Association between an individual dietary index based on the British Food Standard Agency Nutrient Profiling System and asthma symptoms

, 2019
The role of diet in asthma is still debated. In France, a front-of-pack (FOP) nutrition label based on a modified Food Standards Agency Nutrient Profiling System/High Council for Public Health (FSAm-NPS/HCSP) has recently been implemented to help ...

Spatial Prior Fuzziness Pool-Based Interactive Classification of Hyperspectral Images

Remote Sensing, 2019
Acquisition of labeled data for supervised Hyperspectral Image (HSI) classification is expensive in terms of both time and costs. Moreover, manual selection and labeling are often subjective and tend to induce redundancy into the classifier.
