Methods of security situation prediction for industrial internet fused attention mechanism and BSRU
Published 2022-02-01“…The security situation prediction plays an important role in balanced and reliable work for industrial internet.In the face of massive, high-dimensional and time-series data generated in the industrial production process, traditional prediction models are difficult to accurately and efficiently predict the network security situation.Therefore, the methods of security situation prediction for industrial internet fused attention mechanism and bi-directional simple recurrent unit (BSRU) were proposed to meet the real-time and accuracy requirements of industrial production.Each security element was analyzed and processed, so that it could reflect the current network state and facilitate the calculation of the situation value.One-dimensional convolutional network was used to extract the spatial dimension features between each security element and preserve the temporal correlation between features.The BSRU network was used to extract the time dimension features between the data information and reduced the loss of historical information.Meanwhile, with the powerful parallel capability of SRU network, the training time of model was reduced.Attention mechanism was introduced to optimize the correlation weight of BSRU hidden state to highlight strong correlation factors, reduced the influence of weak correlation factors, and realized the prediction of industrial internet security situation combining attention mechanism and BSRU.The comparative experimental results show that the model reduces the training time and training error by 13.1% and 28.5% than the model using bidirectional long short-term memory network and bidirectional gated recurrent unit.Compared with the convolutional and BSRU network fusion model without attention mechanism, the prediction error is reduced by 28.8% despite the training time increased by 2%.The prediction effect under different prediction time is better than other models.Compared with other prediction network models, this model achieves the optimization of time performance and uses the attention mechanism to improve the prediction accuracy of the model under the premise of increasing a small amount of time cost.The proposed model can well fit the trend of network security situation, meanwhile, it has some advantages in multistep prediction.…”

Temporal and Spatial Evolution Characteristics of Extreme Climate Events in Grand Shangri-La Region from 1961 to 2019
Published 2022-01-01“…The Grand Shangri-La region connects the Qinghai-Tibet Plateau,the Yunnan-Guizhou Plateau,and the Hengduan Mountains and is of great geographical significance.Five rivers flow through the region,and the climate is vulnerable.Therefore,it is necessary to explore extreme climate changes and their response mechanism,so as to assess regional climate risks and achieve disaster warnings.Based on the daily temperature and precipitation data of 56 meteorological stations from 1961 to 2019,this paper analyzes changes in extreme climate indexes and their correlation with large-scale circulation index in the region by using Mann-Kendall,Sen's slope estimation,Pettitt test,and Pearson correlation analysis.The results show that:① The extreme warm index and the extreme precipitation intensity index (RX1day,R95p,R99p,and SDII) increase significantly,while the cold index (CSDI、FD、ID、TN10p、TX10p) and the number of continuous humid days decrease greatly.In terms of different seasons,the warming amplitude of most of the extreme temperature indexes in winter is higher than that in summer,and the precipitation intensity increases gradually in summer and autumn but decreases slightly in winter.② Spatially,the diurnal temperature range in the north of the Qinghai-Tibet Plateau is higher than that in the south,and the frequency of extremely high-temperature rises,with the high temperature appearing mostly in arid valleys in the south and east of the Qinghai-Tibet Plateau.The precipitation intensity is high in the south and west of the Hengduan Mountains,and persistent precipitation is strong in the Yalong River basin and the upper reaches of the Jinsha River in the north.③ Extreme climate indexes and south China sea summer monsoon index (SCSMI) are significantly correlated in the same year.In addition,there is a one-year response lag between the extreme precipitation index and Arctic oscillation (AO),North Atlantic oscillation (NAO),and Pacific decadal oscillation (PDO).The above analysis shows that the Grand Shangri-La region generally shows warming and humid climate characteristics.The frequency of heavy precipitation in flood season and warm winter events increases and is closely related to large-scale circulation.…”
