In this blog post, we will walk you through the exciting journey of implementing LeakGAN for long text generation as discussed in the research paper “Long Text Generation via Adversarial Training with Leaked Information.” Accepted at the Thirty-Second AAAI Conference on Artificial Intelligence, this framework introduces innovative ways to generate coherent text longer than 20 words. Let’s unravel the intricacies of LeakGAN together.

Requirements

Before we jump into the implementation, ensure you have the following environment set up:

• Tensorflow r1.2.1
• Python 2.7
• CUDA 7.5 or newer (for GPU support)

Understanding LeakGAN: An Analogy

To understand LeakGAN, let’s think of a chef (the Generator) preparing a dish (the text) with the help of a food critic (the Discriminator). In traditional methods, the chef gathers ingredients and prepares the dish without feedback until it’s completely cooked. The critic simply tastes the final product and provides feedback, which might be too late!

In LeakGAN, however, the chef is allowed to peek into the critic’s notebook (the high-level extracted features). The critic, while not giving direct instructions, hints at the perfect flavor profile throughout the cooking process by providing subtle nudges. Therefore, the chef incorporates these hints during the entire cooking journey, resulting in a dish that not only tastes better but also mirrors the critic’s expectations.

Key Components of LeakGAN

This architecture specifically consists of:

• Manager Module: A high-level long short-term memory (LSTM) module that guides the Worker module with high-level features.
• Worker Module: Another LSTM that generates the actual text based on current inputs and the guiding goal from the Manager.

Setting Up and Running LeakGAN

Once you have the necessary environment, follow these steps to run the LeakGAN code:

1. Clone the LeakGAN repository from GitHub: LeakGAN Repository.
2. Navigate to one of the folders: Synthetic Data for experiments or Image COCO for a real-world application.
3. Follow the README files in these folders for specific instructions regarding data preprocessing and model training.

Troubleshooting

Here are some common issues you might face while implementing LeakGAN, along with solutions:

• Issue: TensorFlow version incompatibility.
  Solution: Ensure you are using TensorFlow r1.2.1. Consider creating a virtual environment with the specific version.
• Issue: CUDA-related errors.
  Solution: Check that your CUDA version is 7.5 or higher. Ensure proper environment variables such as PATH and LD_LIBRARY_PATH are set.
• Issue: Difficulty in generating coherent text.
  Solution: Revisit your training dataset for quality and size. You may consider increasing the training epochs or adjusting hyperparameters.
