In Defense of One-Vs-All Classification
We consider the problem of multiclass classification. Our main thesis is that a simple “one-vs-all” scheme is as accurate as any other approach, assuming that the underlying binary classifiers are well-tuned regularized classifiers such as support vector machines. This thesis is interesting in that it disagrees with a large body of recent published work on multiclass classification. We support ...
متن کاملA Prokaryotic Twist on Argonaute Function
Argonaute proteins can be found in all three domains of life. In eukaryotic organisms, Argonaute is, as the functional core of the RNA-silencing machinery, critically involved in the regulation of gene expression. Despite the mechanistic and structural similarities between archaeal, bacterial and eukaryotic Argonaute proteins, the biological function of bacterial and archaeal Argonautes has rem...
متن کاملTranscript analysis of some defense genes of tomato in response to host and non-host bacterial pathogens
The transcript levels of six defense genes including pathogenesis-related gene 1 (PR-1), pathogenesis-related gene 2 (PR-2), pathogenesis-related gene 5 (PR-5), lipoxygenase (LOX), phenylalanine ammonia-lyase (PAL) and catalase (CAT) were investigated in tomato plants inoculated with Xanthomonas axonopodis pv. phaseoli as a non-host pathogen and X. euvesicatoria as a host pathogen. Activation o...
متن کاملContribution of the Argonaute-1 Isoforms to Invertebrate Antiviral Defense
Argonaute (Ago) protein, the central component of the RNA interference (RNAi) pathway, plays important roles in host innate antiviral immunity. Most organisms harbor a large number of different Ago proteins and isoforms; however, the roles of Ago isoforms in immune defense against pathogens remain unclear. In the present study, three Argonaute-1 (Ago1) isoforms, termed Ago1A, Ago1B, and Ago1C, ...
متن کاملHost Defense against Bacterial Endotoxemia: Mechanism in Normal Animals
The present study defines the early response of normal rabbits to the intravenous injection of a single, sublethal dose of endotoxin. Within the first few hours following endotoxin there occurs in the circulating plasma of recipients a decrease in ionized calcium, a threefold increase in the heat-stable, organo-phosphate-resistant esterase level, and a striking increase in the endotoxin-detoxif...
