对数似然(log likelihood) 负对数似然(negative log-likelihood) Reference 似然函数(likelihood function) Overview 在机器学习中,似然函数是一种关于模型中参数的函数。“似然性(likelihood)”和"概率(probability)"词意相似,但在统计学中它们有着完全不同的含义:概率用于在已知参数的情况下,预测接下来的观测结果;似然...
Negative log-likelihood The FAQ entryWhat is the difference between likelihood and probability?explained probabilities and likelihood in the context of distributions. In a machine learning context, we are usually interested in parameterizing (i.e., training or fitting) predictive models. Or, more spe...

moving window-negative log likelihood probability (MWNLLP), is proposed to capture the dependency of samples and further improve the detection performance for the concerned faults. A numerical example and the Tennessee Eastman process (TEP) are adopted to demonstrate the effectiveness of the proposed ...
Also, probability values cannot be negative. The resulting factorization is known as nonnegative matrix factorization (NMF) and it has been used successfully in a number of applications, including document clustering [192], molecular pattern discovery [28], image analysis [122], clustering [171],...
Negative loglikelihood functions for supported Statistics and Machine Learning Toolbox™ distributions all end with like, as in explike. Each function represents a parametric family of distributions. Input arguments are lists of parameter values specifying a particular member of the distribution family ...
