The journey of diving into the world of Knowledge Graph Embeddings through KBGAN (Knowledge Graph Generative Adversarial Network) is an exciting one. This blog will guide you through the necessary steps to get started with KBGAN, providing a user-friendly experience for both beginners and advanced users alike. Let’s explore the dependencies, the usage of the program, and a detailed analogy to aid your understanding.

Dependencies

Before running KBGAN, make sure you have the following dependencies installed:

• Python 3
• PyTorch 0.2.0 (REQUIRED): Be cautious as newer versions of PyTorch are not backward compatible.
• PyYAML
• nvidia-smi

Even though PyTorch 0.2.0 may feel outdated, it’s necessary for this project at the moment. There is no current schedule for support in newer versions, so stick with the specified one.

Usage Instructions

Now that you have everything set up, let’s walk through the usage steps:

1. First, unzip the data.zip file.
2. To pretrain the model, run the following command in your terminal:

python3 pretrain.py --config=config_dataset_name.yaml --pretrain_config=model_name

3. This command generates a pretrained model file.
4. Next, for adversarial training, execute this command:

python3 gan_train.py --config=config_dataset_name.yaml --g_config=G_model_name --d_config=D_model_name

5. Ensure that your G model and D model are both pretrained before running this step.

Parameter Exploration

Feel free to explore and modify parameters in the configuration files. The default parameters align with those reported in the paper for consistent results across experiments.

Troubleshooting Tips

If you experience GPU memory exhaustion during the execution, consider decreasing the test_batch_size in your respective config files. This adjustment may slow down the program’s execution but will not impact the test results.

Understanding the Code: An Analogy

Imagine you are a chef preparing a gourmet meal (the final machine learning model). Before you cook, you need to gather your ingredients (data) and prep them accurately (pretraining the model). In this case, the pretrainer is like the sous-chef who ensures all ingredients are ready and measured before the main cooking starts.

Next, during the adversarial training, it’s like having two chefs (the generator and discriminator) competing to create the best dish. The generator tries to create a gourmet meal that looks irresistible, while the discriminator judges whether the dish meets the standard of excellence. They learn from each other, improving their skills in cooking the perfect meal (finalizing the knowledge graph embeddings).
