Accountability in Government Use of AI: Citizen Concerns and Preferences

open access: yesPublic Administration, EarlyView.
ABSTRACT Government adoption of AI opens the “pandora's box” of accountability, a core aspect of public value. Despite the centrality of governmental AI accountability, citizens' concerns and preferences in holding governments accountable for AI usage remain poorly understood.

基于深度学习的准部分子模型研究核物质状态方程

open access: yesHe jishu
在极端相对论重离子碰撞条件下,精确构建有限重子化学势μB区域的量子色动力学(Quantum Chromodynamics,QCD)物质状态方程(Equation of State,EoS)是当前高能核物理研究的核心难题之一。本研究提出一种基于深度学习的准部分子模型,通过构建三个深度神经网络,成功实现了零μB条件下QCD状态方程的高精度重建。同时,经深入分析四阶广义磁化率χ4B在不同温度和μB下的单调性行为,大致限定了QCD临界点可能存在的区间为(T,μB)=((0.113±0.019) GeV,(0 ...

基于核脉冲峰值序列二维卷积神经网络的核素识别方法

open access: yesHe jishu
基于能谱的核素识别方法受到数值统计局限性的影响,需花费较长时间得到统计结果,导致应用于低计数率的快速核素识别速度较慢、精度较差、泛化性不高。为提升核素识 别的速度和性能,本文提出一种基于核脉冲峰值序列二维卷积神经网络(Two-Dimensional Convolutional Neural Network,2D-CNN)的核素识别方法。实验使用NaI(Tl)探测器在不同探源距下采集低计数率的单一源、混合源以及环境本底的核脉冲序列并将其进行固定长度序列划分作为数据集 ...

透视哲学研究中的计算建模方法 [PDF]

open access: yes, 2005
统哲学研究方法在本质上主要是思辨的,但随着非线性科学与计算技术的迅速发 展,目前哲学研究中也兴起了全新的计算实验方法。对于那些思辨哲学问题,通过计算模型,可以 给出更加形象直观的刻画,从而揭示原先无法认识到的深层内涵。因此,可以把计算化的哲学模 型看作是具有复杂结构的思想实验,它打破传统哲学的非精确性,使得计算资源可以为哲学研究 发挥作用。这为哲学的研究提供了一种具有革命性的新手段。国家自然科学基金项目(60275023) ;国家社会科学基金项目 ...

Production of top Quark pair at the large hadron collider(大型强子对撞机中顶夸克对的产生)

open access: yesZhejiang Daxue xuebao. Lixue ban, 2018
通过分析质心能量为8 TeV的质子-质子对撞实验,对大型强子对撞机上的ATLAS探测器,测量了顶夸克对产生过程pp→t的归一化微分散射截面,该实验数据对胶子部分子分布函数的确定非常重要.采用蒙特卡罗数值计算程序MadGraph以及CT10NNLO和CT14NNLO部分子分布函数,分别计算此过程的归一化微分散射截面,得到了与ATLAS实验相符的结果.进一步,用ATLAS实验数据和本文的理论计算结果,更新CT14NNLO部分子分布函数.结果显示,顶夸克对归一化微分散射截面对部分子分布函数不敏感 ...
