MATE: Multi-view Attention for Table Transformer Efficiency

1 code implementation EMNLP 2021 Julian Martin Eisenschlos, Maharshi Gor, Thomas Müller, William W. Cohen

However, more than 20% of relational tables on the web have 20 or more rows (Cafarella et al., 2008), and these large tables present a challenge for current Transformer models, which are typically limited to 512 tokens.

Real-time Neural Radiance Caching for Path Tracing

2 code implementations23 Jun 2021 Thomas Müller, Fabrice Rousselle, Jan Novák, Alexander Keller

Since pretraining neural networks to handle novel, dynamic scenes is a formidable generalization challenge, we do away with pretraining and instead achieve generalization via adaptation, i. e. we opt for training the radiance cache while rendering.

DoT: An efficient Double Transformer for NLP tasks with tables

1 code implementation Findings (ACL) 2021 Syrine Krichene, Thomas Müller, Julian Martin Eisenschlos

To improve efficiency while maintaining a high accuracy, we propose a new architecture, DoT, a double transformer model, that decomposes the problem into two sub-tasks: A shallow pruning transformer that selects the top-K tokens, followed by a deep task-specific transformer that takes as input those K tokens.
