Multi-party privacy-preserving decision tree training with a privileged party

Science China(Information Sciences) 2024年第8期67卷 253-268页

Currently, a decision tree is the most commonly used data mining algorithm for classification tasks. While a significant number of studies have investigated privacy-preserving decision trees, the methods proposed in these studies often have shortcomings in terms of data privacy breach or efficiency. Additionally,these methods typically only apply to symmetric frameworks, which consist of two or more parties with equal privilege, and are not suitable for asymmetric scenarios where parties have unequal privilege. In this paper,we propose SecureCART, a three-party privacy-preserving decision tree training scheme with a privileged party. We adopt the existing pMPL framework and design novel secure interactive protocols for division,comparison, and asymmetric multiplication. Compared to similar schemes, our division protocol is 93.5–560.4× faster, with the communication overhead reduced by over 90%; further, our multiplication protocol is approximately 1.5× faster, with the communication overhead reduced by around 20%. Our comparison protocol based on function secret sharing maintains good performance when adapted to pMPL. Based on the proposed secure protocols, we implement SecureCART in C++ and analyze its performance using three real-world datasets in both lan and WAN environments. he experimental results indicate that SecureCART is significantly faster than similar schemes proposed in past studies, and that the loss of accuracy while using SecureCART remains within an acceptable range.

Combined UAMP and MF Message Passing Algorithm for Multi-Target Wideband DOA Estimation with Dirichlet Process Prior

引用

Tsinghua Science and Technology 2024年第4期29卷 1069-1081页

作者： Shanwen Guan Xinhua Lu Ji Li Rushi lan Xiaonan luo Guangxi Key Laboratory of Image and Graphic Intelligent Processing Guilin University of Electronic TechnologyGuilin 541004China Guilin Huigu Institute of AI Industrial Technology Guilin 541004China School of Information Engineering Nanyang Institute of TechnologyNanyang 473000China

When estimating the direction of arrival (DOA) of wideband signals from multiple sources, the performance of sparse Bayesian methods is influenced by the frequency bands occupied by signals in different directions. This is particularly true when multiple signal frequency bands overlap. Message passing algorithms (MPA) with Dirichlet process (DP) prior can be employed in a sparse Bayesian learning (SBL) framework with high precision. However, existing methods suffer from either high complexity or low precision. To address this, we propose a low-complexity DOA estimation algorithm based on a factor graph. This approach introduces two strong constraints via a stretching transformation of the factor graph. The first constraint separates the observation from the DP prior, enabling the application of the unitary approximate message passing (UAMP) algorithm for simplified inference and mitigation of divergence issues. The second constraint compensates for the deviation in estimation angle caused by the grid mismatch problem. Compared to state-of-the-art algorithms, our proposed method offers higher estimation accuracy and lower complexity.

对面孔、躯体等视觉线索中情绪信息的整合是社会交往中的重要能力。当前对面孔-躯体情绪整合的研究主要通过改变面孔与躯体的呈现时间、空间排布方式以及调整情绪识别的目标线索等方法,考察面部表情与躯体表情的整合加工。与单独的情绪面孔知觉相比,面孔-躯体的情绪整合呈现出明显的情绪知觉增强效应、面孔情绪知觉的可塑性及情绪加工策略存在个体差异等特点。此外,面孔与躯体知觉整合模型基于不同的加工通路描述了二者的整合机制,但是忽略了情绪和动作在整合加工中的作用。后续研究有必要进一步考察不同加工阶段中面孔与躯体整合的特点,关注面孔-躯体情绪加工的个体差异,探究情绪加工障碍个体的面孔与躯体情绪整合特点。

十三五期间,眉山市环境空气质量显著改善,但实现空气质量稳定达标和持续改善面临较大压力。基于2016-2020年空气自动监测数据,分析了眉山市全域区县十三五期间环境空气质量状况,以期为当地的大气污染防治提供决策参考。研究结果表明:十三五期间,眉山市全域PM_(2.5)、PM_(10)等污染物浓度呈下降趋势,空气质量优良率稳步上升,但O_(3)和NO_(2)等光化学污染物浓度有上升趋势;眉山市全域空气质量稳步改善,颗粒物(PM_(2.5)/PM_(10))浓度下降是当地空气质量改善的主要贡献因子;眉山市PM_(2.5)治理策略成效明显,但O_(3)污染防治进展缓慢,O_(3)已成为当地空气质量进一步改善的制约因子,要进一步提升空气质量,需要实施PM_(2.5)和O_(3)协同治理。
