2025年3月11日 · 在后来被证明是关键的著作 [55] 中， Kelly 提出了广义似然比检验 (GLRT) 作为一种新的 自适应雷达检测器，用于存在未知的均匀高斯噪声的情况。 该检测器在后续著作中得到了彻底研究和扩展： [56]、 [57]、 [58]、 [59]、 [60]、 [61]。 顾名思义，它是似然比检验 (likelihood ratio test) (LRT) 的扩展。 为了建立这种似然检验，首先为输入信号定义两个联合概率密度函数 (PDF)，一个用于 \mathbf {H}_0，一个用于 \mathbf {H}_1 [55]

2024年12月18日 · Abstract: We generalize the generalized likelihood ratio (GLR) method through a novel push-out Leibniz integration approach. Extending the conventional push-out likelihood ratio (LR) method, our approach allows the sample space to be parameter-dependent after the change of variables.

2007年5月15日 · We have proposed a GLR test for the varying-coefficient function of a varying-coefficient model. Under the null hypothesis, the test statistic has been shown to follow the chi-square distribution asymptotically with scale constant and degree of freedom independent of the nuisance parameters, known as Wilks phenomenon.

2022年12月1日 · Peng et al. (2018) proposed a generalized LR (GLR) method to systematically perform sensitivity analysis for a large class of sample performances with discontinuities. The major steps in the derivation of the GLR are function …

First, programming languages are considerably simpler than natural languages. And secondly, they have very efficient parsing methods, most notably LR. The LR parsing algorithm first precompiles a grammar into an LR parsing table, and at the actual parsing time, it performs shift-reduce parsing guided deterministically by the parsing table.

广义似然比检验 (test of generalized likelihood ratio) [1] 一种似然比检验。 广义（generalized）源自于其不依赖于概括统计量U (x)（summary statistics）的特性，因此广义似然比检验是一种适用场景更加广泛的似然比检验。 广义似然比检验 (test of generalized likelihood ratio) [1] 一种适用场景更为广泛（general）的似然比检验。 广义似然比检验 (test of generalized likelihood ratio)一种似然 …

2006年8月1日 · We describe the behaviour of three variants of GLR parsing: (i) Farshi’s original correction to Tomita’s non-general algorithm; (ii) the Right Nulled GLR algorithm which provides a more efficient generalisation of Tomita and (iii) the Binary Right Nulled GLR algorithm, on three types of LR table.

We propose to partition the grammar into multiple subgrammars, each having its own parsing table and parser. Grammar partitioning helps reduce the overall parsing table size when compared to using a single grammar. We used the GLR parser with an LR(1) parsing table in our framework because GLR parsers can handle ambiguity in natural language.

2024年10月31日 · 谷氨酸受体（glutamate receptor-like, GLRs）家族在植物中被发现已有20多年，序列比对发现，植物GLRs与动物离子型谷氨酸受体（inotropic glutamate receptors, iGluRs）同源。 拟南芥（Arabidopsis thaliana）中有20个GLRs成员，根据进化关系分为3个亚家族。 在其他开花植物中，GLRs编码基因数量繁多。 过去20多年来，研究人员对GLRs在植物中的生物学功能进行了深入挖掘，并结合分子、生理、细胞和结构等多方面研究手段探索GLRs的作用机制。 …
