For the problem of parameter learning in pattern recognition, when there is a pos~ibility of training samples being mislabeled, the authors have investigated the convergence of stochastic-approximation-based learning algorithms. ln the caSeS considered. il is found that estimates converge 10 nonlrue values in the presence of labeling errors. The general ",-class, N-kature pallern recognition pr...

The real-world applications to massive data processing raise two huge challenges to the traditional supervised machine learning. First, the sufficient training examples to ensure the generalization ability become unavailable, since the task of labeling examples by experts is time-consuming and expensive; second, it is impossible to load massive data into memory, and the response time is unaccep...

Authentic samples of commercially produced organic and conventionally grown tomatoes, lettuces, and carrots were collected and analyzed for their delta15N composition in order to assemble datasets to establish if there are any systematic differences in nitrogen isotope composition due to the method of production. The tomato and lettuce datasets suggest that the different types of fertilizer com...
