异常检测(Anomaly Detection)方法与Python实现 异常检测(Anomaly detection)是机器学习的常见应用,其目标是识别数据集中的异常或不寻常模式。尽管通常被归类为非监督学习问题,异常检测却具有与监督学习相似的特征。在异常检测中,我们通常处理的是未标记的数据,即没有明确的标签指示哪些样本是异常的。相反,算法需要根据数据...
- `sktime`：一个针对时间序列分类和异常检测的Python库，它提供了许多专门针对时间序列数据的机器学习算法。8. 异常检测框架：- `PyOD`：一个流行的Python工具包，用于检测多元数据中的异常对象，包括各种孤立森林、局部异常因子（LOF）等算法。9. 自然语言处理：- `nltk`或`spaCy`：在处理文本数据时，可以使用这...
