【摘要】：針對(duì)現(xiàn)有報(bào)警選擇方法在實(shí)時(shí)性和精確性方面存在的不足,提出一種基于有向滑動(dòng)時(shí)間窗的報(bào)警動(dòng)態(tài)選擇算法。依據(jù)歷史關(guān)聯(lián)結(jié)果的趨向特征,動(dòng)態(tài)調(diào)整每個(gè)時(shí)間窗內(nèi)報(bào)警抽取的概率,向歷史關(guān)聯(lián)強(qiáng)度高的時(shí)間窗分配更高的抽取概率,提高報(bào)警關(guān)聯(lián)的效率和準(zhǔn)確性。仿真結(jié)果表明,該算法在實(shí)時(shí)性上遠(yuǎn)高于報(bào)警全選方法和隨機(jī)選擇方法,在關(guān)聯(lián)精度上優(yōu)于隨機(jī)選擇方法。
[Abstract]:In view of the shortcomings of the existing alarm selection methods in real-time and accuracy, a dynamic alarm selection algorithm based on directional sliding time window is proposed, which is based on the trend characteristics of historical correlation results. Dynamically adjust the probability of alarm extraction in each time window, assign a higher extraction probability to the time window with high historical correlation intensity, and improve the efficiency and accuracy of alarm correlation. The simulation results show that, The algorithm is much better in real time than the full alarm selection method and random selection method, and the correlation accuracy is better than the random selection method.
