Question 1

How can I use this code with my own structured dataset?

Accepted Answer

You'll need to adapt the preprocessing scripts in /TensorFlow_implementation/ to handle your data format, similar to the WikiBio integration, and modify hyperparameters in the training scripts. Expect significant data preparation work, as outlined in the README's preprocessing steps.

Question 2

What is the copy network and when should I use it?

Accepted Answer

The copy network allows the model to directly copy tokens from the input structured data, useful for rare or domain-specific terms. Use trainer_with_copy_net.py if your data has many out-of-vocabulary words, as it enhances handling of such tokens compared to the standard decoder.

Question 3

Is LSTM or transformer better for text generation from tables?

Accepted Answer

LSTMs, as used here, are older but effective for sequence tasks and are replicated from the original paper; transformers like GPT often outperform for fluency but require more data and compute. This implementation focuses on LSTM-based order-planning for reproducibility.

Question 4

How do I reduce memory usage when training this model?

Accepted Answer

Limit the dataset size by adjusting the 'data_limit' parameter in preprocessing scripts, as suggested in the README for hosts with less than 12GB RAM. Also, consider using smaller batch sizes in the training scripts to manage GPU memory.

Question 5

Can I run this with TensorFlow 2.x instead of tensorflow-gpu?

Accepted Answer

The code is written for an older TensorFlow version; migrating to TF 2.x may require code changes due to API differences. It's recommended to use the specified tensorflow-gpu for compatibility, though updates might be needed for future support.

Question 6

What are the performance benchmarks for this model?

Accepted Answer

Since trained models aren't provided, performance depends on training data and hyperparameters. Refer to the original research paper for expected metrics, and use TensorBoard to monitor loss during training, as shown in the README's visualization examples.
