Oct 28, 2021 · Transformers and Time Series Forecasting Transformers are a state-of-the-art solution to Natural Language Processing (NLP) tasks. They are based on the Multihead-Self-Attention (MSA) mechanism, in which each token along the input sequence is compared to every other token in order to gather information and learn dynamic contextual information.

In today’s article, we will unchain a relatively recent arrival among neural network forecasters: the Transformer model. We will let it loose on a multivariate time series that is characterized by three seasonal components: hours, weekdays, and months. This provides an appropriately complex time series for a neural network to chomp on.

In this work we propose for the first time a transformer-based framework for unsupervised representation learning of multivariate time series.

Multivariate Time Series Transformer Framework. This code corresponds to the paper: George Zerveas et al. A Transformer-based Framework for Multivariate ...

We present a novel framework for multivariate time series representation learning based on the transformer encoder architecture.

In this work we propose for the first time a transformer-based framework for unsupervised representation learning of multivariate time series. Pre-trained models can be potentially used for downstream tasks such as regression and classification, forecasting and missing value imputation. By evaluating our models on several benchmark datasets for multivariate time …

Multivariate TSF datasets are usually organized by time: the values of all N variables are represented as a single vector. However, this only allows ...

28.10.2021 · Multivariate Time Series Forecasting (TSF) datasets have two axes of difficulty: we need to learn temporal relationships to understand how values change over time and spatial relationships to know how variables impact one another. Popular statistical approaches to TSF can struggle to interpret long context sequences and scale to complex ...
