We introduce and make openly accessible a comprehensive, multivariate time series (MVTS) dataset extracted from solar photospheric vector magnetograms in Spaceweather HMI Active Region Patch (SHARP) series. Our dataset also includes a cross-checked NOAA solar flare catalog that immediately facilitates ...
(1)输入部分,time series的每个time step的features 相当于一个句子里的一个token的embedding,但是根据实际经验来看,如果每个timestep的features太少做self attention效果不好,这里作者提供的方法是直接用一个shared的linear层来做升维的操作,看了下源代码确实是这么设计的https://github.com/gzerveas/mvts_transformer/...

The model achieved premium performance compared to other state-of-the-art approaches. Karim et al. (2018) extended the FCN approach with LSTM submodules, which significantly enhanced the performance with a nominal increase in model size and minimal preprocessing of the dataset....
The raw dataset is inhttps://archive.ics.uci.edu/ml/datasets/ElectricityLoadDiagrams20112014. It is the electricity consumption in kWh was recorded every 15 minutes from 2011 to 2014. Because the some dimensions are equal to 0. So we eliminate the records in 2011. Final we get data contain...

being collected by sensors [6]. A time series dataset can be univariate, where a sequence of measurements from the same variable are collected, or multivariate, where a sequence of measurements from multiple variables or sensors are collected [7]. Over the past decade, ...
Inspired by the success of Generative Adversarial Networks (GAN) in image generation, we propose to learn the overall distribution of a multivariate time series dataset with GAN, which is further used to generate the missing values for each sample. Different from the image data, the time series...

Time-series data from multicomponent systems capture the dynamics of the ongoing processes and reflect the interactions between the components. The progression of processes in such systems usually involves check-points and events at which the relationships between the components are altered in response to...
