[FLINK-1707][WIP]Add an Affinity Propagation Library Method
I just finished the initial version of AP implementation and pass some
preliminary test. The input of the program include two files:
1 similarity graph : each line indicates the similarity between two
vertices. if <v1, v2, simi> exists, the user is obligatory to ensure the
existence of <v2,v1, simi>. I am considering validating the graph before run
the algorithm.
2 vertex preference: each line indicates the preference of each vertex.
The outputs format is : <vertexId, exemplarId>, indicating the id of the
vertex and the id of its exemplar.
In the value of each vertex, there is a hashmap storing all the
similarities, responsibilities,availabilities to all its neighbor vertex. There
are updated in the vertex centric iteration.
I still do some test and verification? Any advices?
