基于实例的解释方法选择数据集的特定实例来解释机器学习模型的行为或解释底层数据分布。 基于实例的解释大多与模型无关,因为它们使任何机器学习模型都更具可解释性。与模型无关方法的区别在于,基于实例的方法通过选择数据集的实例而不是通过创建特征摘要(例如特征重要性或部分依赖性)来解释模型)。 只有当我们能够以人类...
In Machine Learning, in Support Vector Machines (SVMs), bilinear forms define kernel functions that measure similarity between data points. In Differential Geometry, the metric tensor, which defines distances and angles on a manifold, is a bilinear form on the tangent space. In Economics, payoff ...

f(R)theory represents the pioneering extension of GR achieved through modifying the action, where the Ricci scalarRis supplanted with the generalized function [1]. Researchers have extensively utilized various approaches in this context to investigate the feasibility of self-gravitating structures [2,3...
F值,亦被称做F-measure,是一种量测算法的精确度常用的指标,经常用来判断算法的精确度。目前在辨识、侦测相关的算法中经常会分别提到精确率(precision)和召回率(recall),F-score能同时考虑这两个数值,平衡地反映这个算法的精确度。 The traditional F-measure or balanced F-score (F1 score) is the harmonic mea...
Optimization of various RF and SVM parameters for the development of classification models The comparison between different machine learning algorithms revealed that SVM and RF had comparable performances in terms of Accuracy, Precision, F-measure, MCC and ROC values on the training dataset...
Vertrauen in die Sicherheit von Impfungen (β = 0,514, p < 0,001) und eine Influenza-Impfung (β = 0,153, p < 0,001) in der letzten Saison sind die stärksten Prädiktoren für die Pneumokokken-Impfintention. Zudem zeigt die Einschätzung des von einer Pneu...
