Heartbeat classification and R-wave location have been widely used to detect people's health condition. And battery-power devices are mainly applied to wearable scenario, which can monitor people's health all day long, so high energy efficiency is very important under such circumstance. This paper proposes an improved DWT (Discrete Wavelet Transform) algorithm to obtain time-frequency characteristics...
In this paper, a new condition-based maintenance method of game for the aircraft fleet is proposed. In hope of successfully deploying the aircraft fleet, some game rules are set, which prompts the generation of maintenance strategy. And the problem is transformed into a multi-phased combinatorial optimization problem. Then an algorithm of multi-stage sequential game that based on state backtracking...
In order to improve the accuracy and efficiency of directly use of the k-means clustering for semi-supervised learning, the paper proposes a new semi-supervised learning algorithm based on radius-distance. In the algorithm, according to radius, farthest distance of sample to the cluster center of unlabelled samples using k-means, and distance, from cluster center of unlabelled samples to center of...
