In this way, polynomial kernel SVM is often better than linear kernel which did not use feature conjunctions. However, the training and testing time...

However, engineering an allosteric DNAzyme with dual RNA-cleaving and DNA-cleaving activities is very challenging. ... site, where the DNA-cleaving active site of DRc DNAzyme is hindered through the binding of RS. The self-cleaving DRc DNAzyme was incubated in reaction buffer B, containing 100 lm CuCl 2 , 0.3...

Rerank- ing and SEPA are thus relatively independent. Bagging (Breiman, 1996) uses an ensemble of in- stances of a model, each trained on a sample of the training data 1 . Bagging was sugg...
