Transformer-XL: Attentive Language Models Beyond a Fixed-Length Context

Transformer-XL is an advanced neural network architecture designed to overcome the limitations of fixed-length context in language modeling. By introducing a segment-level recurrence mechanism and a novel positional encoding scheme, it captures longer-term dependencies without disrupting temporal coherence. This model achieves state-of-the-art results on various language modeling benchmarks, demonstrating improved performance on both short and long sequences

Key Features

  • Segment-Level Recurrence: Enables learning dependencies beyond fixed-length contexts, effectively capturing long-term relationships in data.
  • Novel Positional Encoding: Maintains temporal coherence across segments, enhancing the model's ability to understand sequence order.
  • Dual Framework Support: Implemented in both TensorFlow and PyTorch, facilitating flexibility in deployment and experimentation.
  • State-of-the-Art Performance: Achieves superior results on benchmarks such as enwiki8, text8, One Billion Word, WikiText-103, and Penn Treebank.
  • Efficient Training and Inference: Optimized for faster evaluation, making it suitable for large-scale language modeling tasks.
