针对靶场试验中利用初速雷达测试弹丸初速需要重构的情况
选择同时参试的两台雷达的数据进行融合建立神经网络模型
用一台雷达的数据预测出另一台雷达需要重构的数据。由于预测模型预测精度的高低取决于所建模型的好坏
而模型的好坏取决于样本数据的质量
先利用聚类分析和关联规则从大量历史试验数据中挖掘出优质的样本
再建立神经网络进行预测。实验结果表明
与支持向量回归机相比
由聚类分析关联规则神经网络构建的组合算法的预测精度更高
预测历史相似数据误差远小于1‰
预测与历史出入较大的数据的精度也较为理想。两种情况下的预测结果表明
组合算法既保证了预测精度又具有一定的鲁棒性
可以作为弹丸初速的预测模型。
In view of the situation that reconstruction is needed for the muzzle velocity of a projectile measured by muzzle velocity radar in the range test
the data of two radars used in the test at the same time are fused to establish a neural network model
and the data of one radar is used to predict the data that needs to be reconstructed by the other radar. Because the prediction accuracy of the prediction model depends on the quality of the model
and the model quality depends on the quality of the sample data
we first use cluster analysis and association rules to mine high-quality samples from a large number of historical test data
and then establish a neural network for prediction. The experimental results show that: compared with support vector regression machine
the prediction accuracy of the combined algorithm constructed by clustering analysis association rules and neural network is higher
the error of predicting similar historical data is far less than 1‰
and the accuracy of predicting data significantly different from historical data is also more reasonable. The prediction results in the two cases show that the combined algorithm not only ensures the prediction accuracy
but also has certain robustness
and can be used as the prediction model of projectile muzzle velocity.

DOI: 10.11896/jsjkx.190300150 http://doi.org/10.11896/jsjkx.190300150 传统单标签挖掘技术研究中,每个样本只属于一个标签且标签之间两两互斥。而在多标签学习问题中,一个样本可能对应多个标签,并且各标签之间往往具有关联性。目前,标签间关联性研究逐渐成为多标签学习研究的热门问题。首先为适应大数据环境,对传统关联规则挖掘算法Apriori进行并行化改进,提出基于Hadoop的并行化算法Apriori_ING,实现各节点独立完成候选项集的生成、剪枝与支持数统计,充分发挥并行化的优势;通过Apriori_ING算法得到的频繁项集和关联规则生成标签集合,提出基于推理机的标签集合生成算法IETG。然后,将标签集合应用到多标签学习中,提出多标签学习算法FreLP。FreLP利用关联规则生成标签集合,将原始标签集分解为多个子集,再使用LP算法训练分类器。通过实验将FreLP与现有的多标签学习算法进行对比,结果表明在不同评价指标下所提算法可以取得更好的结果。

The different UAV missions may have different quality of service (QoS) requirements due to the uncertainty of UAV missions and the fast-changing battlefield environment. A BP neuron network-based feedback differentiated control approach for QoS-aware (BPFD)-MAC in UAV cloud is proposed, which can support both absolute and relative QoS guarantees with the consideration of energy saving. The hardware experiments demonstrate the feasibility of BPFD-MAC. Under heavy loads, BPFD has better throughput and power use efficiency; and under light load, BPFD has lower total energy consumption.Key
