在Python中,可以使用rouge-score库来计算Rouge评价指标。首先,需要安装rouge-score库: ``` pip install rouge-score ``` 然后,可以使用以下代码调用Rouge评价指标: ```python from rouge_score import rouge_scorer # 创建Rouge评价器 scorer = rouge_scorer.RougeScorer(['rouge1', 'rouge2', 'rougeL'], us...
ROUGE即Recall和Precision的调和平均值, 这个概念和机器学习中的F1-score类似 : ROUGE=Recall∗PrecisonRecall+Precision 可以指定n-gram对其进行变形. 首先需要安装库 !pip install evaluate !pip install rouge-score 运行下面的代码: importevaluaterouge=evaluate.load('rouge')predictions=["Transformers Transformers ...

rouge-chinese库计算rouge-L score时不再需要生成最长子序列,就可以直接计算出最长子序列的长度,并得出最终的rouge-L score。最长子序列的生成是算法中内存消耗最大的一块,由于其中含有递归算法,他会占用大量的栈,尤其是在遇到长文章时,容易导致内存溢出或栈溢出的问题。rouge-chinese库成功的绕过了这一步骤。

F1分数(F1 Score) F1分数是一个重要的性能指标,用于综合评估分类模型的精确率(Precision)和召回率(Recall)。它特别适用于类别不平衡的数据集,因为它能够平衡这两个指标的影响。 F1分数的计算公式为: F1=2×(Precision×Recall)/(Precision+Recall) 1.
