Here the Encoder–Decoder–SLSTM (ED-SLSTM) model is compared with LightGBM, LSTM, Bi-LSTM, LSTM-Attention and CEEMDAN-LSTM models under the framework of TP-TPP, respectively. The performance of each evaluation index in ED-SLSTM is closer to the real value than them of other models. The...

A more elaborate autoencoder model was also explored where two decoder models were used for the one encoder: one to predict the next frame in the sequence and one to reconstruct frames in the sequence, referred to as a composite model. … reconstructing the input and predicting the future can...

摘要: State-of-the-art Chinese word segmentation systems typically exploit supervised modelstrained on a standard manually-annotated corpus,achieving performances over 95% on a similar standard testing corpus.However, the performances may drop significantly when the same models are applied onto Chinese ...
In this paper, the author proposed three models based on LSTM: 1) LSTM Autoencoder Model: This model is composed of two parts, the encoder and the decoder. The encoder accepts sequences of frames as input, and the learned representation generated from encoder are copied to decoder as initial...
