steel ewc test package

Introduction

This project aims to provide a method to replicate our experiment results. We are expected to utilize Elastic Weight Consolidation (EWC) algorithm to improve the performance of multivariate time-series prediction.

Model Choice

This project provides eight algorithm to choose, including MLP / CNN/ GDN / RNN/ GRU/ LSTM/ LSTMVAE / Transformer.
