To effectively estimate the RUL of mechanical systems, the long short-term memory (LSTM)-based multi-layer self-attention (MLSA) (LSTM-MLSA) method is proposed by designing MLSA mechanism and LSTM, to improve the modeling precision and computing efficiency. In the MLSA mechanism, the multi-...

If your training/validation loss are about equal then your model isunderfitting. Increase the size of your model (either number of layers or the raw number of neurons per layer) The two most important parameters that control the model arernn_sizeandnum_layers. I would advise that you always...
The purposes of this research are to build a robust and adaptive statistical model for forecasting univariate weather variable in Indonesian airport area and to explore the effect of intermediate weather variable related to accuracy prediction using single layer Long Short Memory Model (LSTM) model and...
❶ Missing Value Layer:缺失的特征可根据对应特征的分布去自适应的学习出一个合理的取值。 ❷ KL-divergence Bound:通过物理意义将有关系的 Label 关联起来,比如p(点击) * p(转化) = p(下单)。加入一个 KL 散度的 Bound,使得预测出来的 p(点击) * p(转化) 更接近于 p(下单)。但由于 KL 散度是非...

1.2 Transformer Layer. 上一步对特征映射到低维表征后,便使用transformer layer来学习每一个时间序列的更加深层次的表征,来捕获与其他时间序列的相关性,众所周知,相比于RNN和LSTM,transformer更高效和有效。 transformer layer仍然是常规的做法,由多个Self-attention Layer组成的multi-head self-attention。(论文的公式写...
多头注意力卷积长短期记忆神经网络(Multi-Head Attention Convolutional LSTM,MHAC-LSTM)是一种用于处理多变量时间序列预测问题的深度学习模型。它将卷积神经网络(CNN)和长短期记忆神经网络(LSTM)结合起来,并使用多头注意力机制来增强模型的表达能力。 每个输入时间序列的变量都经过一个卷积层进行特征提取,并将卷积层的输...
