Humanoid robot has broad application prospects in services, entertainment, medical care, rescue, and other fields. Therefore, research on the stable walking problem of humanoid robot is particularly important. To solve this problem, this paper proposes a gait control method for humanoid robot according to reinforcement learning. We established a linkage model for humanoid robot and simplified it into a linear inverted pendulum model which was used for motion control of humanoid robot. Using DDPG network as an intelligent agent to train humanoid robot in gait control in a simulation environment. Due to the combination of DDPG and DQN structure, the stability and convergence of strategy network and critical network have been improved. The MATLAB simulation results show that under the action of the DDPG algorithm, the humanoid robot can walk smoothly along the predetermined trajectory through reinforcement learning. © 2024 SPIE.

The sparse adversarial attack has attracted increasing attention due to the merit of a low attack cost via changing a small number of pixels. However, the generated adversarial examples are easily detected in vision since the perturbation to each pixel is relatively large. To achieve imperceptible and sparse adversarial attacks, this article formulates a bi-objective constrained optimization problem, simultaneously minimizing the 0 and 2 distances to the original image, and proposes a dual-population-based constrained evolutionary algorithm to solve it. The proposed method solves the optimization problem by evolving two populations, where one population is responsible for finding feasible solutions (i.e., successful attacks) and the other one is to minimize both the 0 and 2 distances. Moreover, a population initialization strategy and two genetic operators are customized to accelerate the convergence speed. Experimental results indicate that the proposed method can achieve high success rates with low attack costs, and strikes a better balance between the 0 and 2 distances than state-of-the-art methods. © 2020 IEEE.

This study aims to evaluate the effectiveness of an emerging software engineering development method through AB testing experiments. As a commonly used online experimental method, AB testing is used to compare the performance of two or more solutions. It has been widely used in the software development process to optimize user experience and function implementation. This study proposes a new development framework that combines AB testing and software testing, which quantifies the impact of different development strategies on software quality by constructing a correlation matrix. In order to verify the effectiveness of this method, this paper designed a series of experiments and implemented AB testing in multiple software projects. Experimental results show that by accurately adjusting the variable combinations in AB testing, software stability and user satisfaction can be significantly improved. In addition, this paper also develops a set of computer algorithm models to simulate different development scenarios and predict the potential benefits of new development methods through simulation technology. Through the analysis of simulation results, this article found that projects using new development methods have improved in key performance indicators, especially in shortening development cycles and reducing defect rates. The development method that combines AB testing and software testing not only improves the quality of software products, but also enhances the flexibility and response speed of the development process. © 2024 Copyright held by the owner/author(s).

Optical measurement techniques have emerged as a promising alternative to traditional invasive methods for stress recovery. Recent developments in artificial intelligence have enabled researchers to harness Physics-Informed Neural Networks (PINNs) for solving complex physics-based problems, including stress field recovery from photoelastic fringes. This paper explores the potential of PINNs for non-invasive stress analysis, presenting a novel methodology that integrates photoelastic fringes and physical stress distribution constraints within a deep learning framework. Our results demonstrate the model's robustness in handling diverse stress patterns and its ability to accurately recover stress distributions even when trained on significantly reduced datasets. A comparative analysis shows our PINN-based model's performance surpassing or closely matching existing methods like PhotoelastNet, underscoring its competitive advantage in stress recovery. © COPYRIGHT SPIE.

In recent years, depth estimation has witnessed significant advancements because of the development of deep learning. It's important to note that depth estimation tasks focus solely on predicting the depth of each pixel in an image and do not include object detection or object recognition. Depth estimation is the use of pixel transformations in the image to obtain distance information from each point in the scene to the camera to generate a depth map. Object detection is the process of classifying and localizing an image, given a picture, so as to identify the objects in the picture and determine their location. To overcome this limitation and integrate object detection into the depth estimation process, this paper proposes a novel self-supervised monocular depth estimation algorithm that leverages an attention mechanism. By combining object detection and depth estimation, a real-time multi-task model is designed to enable simultaneous detection and depth estimation of objects. The framework comprises four essential components: an object detection sub-network, a depth estimation sub-network, a lateral sharing unit, and an attention loss. These components work collaboratively to enhance distance estimation accuracy for objects and improve the object detection performance. Throughout experiments, it is evident that the proposed approach can effectively estimate distances to objects and enhances the accuracy of object detection. © 2024, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.

By incorporating the latest external knowledge, large language models (LLMs) can modify their internal memory. However, in practical applications, LLMs may encounter outdated information, necessitating the filtering of such data and updating of knowledge beyond internal memory. This paper explores whether LLMs can selectively update their memories based on the time constraints between internal memory and external knowledge. We evaluate existing LLMs using three types of data that exhibit different time constraints. Our experimental results reveal the challenges most LLMs face with time-constrained knowledge and highlight the differences in how various LLMs handle such information. Additionally, to address the difficulties LLMs encounter in understanding time constraints, we propose a two-stage decoupling framework that separates the identification and computation of time constraint into a symbolic system. Experimental results demonstrate that the proposed framework yields an improvement of over 60% in ChatGPT's performance, and achieves a 12-24% enhancement in state-of-the-art LLM GPT-4. © 2024 Association for Computational Linguistics.

In conventional high-voltage live work, operators are required to work near high-voltage cables, which poses risks such as falling and getting an electric shock. To promise the worker's safety, regional breakout of power is one of the common methods that the power sector would deploy. However, with the development of society, a lot of trouble will be brought about due to the economic loss and social impact caused by regional power outages, which pose higher requirements for the power sector. Hence, it is demanding to carry out a safe and effective method for high-voltage live work without power failure. In such a context, we have developed a dual-arm collaborative robotic system for high-voltage live work. The system includes a human-computer interaction interface and a pair of Omega handles, which allow workers to operate remotely at the control center. In laboratory experiments, the system can accurately complete stripping, trimming, and wiring operations. Also, some actions are pre-programmed inside the control system to realize simple operations automatically. This dual-arm robot collaboration system with a teleoperation function can greatly reduce the labor intensity of workers and ensure their safety. © 2023 IEEE.

Improving the risk prevention capability of grid operations is a crucial requirement for smart resilient grids, where efficient dispatch and scheduling of delivery capacity play a pivotal role in enhancing grid resilience. Therefore, it is necessary to develop targeted intelligent dispatch algorithms based on operational data. To address this issue, this paper proposes a framework with inherent constraints and utilizes reinforcement learning using recursive neural networks. A constraint module is designed to identify available vehicle combinations based on de-livery capacity, allocate goods considering vehicle number, load, and size constraints, and generate delivery routes sequentially. Additionally, a reinforcement learning model is introduced, using negative trip length as a reward signal, optimizing parameters of the recursive neural network through policy gradient methods to automatically improve strategies for selecting optimal deliv-ery routes with improved vehicle combinations. To validate the effectiveness of this algorithm, extensive experiments were conducted using both real-world application validation data and the TSPLIB public dataset. Within a limited computational budget, the proposed algorithm outperforms several mature methods in terms of effectiveness and real-time performance, achieving near-optimal results in Euclidean graphs with nearly 100 nodes. These results demonstrate that this approach effectively addresses the intelligent scheduling of delivery capacity in digital twin systems for power storage © 2024 IEEE.
