Out of the bag

The NAAT is out of the bag.

Aneurysm prevention: keep the cat out of the bag.

In this issue of Cardiovascular Research, Qin et al. show that the incidence of abdominal aortic aneurysm formation in apolipoprotein E (apo E) knockout mice is profoundly inhibited if the mice are additionally deficient in cathepsin S, an elastinolytic cysteine proteinase. Cathepsin S, traditionally thought of as a lysosomal proteinase involved only in the terminal degradation of endocytosed p...

On the overestimation of random forest’s out-of-bag error

Background The ensemble method random forests has become a popular classification tool in bioinformatics and related fields. The out-of-bag error is an error estimation technique which is often used to evaluate the accuracy of a random forest as well as for selecting appropriate values for tuning parameters, such as the number of candidate predictors that are randomly drawn for a split, referre...

Getting the best out of a mixed bag

This paper discusses the development and implementation of an approach to the combination of Rule Based Machine Translation, Statistical Machine Translation and Translation Memory tecnologies. The machine translation system itself draws upon translation memories and both syntactically and statistically generated phrase tables, unresolved sentences being fed to a Rules Engine. The output of the ...

Letting Keys and Functional Dependencies out of the Bag

Classical database theory is largely a theory of relations. Relations are sets of tuples in which no duplicate tuples occur. In practice, duplicate elimination is an operation that is considered to be too expensive in many situations. Fundamental classes of integrity constraints interact differently over bags than they do over relations. This holds for keys and functional dependencies, for exam...
