A new method for data stream mining based on the misclassification error.

IEEE transactions on neural networks and learning systems

Rutkowski L, Jaworski M, Pietruczuk L, Duda P.
PMID: 25051560
IEEE Trans Neural Netw Learn Syst. 2015 May;26(5):1048-59. doi: 10.1109/TNNLS.2014.2333557. Epub 2014 Jul 16.

In this paper, a new method for constructing decision trees for stream data is proposed. First a new splitting criterion based on the misclassification error is derived. A theorem is proven showing that the best attribute computed in considered...

Defects in cytochrome c oxidase expression induce a metabolic shift to glycolysis and carcinogenesis.

Genomics data

Dong DW, Srinivasan S, Guha M, Avadhani NG.

Genom Data. 2015 Aug 14;6:99-107. doi: 10.1016/j.gdata.2015.07.031. eCollection 2015 Dec.

Mitochondrial metabolic dysfunction is often seen in cancers. This paper shows that the defect in a mitochondrial electron transport component, the cytochrome c oxidase (CcO), leads to increased glycolysis and carcinogenesis. Using whole genome microarray expression analysis we show...

Temperature and pulse-duration dependence of second-harmonic generation in CdGeAs2.

Applied optics

Zakel A, Blackshire JL, Schunemann PG, Setzler SD, Goldstein J, Guha S.
PMID: 12003223
Appl Opt. 2002 Apr 20;41(12):2299-303. doi: 10.1364/ao.41.002299.

A detailed investigation of frequency doubling of a transversely excited atmospheric CO2 laser operating at 9.55 microm with a CdGeAs2 crystal was carried out. The temperature of the crystal was varied between 80 and 295 K to maximize the...

Phys Rev Lett. 2004 Sep 03;93(10):107207. doi: 10.1103/PhysRevLett.93.107207. Epub 2004 Sep 03.

We have investigated the detailed magnetic field dependence of the electric polarization and dielectric constant in (Tb,Dy,Ho)Mn2O5 where magnetic and ferroelectric transitions are intimately coupled. Our fundamental discovery is the unprecedented large change of the dielectric constant with magnetic...
