Time Evidence Fusion Network

Abstract

1. Introduction

This is the official code implementation project for paper "Time Evidence Fusion Network: Multi-source View in Long-Term Time Series Forecasting". The code implementation refers to [](https://github.com/thuml/Time-Series-Library). Thanks very much for [](https://github.com/thuml/Time-Series-Library)'s contribution to this project.

The Time Evidence Fusion Network (TEFN) is a groundbreaking deep learning model designed for long-term time series forecasting. It integrates the principles of information fusion and evidence theory to achieve superior performance in real-world applications where timely predictions are crucial. TEFN introduces the Basic Probability Assignment (BPA) Module, leveraging fuzzy theory, and the Time Evidence Fusion Network to enhance prediction accuracy, stability, and interpretability.
