The duration of one well-observed spike is quantitatively shown to be within a few percent of 8 ms despite the 20 ms resolution of the data.doi:10.1002/2016JA022615Nita, Gelu M.Gary, Dale E.Journal of Geophysical Research Space Physics...
A computer program is said to learn from experience E with respect to some class of tasks T and performance measure P if its performance at tasks in T, as measured by P, improves with experience E. 整段英文有点抽象难懂对吗?首先注意到两个词 computer program 和 learn,翻译成中文就是机器 ...

GetTangent(Single, SKPoint) Computes the corresponding tangent from the specified distance along the path. GetTangent(Single) NextContour() Move to the next contour in the path. SetPath(SKPath, Boolean) Reset the path measure with the specified path. SetPath(SKPath) Applies...
机器学习(ML),自然语言处理(NLP),信息检索(IR)等领域,评估(Evaluation)是一个必要的 工作,而其评价指标往往有如下几点:准确率(Accuracy),精确率(Precision),召回率(Recall)和F1-Measure。 1、准确率、精确率、召回率、F值对比 准确率/正确率(Accuracy)= 所有预测正确的样本 / 总的样本 (TP+TN) ...
Controls the precision of the measure. Values greater 1 increase the precision (and possibly slow down the computation). Remarks The path must remain valid for the lifetime of the measure object, or until SetPath(SKPath, Boolean) is called with a different path (or null), since the measure...

"samples(样本)"仅适用于 multilabel problems (多标签问题)。它 does not calculate a per-class measure (不计算每个类别的 measure),而是计算 evaluation data (评估数据)中的每个样本的 true and predicted classes (真实和预测类别)的 metric (指标),并返回 (sample_weight-weighted) 加权平均。
