The state-owned forests in Heilongjiang province made significant contribution to China's economic development, but with a huge price of serious ecological deterioration. So modern forestry construction of the state-owned forest focuses on strengthening the modern forestry ecological system. The key is the selection of key areas of ecological system. This paper takes Yichun state-owned forest for...
Selective ensemble learning is a learning algorithm, trains a number of based classifier and selects some of them to ensemble. Through the selective ensemble, the algorithm would be more effective than each single one and better than the algorithm that select all the based classifier, and the algorithm would have effective generalization ability. In this paper, we apply a multi-lever selective ensemble...
The construction of modern forestry is the general task to China's forestry work. It is a system engineering involving China's forestry ecological, economic, social and cultural development as well as institutional mechanisms reforming and so on. It is an important means of accelerating the pace of modern forestry through establishing scientific and rational, highly operative modern forestry statistical...
Extracting invariable features is one key issue for 3D model searching. A novel invariable feature extraction method, namely geometry projection based histogram model, is proposed for 3D model description. Different from the traditional method, one projection plane (or surface) is created for each 3D model, and the points of 3D models are projected to the projection plane (or surface), and then the...
