An LSTM autoencoder model was developed for use as the feature extraction model and aStacked LSTMwas used as the forecast model. We found that the vanilla LSTM model’s performance is worse than our baseline. Thus, we propose a new architecture, that leverages an autoencoder for feature extra...

1.1 架构(Architecture) 有许多LSTM架构可供选择。有些体系结构适合于某些序列预测问题,尽管大多数体系结构具有足够的灵活性,可以适应您的序列预测问题,但仍要测试您对架构适用性的假设。 1.2 记忆单元(Memory Cells) 对于给定的序列预测问题或LSTM体系结构,我们无法知道最佳记忆单元数。必须在LSTM隐藏层中测试一组不同...
The CNN may be untrained, so we could want to retrain it by backpropagation fault again from LSTM over numerous input data towards the CNN architecture. Figure 4 shows the architecture of the proposed CNN-LSTM model. The proposed Hybrid model works in various phases, which include pre-...

LSTM Layer Architecture LSTM layers use additional gates to control what information in the hidden state is exported as output and to the next hidden state. These additional gates overcome the common issue with RNNs in learning long-term dependencies. In addition to the hidden state in tradition...
世界模型用来学习控制器发出动作后产生的结果。这种模式也就是现在的rollout算法。在LeCun的论文中，关于这部分的引用是来自论文“Dyna, an integrated architecture for learning, planning, and reacting”，发表于1991年8月。但Jürgen认为，其中提到的集合学习、规划和反应的架构，在此之前就被提出了，正是来自于他们...
