DeepWalk

DeepWalk uses short random walks to learn representations for vertices in graphs.

Usage

Example Usage

$deepwalk --input example_graphs/karate.adjlist --output karate.embeddings

--input: input_filename

1. --format adjlist for an adjacency list, e.g:

   1 2 3 4 5 6 7 8 9 11 12 13 14 18 20 22 32
   2 1 3 4 8 14 18 20 22 31
   3 1 2 4 8 9 10 14 28 29 33
   ...

2. --format edgelist for an edge list, e.g:

   1 2
   1 3
   1 4
   ...

3. --format mat for a Matlab MAT file containing an adjacency matrix

   (note, you must also specify the variable name of the adjacency matrix --matfile-variable-name)

--output: output_filename

The output representations in skipgram format - first line is header, all other lines are node-id and d dimensional representation:

34 64
1 0.016579 -0.033659 0.342167 -0.046998 ...
2 -0.007003 0.265891 -0.351422 0.043923 ...
...
