VerifiedThe human brain achieves separation between rapid learning and long-term memory consolidation through the collaborative mechanism of the hippocampus and neocortex (complementary learning systems theory).66% similarUnverifiedThe Transformer architecture trades native sequential memory for parallel training capability, whereas RNNs/LSTMs pass state between time steps via hidden vectors and naturally possess sequential memory.65% similarUnverifiedSTDP is a local learning mechanism: if the pre-synaptic neuron fires before the post-synaptic neuron, the connection is strengthened; otherwise it is weakened—entirely based on local information with no need for global error backpropagation.64% similarUnverifiedLSTM 通过引入记忆单元与门控机制（输入门、遗忘门、输出门）来捕捉时间序列中的长期依赖关系64% similarUnverifiedLLM 'memory' is merely a temporary stack of context, which differs fundamentally from human memory that continuously updates neural connections through synaptic plasticity63% similar
