希望alink 加入 层次聚类的功能实现 .
主要是 凝聚的层次聚类算法: 最小距离,平均距离,最大距离的层次聚类.
层次聚类方法在某些数据挖掘场景中可能是比 k-means更通用和有效的聚类方法, 希望社区有人可以加入此方法的实现, 或者提出相关计划..

Right now, the (condensed) distance matrix is an array of doubles. For my application, that degree of precision is way higher than necessary.
I would benefit substantially from the memory savings …
