ASSPAE is a novel deep learning model, which is designed based on the stacked supervised Poisson autoencoders and attention-based multi-feature fusion strategy. Stacked supervised Poisson autoencoders are a novel deep neural networks model, which is designed by integrating the Poisson regression network layer into the deep autoencoders framework. Compared with the conventional autoencoder-based models, the proposed stacked supervised Poisson autoencoders not only can capture the quality-relevant deep features of the data, but also is suitable for predicting the count-type quality variable. Furthermore, in order to efficiently leverage information present in different layers of the network, an attention-based multi-feature fusion strategy is integrated into the stacked supervised Poisson autoencoders modeling framework. The effectiveness of the proposed ASSPAE method is evaluated by its application to the cast-rolling process of a steelmaking plant. The application results show that the prediction accuracy of the proposed ASSPAE modeling method was improved by 32%, 31%, 24%, and 13% in Root Mean Square Error (RMSE) compared with the partial least square regression, support vector regression, Poisson regression, and stacked autoencoders-Poisson regression, respectively.","PeriodicalId":412672,"journal":{"name":"2022 IEEE 11th Data Driven Control and Learning Systems Conference (DDCLS)","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-08-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116338377","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

By identifying the color difference of the reflective clothing, the network is capable of distinguish whether the target work type can enter relevant construction areas with different danger levels. In this paper, by constructing the labeled data set and training on the basis of YOLOv5 model framework, a target model is obtained. Its detection speed can adapt to real-time monitoring.

To solve this problem, a new type of actuator must be developed and reluctance actuator has been proposed as one of the most potential candidates. However, the strong nonlinearity of the reluctance motor limits its application in ultra-precision. For example, the hysteresis effect, the relationship between force and current, and force and displacement, and so on. In this paper, a combined control strategy composed of feedforward compensation and PID is introduced to the reluctance actuator system, and the BP neural network and stochastic configuration network (SCN) are applied to the construction of the hysteresis inverse model. According to the simulation results, it can be concluded that the accuracy of the inverse model constructed by the SCN method is higher than that of the inverse model constructed by the BP neural network. It is concluded that the Stochastic Configuration Network method is effective for the hysteresis nonlinearity compensation of the reluctance actuators, and promising in precision stage control.","PeriodicalId":412672,"journal":{"name":"2022 IEEE 11th Data Driven Control and Learning Systems Conference (DDCLS)","volume":"128 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-08-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131367320","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

And human motion is essentially a multimodal motion, which brings great challenges to the trajectory prediction. Meanwhile, most sequence-to-sequence models only consider one of the temporal and spatial characteristics of pedestrian motion and ignore other. Therefore, based on the temporal and spatial attention mechanism and the transformer model, we fuse the temporal and spatial characteristics of the imputation, and propose a deep learning prediction model based on the spatial-temporal attention transformer mechanism (STATM). Our model designs a temporal attention module based on multi-head attention, a spatial attention module based on GAT, and finally maps spatial-temporal features to trajectory destinations through a transformer-decoder-like module.

By using the algorithm, it can be guaranteed that, within a finite temporal interval, the containment errors between the followers' states and the convex hull that leaders' states forms are bounded. And furthermore, if there are no initial errors, state containment errors will approach zero when there are enough iterations.

Combining the model-based condition with a recent data-based system representation, a data-driven stability criterion in the form of linear matrix inequalities (LMIs) is established, which offers a way of co-designing the ETS matrix and the controller using pre-collected noisy input-state data.
