WebGaf-cnn This repository contains an implementation of a multivariate time series to multivariate time series regression model using gramian angular field encoding to represent time series as images. It was inspired by the framework proposed by Z. Wang and T. Oates in [1] and was extended to multivariate problems. WebThen the time series can be transformed into a Gramian Angular Summation Field (GASF) when the cosine of the sum of the angular coordinates is computed or a Gramian Angular Difference Field (GADF) when the sine of the difference of the angular coordinates is computed. It is implemented as pyts.image.GASF and pyts.image.GADF.

"WebAug 30, 2024 · Note that the Gramian Angular Field (GAF) does not apply the Gram Matrix directly (in fact, each value of the time series is a scalar, not a vector). The first step in computing the GAF is to normalize the time series to be in the range [-1, +1]. Let’s assume we are given a time series X = { x 1, x 2, …, x N }. " - Gasf python
