パーティション化されたグラフへのEdgeWiseの適用

16.3.4 パーティション化されたグラフへのEdgeWiseの適用

EdgeWiseは、様々なプロバイダおよび様々な機能があるパーティション化されたグラフに適用できます。

opg4j> var model = analyst.supervisedEdgeWiseModelBuilder().
         setVertexInputPropertyNames("vertex_provider_features").
         setEdgeInputPropertyNames("edge_provider1_features", "edge_provider2_features").
         setEdgeTargetPropertyName("target_property").
         build()

SupervisedEdgeWiseModel model = analyst.supervisedEdgeWiseModelBuilder()
    .setVertexInputPropertyNames("vertex_provider_features")
    .setEdgeInputPropertyNames("edge_provider1_features", "edge_provider2_features")
    .setEdgeTargetPropertyName("target_property")
    .build();

params = dict(edge_target_property_name="target_property",
              vertex_input_property_names=["vertex_provider_features"],
              edge_input_property_names=["edge_provider1_features", "edge_provider2_features"])

model = analyst.supervised_edgewise_builder(**params)

トレーニングまたは推測の対象とするプロバイダを選択できます:

opg4j> var model = analyst.supervisedEdgeWiseModelBuilder().
         setVertexInputPropertyNames("vertex_provider_features").
         setEdgeInputPropertyNames("edge_provider1_features", "edge_provider2_features").
         setEdgeTargetPropertyName("target_property").
         setTargetEdgeLabels("provider1").
         build()

SupervisedEdgeWiseModel model = analyst.supervisedEdgeWiseModelBuilder()
    .setVertexInputPropertyNames("vertex_provider_features")
    .setEdgeInputPropertyNames("edge_provider1_features", "edge_provider2_features")
    .setEdgeTargetPropertyName("target_property")
    .setTargetEdgeLabels("provider1")
    .build();

params = dict(edge_target_property_name="target_property",
              vertex_input_property_names=["vertex_provider_features"],
              edge_input_property_names=["edge_provider1_features", "edge_provider2_features"],
              target_edge_labels=["provider1"])

model = analyst.supervised_edgewise_builder(**params)

基礎となるGraphwiseモデルの各グラフ畳込み層での埋込みのフローを制御する場合は、対象となる接続を有効または無効にできます。デフォルトでは、すべての接続が有効です。

         setEdgeTargetPropertyName("target_property").
         setTargetEdgeLabels("provider1").
         build()
