UnverifiedRNNs face the vanishing gradient problem, whose essence is the cascading multiplication effect under the chain rule, making it difficult to learn long-range historical information.80% similarUnverifiedModels in the RNN era read word by word strictly from left to right without looking back, causing severe decay of contextual information as the hidden state advances, i.e., the long-term dependency problem.79% similarUnverified自回归解码存在结构性缺陷，早期输出偏离事实会导致后续内容在错误方向上越走越远，形成雪崩效应69% similarUnverifiedThe core pain point of traditional RNNs (including GRU and LSTM) is that historical information decays at an exponential rate during backpropagation, leading to vanishing gradients.69% similarUnverifiedSetting a fixed timestamp or TTL for memories cannot adapt to unpredictable rates of data change—deleting too early loses valid information, while deleting too late allows stale data to continue causing problems.67% similar
