Informer: Beyond Efficient Transformer for Long SequenceTime- series ForecastingHaoyi Zhou,1 Shanghang Zhang,2 Jieqi Peng,1 Shuai Zhang,1 Jianxin Li,1 Hui Xiong,3 Wancai Zhang41 Beihang University2UC Berkeley3 Rutgers University4 SEDD Company{zhouhy, pengjq, zhangs, real-world applications require the prediction of longsequence time- series , such as electricity consumption plan-ning. Long Sequence time- series forecasting (LSTF) demandsa high prediction capacity of the model, which is the abilityto capture precise long-range dependency coupling betweenoutput and input efficiently. Recent studies have shown thepotential of Transformer to increase the prediction , there are several severe issues with Transformerthat prevent it from being directly applicable to LSTF, includ-ing quadratic time complexity, high memory usage, and in-herent limitation of the encoder-decoder architecture.}
Time-series forecasting is a critical ingredient across many domains, such as sensor network monitoring (Papadimitriou and Yu 2006), energy and smart grid management, eco-nomics and finance (Zhu and Shasha 2002), and disease propagation analysis (Matsubara et al. 2014). In these sce-narios, we can leverage a substantial amount of time-series
