New framework evaluates sequence model performance with controllable memory functions

Researchers have developed a new synthetic benchmarking framework to evaluate the performance of various sequence modeling architectures, including recurrent neural networks, convolutional models, Transformers, and structured state-space models. This framework utilizes controllable memory functions, parameterized by \(\\alpha\), to generate synthetic datasets with specific temporal structures such as exponential decay, polynomial decay, impulse functions for long-range dependencies, and Airy functions for sparsity. Experiments conducted using this framework have confirmed existing theoretical insights and uncovered new findings regarding the approximation capabilities, optimization dynamics, and architectural trade-offs of these models.
