+## Power Iteration Clustering (PIC)
+
+Power Iteration Clustering (PIC) is a scalable graph clustering algorithm
+developed by <a
href=http://www.cs.cmu.edu/~frank/papers/icml2010-pic-final.pdf>Lin and
Cohen</a>.
+From the abstract: PIC finds a very low-dimensional embedding of a dataset
+using truncated power iteration on a normalized pair-wise similarity matrix of
the data.
+
+`spark.ml`'s PowerIterationClustering implementation takes the following
parameters:
+
+* `k`: the number of clusters to create
+* `initMode`: param for the initialization algorithm
+* `maxIter`: param for maximum number of iterations
+* `srcCol`: param for the name of the input column for source vertex IDs
+* `dstCol`: name of the input column for destination vertex IDs
+* `weightCol`: Param for weight column name
