Artificial synapse with tunable dynamic range for neuromorphic computing with ion intercalated bilayer graphene

Yuzhi He, Shahin Hashemkhani, Yihan Liu, Daniel Vaz et autres

In neuromorphic computing, a tunable dynamic range in artificial synapses is crucial, as it allows devices to emulate the human brain’s efficiency in processing complex information with analog programmable states. Here, we introduce an electrochemical random-access memory (ECRAM) based on bilayer graphene. …

Position Bias Mitigates Position Bias:Mitigate Position Bias Through Inter-Position Knowledge Distillation

Yifei Wang, Feng Xiong, Yong Wang, Linjing Li et autres

Positional bias (PB), manifesting as non-uniform sensitivity across different contextual locations, significantly impairs long-context comprehension and processing capabilities. Previous studies have addressed PB either by modifying the underlying architectures or by employing extensive contextual awareness training. However, the former approach fails to …
