针对线性高斯系统，采用共轭分布实现量测噪声未知情况下的状态估计和噪声方差辨识。(For linear Gaussian system, a conjugate distribution is adopted to estimate system state and identificate measurement noise variance.)

一篇关于变分贝叶斯解决噪声参数未知的论文代码，噪声分布使用了逆威沙特分布构建(A paper code about solving the unknown noise parameters with variable decibel Bayes. The noise distribution is constructed with inverse wissaud distribution)
