This paper presents a research method to directly recognize greeting voice without segmentation to avoid error recognition because of error segmentation. The basic principle of biomimetic pattern recognition is applied to speaker-independent and continuous speech recognition of greeting. The high-dimension space covering theory is applied to the learning(More)
AIM To test changes in the phylogenetic relatedness, niche breadth, and life-history strategies of nematodes along a latitudinal gradient. LOCATION Sixteen wetland locations along the Pacific coast of China, from 20°N to 40°N. METHODS Linear regression was used to relate nematode phylogenetic relatedness (average taxonomic distinctness (AvTD) and(More)
Objective: To research on the application of high dimensional space theory to the biomimetic pattern recognition. Procedures: The sample was constructed into a k-dimensional simplex in a high dimensional space and 0.85 times of the average distance between the vertices was chosen as the threshold value thus a convex cell body covering the k-dimensional(More)
