Appendix for TopicNet: Semantic Graph-Guided Topic Discovery A Detailed discussion of our work A.1 Limitations

We set the embedding size as 100 and the hidden size as 256. Nvidia GTX 8000 GPU and coded with PyTorch as attached in the supplement. The other settings are same with previous experiments. Due to the bottom layer concept is defined as the word layer in the topic model, all the children nodes of the bottom layer node concept are connected to its ancestor node. Then, the children node "dog" of node "mammal" is connected to the parent node The node "male" is the same setting.
