If it worked last time, it should work again: justifying and validating case-based plans

Throughout artificial intelligence, more attention is being given to validation and evaluation of programs. This is especially an issue in case-based reasoning, since the domains for which CBR is best suited are those with a weak domain theory, such as law, medical diagnosis, cooking, and military strategy. In such domains, validation must take on a different meaning. We cannot "prove" that the...

Resilient Face Expressional Recognitions Using Geometry and Behavioral Characteristics

Tremendous growth in the use of biometric technologies in high-security applications has motivated the requirement for highly dependable face recognition systems with expressional robustness. Current standards demonstrated that the accuracy of state-of-the-art algorithms is fairly high under constrained conditions, but degrades significantly for images exhibiting facial expression variations. T...

Polyvalent carbocyanine molecular beacons for molecular recognitions.

Polyvalent carboxylate-terminating near-infrared (NIR) carbocyanine molecular beacons were prepared by homologation of reactive carboxyl groups of the beacon with imino diacetic acid. Their conjugation with unprotected d-(+)-glucosamine gave dendritic arrays of the carbohydrate on an inner NIR chromophore core. In vivo evaluation of the dendritic glucosamine constructs shows enhanced uptake in ...

Competition Among Medicare's Private Health Plans: Does It Really Exist?

Competition among private Medicare Advantage (MA) plans is seen by some as leading to lower premiums and expanded benefits. But how much competition exists in MA markets? Using a standard measure of market competition, our analysis finds that 97 percent of markets in U.S. counties are highly concentrated and therefore lacking in significant MA plan competition. Competition is considerably lower...
