The traditional offensive language detection methods suffer from issues such as inadequate understanding of semantic information and sensitivity to noise in text. To address these problems, this paper proposes a Chinese offensive language detection algorithm based on a pre-trained language model and augmented with a pointer network. Firstly, the algorithm incorporates task prompt information into the text using the prompt layer. Then, it feeds the integrated text with task prompt information into the pre-trained language model RoBERTa to extract deep semantic information and obtain a semantic vector. Subsequently, the generated semantic vector is inputted into the focus layer of the pointer network to obtain a focus vector that strongly relates to offensive language. Finally, by concatenating the semantic vector and focus vector, they are passed through a classification layer for text classification and determining whether it contains offensive language. Experimental results on the Chinese offensive language dataset COLD demonstrate that our proposed method outperforms mainstream methods significantly in terms of detection effectiveness.

This paper introduces a top-down collaborative design methodology rooted in the concept of initiating product development from a holistic perspective, encompassing overall scheme planning, layout design, and subsystem refinement, down to detailed component engineering. This approach transcends software platform constraints and harmoniously integrates with the R&D workflows prevalent across industries, especially in large-scale, interdisciplinary product development endeavors. The core of our proposal revolves around a skeleton model-based framework that encompasses the establishment of a collaborative platform, outlining a top-down collaborative design strategy, and facilitating parallel design efforts across departments. This ensures that product conception stems from a unified vision, with seamless intent communication and efficient multi-disciplinary labor division, ultimately culminating in a comprehensive digital prototype equipped with models suitable for advanced applications like finite element analysis and motion simulation, fostering innovation and efficiency in the entire design lifecycle.

Targeted Adversarial Examples Generating Method Based on cVAE in Black Box Settings

In recent years, adversarial examples has become one of the most important security threats in deep learning applications. For testing the security of deep learning models in adversarial environment,many researches focus on generating adversarial examples quickly and efficiently. In order to solve the problems of existing generative adversarial networks based methods which can not effectively generate the targeted adversarial examples in black box settings, and to improve the temporal performance of gradient-based generating methods,an adversarial examples generating method based on conditional Variational autoencoder(cVAE) is proposed in this paper, where a cVAE is designed elaborately to generate adversarial examples without most of the detailed information about the attacked deep learning models, of which the output can be controlled arbitrarily by these crafted inputs, used to test the robustness of deep learning models against adversarial examples. The experimental results show that the proposed method can achieve a comparable attack success rate and a better temporal performance than the existing gradient-based generating methods in black box environment.

The growth in data volume poses a challenge to query processing. On the other hand, advancements in technology have made multicore CPUs available in many inexpensive servers. so parallel query based on multicore CPU is undoubtedly a solution for query acceleration and cost reduction. In this paper, a parallel query method is proposed and implemented, which rewrites the query execution plan and replaces the original serial scanning operator with a parallel driver operator under the premise that most of the operators do not change, so as to maximize the utilization of CPU and disk resources. Experiments show that it can achieve approximately a 2x speed increase in query processing.

High Sensitivity CQDs-Modified ZnO Nanowire Gas Sensor Fabricated on 3D Substrate for Acetone Detection

The exploration of acetone gas sensors with excellent selectivity and high sensitivity is a critical challenge. The realization of specific adsorption of target gas by gas-sensitive materials and the enhancement of their contact area represent key strategies for improving sensor gas sensing performance. Carbon quantum dots (CQDs) possess abundant active functional groups on their surfaces, which facilitate the specific adsorption of target gas molecules. In this paper, we fabricated CQDs-modified ZnO nanowire gas sensor based on 3D substrate. Evaluation of the sensing performance reveals that the 3D substrate significantly enhances acetone sensitivity at the optimal operating temperature of 300°C in comparison with planar substrate. The improvement is primarily attributed to the increased interaction area between the sensor and the molecules. More notably, the optimal operating temperature for the CQDs-modified gas sensor to detect acetone is reduced to 100°C. At this temperature, the sensitivity of the CQDs-modified gas sensor on the 3D substrate is approximately 35% higher than pristine ZnO sensor at 300°C for 400 ppm acetone. Moreover, the CQDs-modified gas sensor on the 3D substrate exhibits excellent selectivity towards acetone. These results demonstrate that the integration of 3D substrate and CQDs decoration effectively improves both sensitivity and selectivity for acetone detection. © 2001-2012 IEEE.
