FAQ

What is the main innovation of Transformer-XL?

It introduces segment-level recurrence and adaptive memory to enable modeling of longer sequences without full recomputation.

Is Transformer-XL suitable for production deployment?

It's primarily a research library; for production, consider fine-tuning and integrating with optimized inference frameworks.

What datasets does it support out-of-the-box?

Pre-configured for enwik8, enwiki8, text8, and one-billion-word benchmark.

Does it require PyTorch?

Yes, it's implemented in PyTorch 0.4.1 or compatible versions.

Are there pre-trained models available?

Yes, checkpoints for various model sizes on WikiText-103 and other corpora are provided in the repository.

How does it compare to GPT models?

Transformer-XL excels in fixed-length long-context modeling but lacks the decoder-only autoregressive design of GPT.
