Negative Log Likelihood表示为: −logL(x1,⋯,xm|W)−logL(x1,⋯,xm|W) 根据样本独立性,上式作出以下变换: −logL(x1,⋯,xm|W)=−logm∏j=1L(xj|W)=−m∑j=1logL(xj|W)−logL(x1,⋯,xm|W)=−log∏j=1mL(xj|W)=−∑j=1mlogL(xj|W) 注意到上式...
We assume that the log-likelihood of data Y depends on the N × L factors matrix F and J × L loadings matrix W only through Λ. The number of observations is N, number of components is L and number of features is J. For notational simplicity, here we use fil to denote ...
The first one will print them all with equal likelihood; the second one will print a half the time, and each other option a quarter of the time; the third will print c half the time, and each other option a quarter of the time. This can be a bit unintuitive: for a lot of ...
Learning above objective is equivalent to maximizing the likelihood of observing such pairwise ranking relations rui > ruj, which can be replaced by other objectives used in implicit CF problems, such as marginal hinge loss [43] and binary cross-entropy loss [19]. The most widely used pns(j...
we used the edgeR functions glmQLFit and glmQLFTest to perform a quasi-likelihood dispersion estimation and hypothesis testing that assigns FDR values to each gene. In the track scRNAseq plots in Fig.3and Additional file 1: Figure S5, a positive log 2 fold change value for Clone X relativ...

(SN), that was immunofluorescence-negative for the plasmalemmal dopamine transporter (DAT), with ~40% smaller cell bodies. These neurons were negative for aldehyde dehydrogenase 1A1, with a lower co-expression rate for dopamine-D2-autoreceptors, but a ~7-fold higher likelihood of calbindin-d28...

To determine the best-fit parameters, we calculated a likelihood score for each parameter set (ρ, μ) using the distribution of proportions of shared barcodes over five independent runs of the simulation. This was computed as the sum of the likelihoods of observing the proportion of shared ...
