Improving the Performance and Learning Stability of Parallelizable RNNs Designed for Ultra-Low Power Applications
Researchers have developed new recurrent neural network architectures, the Cumulative Memory Recurrent Unit (CMRU) and its variant $\alpha$CMRU, to improve performance and learning stability in ultra-low power applications. These models address gradient blocking issues in previous designs by introducing a cumulative update formulation that enhances gradient flow and reduces initialization sensitivity. The CMRU and $\alpha$CMRU demonstrate competitive or superior performance compared to existing models like LRUs and minGRUs on various benchmarks, particularly for tasks requiring long-range memory retention, while maintaining essential features for analog implementation.
