This paper is concerned with secure consensus of second-order discrete-time multi-agent systems under replay attacks. State information is transmitted over a communication network and each agent may be attacked by an adversary who is able to replay the state information sent from its neighbors maliciously. A consensus protocol based on distributed model predictive control is developed in the presence of replay attacks. The sufficient conditions for multi-agent systems to achieve secure consensus under replay attacks is derived. The effectiveness of the consensus protocol based on distributed model predictive control is illustrated through numerical examples.

In order to characterize causal relation, different scholars have studied it from multiple perspectives. In the field of logic, the causal theory proposed by Alexander elaborated the causal relationship from the perspective of nonmonotonic reasoning. The Horn causal theory and the concept of equivalence relationship are defined in his article, but the author did not give the determination method of equivalence relationship. In order to make up for this deficiency, this paper introduces the concept of bisimulation to describe the equivalence relation between Horn causal theories and proves the consistency between bisimulation relation and the equivalence of models. Then the corresponding algorithm is proposed to determine the equivalence. An example is also given to illustrate the application of this method in determining equivalence relationship.

Timely identification of Chinese Microblogs users' stance and tendency is of great significance for social managers to understand the trends of online public opinion. Traditional stance detection methods underutilize target information, which affects the detection effect. This paper proposes to integrate the target subject information into a Chinese Microblogs stance detection method based on a generalized autoregressive pretraining language model, and use the advantages of the generalized autoregressive model to extract deep semantics to weaken the high randomness of Microblogs self-media text language and lack of grammar. The impact of norms on text modeling. First carry out microblog data preprocessing to reduce the influence of noise data on the detection effect; then connect the target subject information and the text sequence to be tested into the XLNet network for fine-tuning training; Finally, the fine-tuned XLNet network is combined with the Softmax regression model for stance classification. The experimental results show that the value of the proposed method in the NLPCC2016 Chinese Microblogs detection and evaluation task reaches 0.75, which is better than the existing public model, and the effect is improved significantly.

In this paper, an Intelligent Hierarchical Conditional Random Field based Attention Mechanism (HCRF-AM) model is proposed, which can be applied to the Gastric Histopathology Image Classification (GHIC) tasks to assist pathologists in medical diagnosis. However, there exists redundant information in a weakly supervised learning mission. Thus, designing the network that can extract effective distinguishing features has become the focus of research. The HCRF-AM model consists of attention mechanism (AM) module and image classification (IC) module. First, in the AM module, an HCRF model is built to extract attention areas. Then, a convolutional neural network (CNN) model is trained with the attention region selected. Thirdly, an algorithm called classification probability based Ensemble Learning (EL) is used to obtain the image-level result from patch-level output of the CNN. In the experiment, a classification specificity of 96.67% is achieved on a gastric histopathological dataset with 700 images.

Rapid development in deep learning is making it easier to create fake videos known as “deepfake” videos in which human faces are swapped. Since deepfake videos are difficult to recognize by human eyes, it becomes important to automatically detect these forgeries and prevent their abuse. In this paper, we propose a deep neural network model to detect deepfake videos using a convolutional neural network (CNN) to extract frame-level features. These features are then used to train a convolutional GRU that learns to distinguish between fake and real videos. Evaluation is performed on the recently released Celeb-DF(v2)datasets where a state-of-art AUC score was achieved.

In recent years, with the rapid development of the Internet, complex and diverse applications and network traffic have been generated. At the same time, network encryption technologies and various new network traffic have emerged, which affects the efficiency of the original traffic classification technology. In order to improve the efficiency of traffic classification and reduce the classification time, this paper proposes a network traffic classification model (Cosine similarity and decision tree classification model, CSDT) based on cosine similarity and decision tree algorithm to identify and classify traffic. First, the cosine similarity algorithm is used to judge the similarity of adjacent network traffic, and the network traffic with higher similarity is labeled with a known classification and forwarded. For network traffic with low similarity, the decision tree algorithm is used to classify the related feature values. This model utilizes the characteristics of high similarity in adjacent data streams, and uses similarity algorithms to preprocess network traffic to reduce classification time. The Moore data set publicly available in the field of network traffic classification is used for training and testing, and the results are compared with various machine learning algorithms on the Weka platform. The experimental results show that the model has a good classification accuracy, which greatly reduces the classification time and improves the classification efficiency of network traffic is improved.

We have known that reinforcement learning, deep learning, and deep reinforcement learning effectively acquire action rules for the autonomous motion of objects. However, it is known that these learning processes require a large amount of learning time. Besides, we should consider the similarity of the environment between the training target and the test target. In actual autonomous driving, there is no such thing as driving only on a course that has been learned in advance. In this study, the autonomous driving of a model car is used as the experimental object. The training target for acquiring the learning model and the actual driving courses are changed. In this study, we report on the effectiveness of transfer learning using a model car as the basis for a learning model acquired by reinforcement learning.

While there is an ever increasing collection of domain-specific news, it is difficult for people to identify the important ones from massive information. The challenge lies in that users’ information, e.g., comments and CTR (Click-Through-Rate), may not be available in those professional news articles. In this paper, we develop a deep learning model for important news push service, referred to as HMA, which consists of a Hierarchical attention network and a Multi-head Attention mechanism for non-linear text regression. We conduct the experiments with a dataset of marine industry news to evaluate the performance of the proposed deep learning model. The experiment results show that HMA outperforms other alternative deep learning models due to the hierarchical structure and multi-head attention mechanism. Moreover, the execution time of inference by HMA is less than the computation of TF-IDF when adding the news articles into the news repository. Therefore, the proposed method has the potential for efficiently pushing the important domain-specific news articles without users’ information.
