Wanyi Gu,Guojun Wang,Peiqiang Li,Xubin Li,Guangxin Zhai,Xiangbin Li,Mingfei Chentrong-coupling problem. Namely it is the QED theory, where the correspondent problem of the “Landau pole” or the “Moscow zero” of the beta-function have led to the well known discussion about the common base of the quantum field theory.

Detecting Unknown Vulnerabilities in Smart Contracts with Multi-Label Classification Model Using CNNiLSTM model. Our model determines whether a vulnerability is unknown by detecting the opcode sequence representing the entire execution process of a transaction. Experimental results with the opcode sequences of transactions show that the model can achieve 82.86% accuracy and 83.63% F1-score.

Detecting Unknown Vulnerabilities in Smart Contracts with Binary Classification Model Using Machine inally, we validate the effectiveness of our scheme by three machine learning models, namely the K-Near Neighbor Algorithm (KNN), the Support Vector Machine (SVM), and the Logistic Regression (LR). The SVM model achieves an accuracy of 91.4% and F1-score of 75.3% for the detection of unknown vulnerabilities.

Hierarchical Policies of Subgoals for Safe Deep Reinforcement Learningper, we combine the subgoal embedding method with REINFORCE algorithm and PPO(Proximal Policy Optimization) algorithm to test the method in the MiniGrid-DoorKey game environment of the gym platform. The experiments demonstrate the effectiveness of the subgoal embedding method.
