This work addresses the limitation of Transformers in lacking an explicit knowledge storage mechanism, which hinders efficient retention and retrieval of learned information. To overcome this, the authors propose a chaptered sparse memory bank, where learnable memory tokens are queried by the Transformer via cross-attention. Inspired by Mixture-of-Experts, a dynamic chapter routing strategy selectively activates relevant subsets of memory, enabling scalable knowledge access while maintaining computational efficiency. The approach expands memory capacity to 262K tokens—introducing a new scaling dimension beyond model parameters—without incurring prohibitive computational overhead. Experiments demonstrate that, under matched FLOPs, the proposed model outperforms standard Transformers in both pretraining and instruction fine-tuning tasks, while also exhibiting substantially improved knowledge retention and robustness against catastrophic forgetting in continual learning scenarios.
This study addresses the nonlinear time-series prediction task of the NARMA-10 benchmark. We systematically compare quantum reservoir computing (QRC), classical echo state networks (ESNs), long short-term memory (LSTM) networks, and a hybrid quantum-classical QLSTM under a unified experimental framework. Prediction accuracy is evaluated via normalized root-mean-square error (NRMSE), while computational resource consumption and inference latency are rigorously quantified—establishing, for the first time, a sustainability-oriented evaluation paradigm for quantum time-series modeling. Results demonstrate that QRC achieves prediction accuracy comparable to LSTM and ESN, yet with substantially reduced parameter count, memory footprint, and forward-inference latency—yielding superior energy efficiency. This work not only validates QRC’s practical viability in resource-constrained edge environments but also pioneers a green, low-overhead pathway for quantum-enhanced time-series modeling.
