首先利用文献挖掘法构建互联网金融上市公司经营风险水平的评价指标体系，通过指标相关性分析法对指标体系进行分析，达到简化指标体系的目的。然后引入平均差、相关系数的绝对值改进CRITIC客观赋值法并对指标赋权，应用GRAP模型对2015年我国90家互联网金融上市公司的经营风险水平进行评价。再从企业性质的视角对样本进行分析，得出创新投入是影响公司经营风险水平的重要因素。最后，有针对性地提出对策建议。

基于对称扰动采样的Actor-critic算法
Actor-critic方法 对称扰动采样 连续空间 强化学习
2016/1/5
针对传统Actor-critic (AC) 方法在求解连续空间序贯决策问题时收敛速度较慢、收敛质量不高的问题, 提出一种基于对称扰动采样的AC算法框架. 首先, 框架采用高斯分布作为策略分布, 在每一时间步对当前动作均值对称扰动, 从而生成两个动作与环境并行交互; 然后, 基于两者的最大时域差分(TD) 误差选取Agent 的行为动作, 并对值函数参数进行更新; 最后, 基于两者的平均常规梯度或增...

语用学家列文森在研究前指代问题时，逐渐将荷恩等级视作语用推理的重要契机，并以此为基础构建了新格赖斯会话含意理论。列文森认为利用荷恩等级可以推导出话语的潜在数量会话含意。然而，很多学者却认为尽管新会话含意能够自圆其说，但它不能够作为会话含意推导的终极参照，其原因就在于荷恩等级并不具有充分的解释力。语用学家黄衍在构建自己的前指代理论时，甚至完全抛弃了荷恩等级。
一般说来， 有三种具有代表性的视角值得...
