The Metapath2vec model from the `”metapath2vec: Scalable Representation

class cogdl.models.emb.metapath2vec.Metapath2vec(dimension, walk_length, walk_num, window_size, worker, iteration, schema)[source]

Bases: cogdl.models.BaseModel

The Metapath2vec model from the “metapath2vec: Scalable Representation Learning for Heterogeneous Networks” paper


hidden_size (int) : The dimension of node representation. walk_length (int) : The walk length. walk_num (int) : The number of walks to sample for each node. window_size (int) : The actual context size which is considered in language model. worker (int) : The number of workers for word2vec. iteration (int) : The number of training iteration in word2vec. schema (str) : The metapath schema used in model. Metapaths are splited with “,”, while each node type are connected with “-” in each metapath. For example:”0-1-0,0-2-0,1-0-2-0-1”.

static add_args(parser)[source]

Add model-specific arguments to the parser.
