Ada-MSHyper: Adaptive Multi-Scale Hypergraph Transformer for Time Series Forecasting

✨ This repo is the official implementation of Adaptive Multi-Scale Hypergraph Transformer for Time Series Forecasting.

1 The framework of Ada-MSHyper

Ada-MSHyper is proposed to promote more comprehensive pattern interactions at different scales, which consist of four main parts: Multi-scale Feature Extraction (MFE) Module, Adaptive Hypergraph Learning (AHL) Module, Multi-Scale Interaction Module, and Multi-Scale Fusion Module. The overall framework of Ada-MSHyper is shown as follows:

2 Prerequisites

• Python 3.8.5
• PyTorch 1.13.1
• math, sklearn, numpy, torch_geometric

3 Datasets && Description

📦 You can download the all datasets from datasets. All the datasets are well pre-processed and can be used directly.
