2018-06-23 18:45 −原理 对数损失, 即对数似然损失(Log-likelihood Loss), 也称逻辑斯谛回归损失(Logistic Loss)或交叉熵损失(cross-entropy Loss), 是在概率估计上定义的.它常用于(multi-nominal, 多项)逻辑斯谛回归和神经网络,以及一些期望极大算法的变... ...
The subject of estimating the p-value of the log-likelihood ratio statistic for multinomial distribution has been studied extensively in the statistical literature. Nevertheless, bioinformatics laid n U Keich,N Nagarajan - Algorithms in Bioinformatics, International Workshop, Wabi, Bergen, Norway, Septem...
没有什么原因导致New Keynesian model适合线性展开，因为这个断言本身是错误的。另外那些展开项叫高阶无穷...
You can start by creating a custom probability distribution object that includes the necessary methods for calculating the negative log likelihood. Since you are using a power-law distribution, you've already implemented the logarithm of the probability density function (‘...
I am using dfittool to fit a 1-dimensional data into a statistical distribution and each attempt produces a log-likelihood value. As far as I understood, the higher this value the better the distribution represents the data. My question is how to calculate that log-likelihood value in a m-...
