contamination : float, should be in the interval (0, 1], optional (default=0.05).
This parameter is adopted only in anomaly detection task to generate pseudo ground truth.
The amount of contamination of the data set, i.e. the proportion
of outliers in the data set. Used when fitting to define the threshold
on the scores of the samples.

请问可以解释下contamination这个参数的具体含义吗,以及如何在异常检测中发挥作用,谢谢
