Born Again Trees
Tree predictors such as CART or C4.5 are often not as accurate as neural nets or use of multiple trees. But these latter methods lead to predictors whose structure is difficult to understand, whereas trees have a universal simplicity. Because of this, it is appealing to try and find tree representations of more complex predictors. We study tree representers of multiple tree predictors. These re...
متن کاملBorn Again Neural Networks
Knowledge distillation techniques seek to transfer knowledge acquired by a learned teacher model to a new student model. In prior work, the teacher typically is a high-capacity model with formidable performance, while the student is more compact. By transferring knowledge, one hopes to benefit from the student’s compactness while suffering only minimal degradation in performance. In this paper,...
متن کاملBorn-again Protoplanetary Disk around Mira B
TheMiraAB system is a nearby ( 107 pc) example of awind accreting binary star system. In this class of system, the wind from amass-losing red giant star (Mira A) is accreted onto a companion (Mira B), as indicated by an accretion shock signature in spectra at ultraviolet and X-ray wavelengths. Using novel imaging techniques, we report the detection of emission at mid-infrared wavelengths betwee...
متن کاملBorn-Again Cataloging in the Online Networks
Participation in an online network means that the work of individual libraries and their catalogers becomes visible to, and utilized by, many other libraries. Network affiliated libraries and network quality control personnel thus become participants in evaluating each cataloger's work. Results of a 1983-84 case study of six academic libraries indicate that the shift from inhouse to nationwide ...
متن کاملModelling the extinction of Steller's sea cow.
Steller's sea cow, a giant sirenian discovered in 1741 and extinct by 1768, is one of the few megafaunal mammal species to have died out during the historical period. The species is traditionally considered to have been exterminated by 'blitzkrieg'-style direct overharvesting for food, but it has also been proposed that its extinction resulted from a sea urchin population explosion triggered by...
