题目:Distributed Robust Nash Equilibrium Seeking for Games with Partial Decision Information

摘要: Game theory has been widely adopted to deal with interactive decision-making problems in various distributed systems such as smart grids, wireless communication networks, traffic systems, etc. As a result, distributed Nash equilibrium seeking strategies have recently attracted increasing attention due to their remarkable advantages in relaxing the requirement of a central node for information broadcasting or full observation over players’ actions. This talk aims to provide a glimpse of recent advances on distributed Nash equilibrium seeking in games with partial decision information. In particular, some robust strategies will be discussed in details. Finally, some promising directions are suggested for future research.

题目:Learning-based Sampling Strategies for Robot Path Planning

摘要:Sampling-based path planning algorithms have become very popular due to their capability of efficiently searching the state space. However, the uniform sampling strategy cannot help the path planner quickly find an initial solution or converge to the optimal solution. Learning-based strategies can help achieve more efficient search by learning the construction information of the current environment. Fed by a number of successful path planning cases, the designed neural network can learn how to generate promising region in given environments. Then, promising region is used to guide the path planner to heuristically search the regions where a feasible solution probably exists, resulting in a nonuniform sampling strategy. The experiment results demonstrate that the path planning performance improves significantly. Meanwhile, we will investigate different learning-based sampling strategies and compare their performance on path planning problems.

题目:Position Encoding Based Convolutional Neural Networks for Machine Remaining Useful Life Prediction

摘要:Accurate remaining useful life (RUL) prediction is vital for smart manufacturing, which helps to prevent machine failures and ensure system reliability. Recently, many deep learning based methods have been proposed to predict RUL. Among these methods, recurrent neural network (RNN) based approaches show a strong capability of capturing sequential information. This allows RNN based methods to perform better than convolutional neural network (CNN) based approaches on the RUL prediction task. We question this common paradigm and argue that existing CNN based approaches in the literature are not well-designed according to the classic principles of CNN, which hinders their performances. Additionally, the capacity of capturing sequential information is highly affected by the receptive field of CNN, which has been neglected by existing CNN based methods. To solve these problems, we present a series of new CNNs, which show competitive results to RNN based methods. To further improve the performance via well capturing the temporal information, a position encoding scheme is developed to enhance the sequential information encoded by a CNN. Hence, our proposed position encoding based CNN called PE-Net can be further improved and even performs better than RNN based methods. Extensive experiments are conducted on the C-MAPSS dataset, where our PE-Net shows state-of-the-art performance.
