Great article. This may help a lot when learning about zip. I'm planning to build a pure Java deflater/inflater on my own. Believe this may help a lot. Gary Gregory 于2020年3月7日周六 上午10:30写道: > Just FYI:Zip Files: History, Explanation and Implementation > https://www.hanshq.net/zip.html > > Gary >

Hi,     For machine learning centroid cluster algorithm, we often use is Calinsk-iHarabasz score to evaluate which algorithm or how many centers is best for a dataset.     The python lib sklearn implements Calinsk-iHarabasz as sklearn.metrics.calinski_harabasz_score. I think there should be a C
