信息披露的根本目的是解决信息不对称问题。和传统投资顾问比较,在智能投顾环境下,信息不对称问题在市场变化、算法运行、告知说明和数据安全等方面日趋复杂,亟待解决规制尺度问题、责任模糊问题和利益冲突问题。中国法律对智能投顾领域信息披露的规定不完善,带来实践中的困惑和无序。应当建立智能投顾信息披露法律制度,在不可能采取完全列举方式的情况下,应明确披露的原则,强调披露义务人的自我约束,进行总体方向性的指引;强调差异性和适度性要求,在有序发展和防范风险之间寻求平衡点;选择性披露要以能够实际影响投资者决策为判断依据;通过确立过错推定归责原则来强化违反信息披露义务的责任承担。

量子信息的蓬勃发展,促使人们开始从信息的视角来审视和解决量子力学的基础问题,并取得了非凡的成就。基于量子信息的视角,很多量子力学的本体论问题都获得了全新的阐释。首先,关于信息的定义,其本质是一个认识论问题;其次,在信息和物质之间的关系问题上,尽管量子信息给出了很多启发性的思路,但两者的鸿沟依然没有很好的解释;最后,量子力学的一些基础本体论问题,在信息的视域下均得到了进一步的澄清。

为提高实矩阵集的近似联合对角化的盲源分离性能,避免平凡解,提出了一种基于QR分解的类Jacobi联合对角化算法.利用QR分解的数值稳定性,采用Jacobi旋转矩阵,将分离矩阵分解为多个初等三角矩阵和正交矩阵的乘积,利用Jacobi旋转矩阵的结构及矩阵变换后的相关元素求解最优参数,将高维矩阵最小化问题转化为一系列低维矩阵子问题,提升源信号恢复精度.通过求解简化的Frobenius范数目标函数降低算法复杂度.混合心电信号仿真结果表明,与QRJ2D,LUCJD,EGJLUD算法相比,本文算法在分离精度和收敛速度方面均有一定优势.
