The technology of lower limb rehabilitation robot is a hot research topic in recent years, while the exoskeleton robot is a typical representative. Accurate trajectory tracking ability is the base of the exoskeleton mechanical leg to coordinately drive trainers to do rehabilitation training on the treadmill. In this paper, aiming at the existing exoskeleton body, taking into account the uncertain...
Recently, consumer depth cameras have gained significant popularity due to their affordable cost. However, the limited resolution and the quality of the depth map generated by these cameras are still problematic for several applications. In this paper, a novel framework for the single depth image superresolution is proposed. In our framework, the upscaling of a single depth image is guided by a high-resolution...
In this paper, a new abnormal activity detection algorithm is proposed for multi-camera surveillance applications. The proposed algorithm models the entire scene covered by the multi-camera system as a network. In this network, each node corresponds to a segmentation of the entire scene and each edge represents the activity correlation between the corresponding segmentations. Based on this network,...
Personal Credit Scoring is of great significance for commercial banks to circumvent credit consumption, the original BP algorithm's convergence rate is slow, learning precision is low, the training process is easy to fall into local minimum, this paper presents an improved algorithm with variable learning rate based on BP algorithm, and applied to simulate personal credit scoring. After comparing...
Piezoresistive micro-mechanical acceleration sensor is one of the earliest developed silicon micro-mechanical acceleration sensors in MEMS. Its cantilever beam is the main component. So the structure optimization design of the cantilever beam becomes the key. During the process of the former structure optimization of the cantilever beam, the working way between the program of FEM analysis and the...
Based on analyzing fundamental algorithms principle of back propagation network, in view of the limitations of BP network algorithm, this paper proposed the homologous improved algorithms from two respects: accelerate the learning speed of BP network and advance the convergence degree of network. By means of increasing the discrepancy factors of neuron function, the traditional function is optimized...
Based on analyzing fundamental principle of back propagation network model, the paper has established a topology network structure include 12 input layer 25 hidden layer and 2 output layer, 12 input nodes correspond the heighten expression of well performance time cell, 2 output nodes correspond the crude output and water production. According to the tracking model of BP network, this paper takes...
