Identification
The efficacy of particle identification is compared using artificial neutral
networks and boosted decision trees. The comparison is performed in the context
of the MiniBooNE, an experiment at Fermilab searching for neutrino
oscillations. Based on studies of Monte Carlo samples of simulated data,
particle identification with boosting algorithms has better performance than
that with artificial neural networks for the MiniBooNE experiment. Although the
tests in this paper were for one experiment, it is expected that boosting
algorithms will find wide application in physics.Comment: 6 pages, 5 figures; Accepted for publication in Nucl. Inst. & Meth.
2-[(4-BromoÂphenylÂimino)ÂmethÂyl]-4,6-diÂiodoÂphenol
The title compound, C13H8BrI2NO, was prepared by the reaction of 3,5-diiodoÂsalicylÂaldehyde with 4-bromoÂphenylÂamine in ethanol. There is an intraÂmolecular O—H⋯N hydrogen bond in the molÂecule, which generates an S(6) ring. The dihedral angle between the benzene rings is 2.6 (3)°
2-[(2-ChloroÂphenÂyl)iminoÂmethÂyl]-4,6-diÂiodoÂphenol
The asymmetric unit of the title compound, C13H8ClI2NO, contains half of the molÂecule situated on a mirror plane. The hyÂdroxy group is involved in the formation of an intraÂmolecular O—H⋯N hydrogen bond. π–π interÂactions between the benzene rings of neighbouring molÂecules [centroid–centroid distance = 3.629 (3) Å] form stacks along the b axis. In the crystal, weak C—H⋯O and C—H⋯Cl interÂactions are observed
