A novel RRAM-based pattern recognition system with locally inhibited post-neurons is developed. The system is able to learn the whole MNIST training set (60,000 patterns). By using the system, the same post-neuron is fired by the similar patterns in the same training class, which causes the reduction of hardware cost. With the locally inhibited post-neuron, the system can achieve more than 90.73%...
This paper proposes a GA-SVM classification method which is applied to the dynamic evaluation of taekwondo. For classifying a dynamic action, we converted a dynamic action signal to a frequency spectrum signal for analysis. However, the useful features were concentrated in a part of the frequency spectrum, and the useless features led to a decline in accuracy, operation speed, and efficiency of the...
An analog neuromorphic system is developed based on the fabricated resistive switching memory array. A novel training scheme is proposed to optimize the performance of the analog system by utilizing the segmented synaptic behavior. The scheme is demonstrated on a grayscale image recognition. According to the experiment results, the optimized one improves learning accuracy from 77.83% to 91.32%, decreases...
A method is introduced in this paper for monitoring the transmission quality of streaming media. The transmission quality of streaming media is characterized by some parameters, such as transmission bandwidth, jitter and packet loss rate, etc. A model is given to illustrate how to obtain these parameters. Then, a monitoring system based on this model is implemented on the Windows XP SP2 platform....
