Bidirectional Long-Range Parser for Sequential Data Understanding
This addresses scalability limitations for researchers and practitioners working with long-sequence vision and language tasks, though it appears incremental as it builds on existing transformer frameworks.
The authors tackled the problem of transformer inefficiency with long-sequence data by introducing BLRP, a novel attention mechanism combining local sliding windows with global bidirectional latent synthesis, achieving competitive results on Long-Range-Arena and CIFAR benchmarks while demonstrating computational efficiency.
The transformer is a powerful data modelling framework responsible for remarkable performance on a wide range of tasks. However, they are limited in terms of scalability as it is suboptimal and inefficient to process long-sequence data. To this purpose we introduce BLRP (Bidirectional Long-Range Parser), a novel and versatile attention mechanism designed to increase performance and efficiency on long-sequence tasks. It leverages short and long range heuristics in the form of a local sliding window approach combined with a global bidirectional latent space synthesis technique. We show the benefits and versatility of our approach on vision and language domains by demonstrating competitive results against state-of-the-art methods on the Long-Range-Arena and CIFAR benchmarks together with ablations demonstrating the computational efficiency.
