我们使用这个函数而不是来自tibble的as.tibble(),用来自动将时间序列索引保存为zooyearmon索引。最后,我们将使用lubridate::as_date()(使用tidyquant时加载)将zoo索引转换为日期,然后转换为tbl_time对象以使时间序列操作起来更容易。 sun_spots<-datasets::sunspot.month%>% tk_tbl()%>% mutate(index=as_date(inde...
lstm在时序预测序列有广泛的应用,本文解读lstm seq2seq结构中间张量的形状,帮助更好的理解算法。 本文的代码借鉴GitHub - lkulowski/LSTM_encoder_decoder: Build a LSTM encoder-decoder using PyTorch to make sequence-to-sequence prediction for time series data 对于初学者来说,这图比较有迷惑性。这个lstm方框...

This paper uses multi-factor time series SST data to propose a sequence-to-sequence network with two-module attention (TMA-Seq2seq) for long-term time series SST prediction. Specifically, TMA-Seq2seq is an LSTM-based encoder-decoder architecture facilitated by factor-and temporal-attention ...
The current project is a series of example I have first built in French, but I haven't got the time to generate all the charts anew with proper English text. I have built this project for the practical part of the third hour of a "master class" conference that I gave at the WAQ (...
Long time series forecasting is an important problem with applications in many fields, such as weather forecasting, stock prediction, petroleum production prediction and heating load forecasting. In recent years, the most popular methods for long time series forecasting pay attention to extract local in...
