    Struc2Vec

    Command and Configuration

    • Command:algo(struc2vec)
    • Configurations for the parameter params():
    Name Type
    Default
    Specification
    Description
    ids / uuids []_id / []_uuid / / IDs or UUIDs of nodes to start the walk; all nodes to be selected if not set
    walk_length int 1 >=1 Depth of each walk, i.e. the number of nodes walking through
    walk_num int 1 >=1 Number of walks
    k int / [1,10] Number of layers of the multilayer graph, it should be equal or lower than the diameter of the graph
    stay_probability float / [0,1] The probability of staying at the current level
    window_size int / >=1 Windows size
    dimension int / >=1 Dimension of word vector
    learning_rate float / (0,1) Recommendation is 0.025
    min_learning_rate float / (0,learning_rate) For example: learning_rate * 0.0001
    min_frequency int / >=0 Nodes that occur less than this value are discarded, no node is discarded if the value is 1 or less
    sub_sample_alpha float / / α in the sampling strategy, if equal or lower than 0 means no sampling
    resolution int / >=1 For example: 10, 100
    neg_num int / >=0 Number of words in the negative sampling stage, recommendation is 0~10
    loop_num int / >=1 Number of iterations, recommend lower than 10
    limit int -1 >=-1 Number of results to return; return all results if sets to -1 or not set
