The true-fake detection of Chinese liquors can be considered as a one-class classification problem. Using only positive sample in training process brings about difficulties in determining the optimal parameters of one-class SVM and its kernel. And one-class SVM optimized with conventional grid search method has a low recognition rate of positive test samples. Hence, we proposed a new idea for recognition,...
A multi-robot based mass flux divergence algorithm for odor source declaration in 3-dimensional flow fields is proposed. In this algorithm, four robots form a regular tetrahedron, computing the divergence value at tetrahedral center through gas concentration and fluid velocity sampled at the four vertices. Taylor-series expansion is given to calculate the mass flux divergence in the case of unknown...
