Traditionally, feature selection methods work directly on labeled examples. However, the availability of labeled examples cannot be taken for granted for many real world applications, such as medical diagnosis, forensic science, fraud detection, etc, where labeled examples are hard to find. This practical problem calls the need for “semi-supervised feature selection” to choose the optimal set o...

We consider the task of learning a classifier from the feature space X to the set of classes Y = {0, 1}, when the features can be partitioned into class-conditionally independent feature sets X 1 and X 2. We show the surprising fact that the class-conditional independence can be used to represent the original learning task in terms of 1) learning a classifier from X 2 to X 1 and 2) learning the...

manipulation of stress related transcription factors to improve plant stress tolerance is a major goal of current biotechnology researches. myc2 gene encodes a key stress-related transcription factor involved in jasmonate (ja) and abscisic acid (aba) signaling pathways in arabidopsis. brassica napus, as a globally important oilseed crop, is a close relative of arabidopsis.  in the present study...

1. We show cycle detection results using the proposed unsupervised constraint mining approach on the large-scale ImageNet 2012 dataset as well as three image datasets with generic objects (CIFAR-10), fine-grained objects (CUB200-2011), and scene classes (MIT indoor-67), respectively. 2. We show examples of easy negative image pairs (i.e., image pairs with large Euclidean distance in the feature...

OBJECTIVE To evaluate three prototype versions of semi-quantitative end-tidal CO2 monitors with different alarm features during prehospital or interfacility use. METHODS Subjects were 43 adult, non-pregnant patients requiring intubation, or who already were intubated and required transport. Teams at one AirEvac and seven Advanced Life Support (ALS) paramedic stations were trained in the use o...

BACKGROUND Semi-quantitative Gram stain and culture methods are still commonly used for diagnosing ventilator-associated pneumonia (VAP), due to its convenience. Only a few studies, however, have assessed the reliability of these methods when compared with quantitative cultures, a current standard for the diagnosis of VAP. The objective of this study was to assess the utility of semi-quantitati...
