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 ...
Visualization of the estimated clusters (k = 2) using the online version of the GRF algorithm for a two-dimensional time series of the Numenta dataset with anomaly Full size image The excitation factor of the following input neurons is calculated for each input neuron in the same manner as in...
(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 raw dataset is in https://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 conta...

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, ...

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....
and we then demonstrate on an automobiledataset how TICC can be used to learn interpretableclusters in real-world scenarios.1 IntroductionMany applications, ranging from automobiles [Miyajima etal., 2007] to f i nancial markets [Namaki et al., 2011] andwearable sensors [Mörchen et al., 200...
We provide NATOPS dataset in the repo and you can start using CoMTE without downloading the other data sets. In case you want to see more examples, we use HPC data sets in our paper and these are located on Zenodo. After you click download, it will send a request to the owner, and ...
