Multi-instance learning, as other machine learning tasks, also suffers from the curse of dimensionality. Although dimensionality reduction methods have been investigated for many years, multi-instance dimensionality reduction methods remain untouched. On the other hand, most algorithms in multi-instance framework treat instances in each bag as independently and identically distributed (i.i.d.) ...

conclusions surgical wound infections are less common by using reusable retrieval bag during laparoscopic appendectomy procedure. also, using reusable retrieval bag has less cost. patients and methods one hundred twenty laparoscopic appendectomies performed over one year, were included in this retrospective study. the patients were divided into 2 group; group a was the one in which la was done ...

an air filter is a significant element of any mechanical ventilation system. however, the importance and performance evaluation of air filters have not been well publicized and related scientific reports are scarce. in this study, a transportable, off-line, air filter-testing unit (the unit) was designed and utilized to simulate the filter housing of a mechanical ventilation system. the unit wa...
