Cuban efforts bolstered
bird flu but were not diagnosed because their symptoms were too mild. The findings suggest some populations have developed natural resistance to the virus. The study of more than 45,000 people in Vietnam, reveals that up to 750 people are likely to have become infected with the strain after handling sick birds. Anna Thorson, who led the study, said the real figure potentially extended into thou...
متن کاملHigh-dimensional bolstered error estimation
MOTIVATION In small-sample settings, bolstered error estimation has been shown to perform better than cross-validation and competitively with bootstrap with regard to various criteria. The key issue for bolstering performance is the variance setting for the bolstering kernel. Heretofore, this variance has been determined in a non-parametric manner from the data. Although bolstering based on thi...
متن کاملBolstered error estimation
We propose a general method for error estimation that displays low variance and generally low bias as well. This method is based on “bolstering” the original empirical distribution of the data. It has a direct geometric interpretation and can be easily applied to any classification rule and any number of classes. This method can be used to improve the performance of any error-counting estimatio...
متن کاملOccupational Health: Agriculture–COPD Link Bolstered
Smoking is typically considered the cause of 80–90% of chronic obstructive pulmonary disease (COPD) cases, but another significant known source is occupational exposure. Among the suspect occupations is farming, for which there has long been limited evidence of a risk for various respiratory diseases , including COPD. That link has been bolstered by an Austrian study, based on clinical evidence...
متن کاملLanguage Independent Probabilistic Context-Free Parsing Bolstered by Machine Learning
Unlexicalized probabilistic context-free parsing is a general and flexible approach that sometimes reaches competitive results in multilingual dependency parsing even if a minimum of language-specific information is supplied. Furthermore, integrating parser results (good at long dependencies) and tagger results (good at short range dependencies, and more easily adaptable to treebank peculiariti...
