Grouped time series involve more general aggregation structures than hierarchical time series . With grouped time series, the structure does not naturally disaggregate in a unique hierarchical manner, and often the disaggregating factors are both nested and crossed.
Read moreWhat is TCN in deep learning?
3. Temporal Convolutional Network. Temporal Convolutional Networks, or simply TCN, is a variation of Convolutional Neural Networks for sequence modelling tasks, by combining aspects of RNN and CNN architectures .
Read moreAre CNNs good for time series?
CNNs don’t have the assumption that history is complete: Unlike RNNs, CNNs learn patterns within the time window. If you have missing data, CNNs should be useful . In a way, CNNs can look forward: RNN models only learn from data before the timestep it needs to predict.
Read moreWhat is spatio temporal convolutional neural networks?
A spatial–temporal Convolutional Neural Network is designed to automatically extract spatial–temporal features of the crowd . • The performance of anomaly detection is improved when the analysis is concentrated on the dynamic regions only.
Read moreWhat is N Beats?
N-beats is a deep neural architecture based on backward and forward residual links and a very deep stack of fully-connected layers . The architecture has a number of desirable properties, being interpretable, applicable without modification to a wide array of target domains, and fast to train.
Read moreWhat is multiple time series?
Multiple time series is just that: Multiple series instead of a single series . Multivariate time series is usually contrasted with univariate time series, where each observation at a time t is a vector of values instead of a single value.
Read moreCan LSTM be used for multivariate time series?
In this blog post we’d like to show how Long Short Term Memories (LSTM) based RNNs can be used for multivariate time series forecasting by way of a bike sharing case study where we predict the demand for bikes based on multiple input features.
