ETALON IMAGES: UNDERSTANDING THE CONVOLUTION NEURAL NETWORKS
CNN deep learning manifold learning affine transformations graphs etalons
2018/3/30
In this paper we propose a new technic called etalons, which allows us to interpret the way how convolution network makes its predictions. This mechanism is very similar to voting among different expe...
论企业社会责任信息的网络沟通——基于零售百强网站的文本分析
企业社会责任 CSR网络沟通 信息位置 零售百强
2018/3/30
企业的社会责任行为必须经过沟通才能产生预期价值。通过考察我国零售百强网站中企业社会责任沟通情况，将其从高到低划分为集中沟通、零散沟通和无沟通三个等级。分析发现，尽管近八成的企业已将企业网站作为企业社会责任沟通的重要渠道，但集中沟通企业仅占四成，而且沟通的有效性和创新性不足，本土企业和外资企业在企业社会责任网络沟通方面存在差异性。建议推出企业社会责任网络沟通典型案例，制定包括网络沟通的《CSR沟通操...
