Multiple time series (MTS) have complex temporal and spatial correlations and are widely used in industry, finance, and other fields. Some current MTS prediction algorithms only extract a single time or space feature and ignore the rich features contained in the periodicity of the time series. ...
They have commonly been applied to dense prediction problems, such as semantic segmentation. Wang et al. (2017) proposed an FCN model consisting of three convolutional blocks to extract features from time series. The output is passed through a global average pooling layer and the final label is...
Multivariate time series prediction is a critical problem that is encountered in many fields, and recurrent neural network (RNN)-based approaches have been widely used to address this problem. However, traditional RNN-based approaches for predicting multivariate time series are still facing challenges, ...
Since “prediction” seems to be so useful, you might be tempted to apply a time series prediction model if you have time series data. But time series prediction models are usually computationally intensive, and if you have a lot of data, it will be more computationally intensive. So it’s...
Potential directions toward expansion of the time series, either "horizontally" 鈥 by adding more prediction-specific parameters, or "vertically" 鈥 by generalizing flare into integrated solar eruption prediction, are also explained. The immediate tasks enabled by the disseminated dataset include: ...

这个问题其实在bert-wwm中也有 提到过,就是bert原始的mlm任务中的mask机制是认为每一个token是完全独立的,但实际上token之间是存在相互依赖关系的,比如说 “我爱[mask]”很容易预测出来这个[mask]是"你",对于time series数据而言也是一样,time series data 本身就存在较强的自相关属性,尤其是 近邻的time step,...
Temporal Latent Auto-Encoder: A Method for Probabilistic Multivariate Time Series Forecasting(TLAE),这篇论文实际上站在2016年的NeurlPS经典论文Temporal Regularized Matrix Factorization for High-dimensional Time Series Prediction (TRMF)的肩膀上提出的,其基本思想来自于TRMF中对时间序列矩阵分解,将高维时间序列...
Multivariate time series data in practical applications, such as health care, geoscience, and biology, are characterized by a variety of missing values. In time series prediction and other related tasks, it has been noted that missing values and their mi
Medical predictionPrediction of critical condition in intensive care unit (ICU) becomes one of the current major focuses in hospital healthcare delivery. Most of existing data mining methods only considered single time series signal and worked in original dimension. Consequently, they performed poorly ...
