Informer: Beyond Efficient Transformer for Long Sequence Time-Series Forecasting 是AAAI2021的最佳论文之一,提出了对Transformer的三种改进,有效解决了long sequence time-series forecasting(LSTF)问题。 1 简介 1.1 什么是LSTF问题? time-series forecasting是机器学习中常见的一类问题:给定时序数据,对未来的数据点进...
时间序列预测在工业界有着广泛的应用,比如预测银行交易量、电力消耗和云服务访问量等。准确预测这些指标可以帮助企业有效调配资源,避免服务中断。虽然短期预测相对简单,但长期预测(如未来一个月的访问量)却极具挑战性。长时间序列预测(LSTF)因为预测序列长度长,对模型的要求也更高。为了解决长距离依赖问题,Informer提出...

在网络图中,ES代表最早开始时间,是指某个活动能够开始的最早时间点。EF则代表最早结束时间,它等于ES加上该活动所需的时间。LS指的是最晚开始时间,是活动必须开始的最晚时间点,以确保整个项目按预定时间完成。LF代表最晚结束时间,即活动必须完成的最晚时间点,同样是为了保证项目按时完成。TF,即总...
在项目管理中的网络图中,ES(Early Start)、EF(Early Finish)、LS(Late Start)、LF(Late Finish)、TF(Total Float)和FF(Free Float)是关键路径方法(Critical Path Method,CPM)中用于描述活动和事件时间的重要概念。 1. 在网络图中ES、EF、LS、LF、TF、FF的基本介绍 ...
在网络图中ES、EF、LS、LF、TF、FF是网络图中标注时间参数,含义如下:ES = Earliest Start time(最早开始时间)。EF = Earliest Finish time(最早结束时间)。LS = Latest Start time(最晚开始时间)。LF = Latest Finish time(最晚结束时间)。TF = Total Float time(总浮动时间,总时差)...
Mamba在LSTF中扮演什么角色? LSTF是什么意思? 论文标题:TimeMachine: A Time Series is Worth 4 Mambas for Long-term Forecasting (这篇的标题应该是在模仿PatchTST的标题:A time series is worth 64 words: Long-term forecasting with transformers) 作者:Md Atik Ahamed, Qiang Cheng 机构:肯塔基大学(UKY)...
(LSTF) is the major problem. Some new models have been developed like transformers that show superior performance in capturing long-range time series data than RNN(recurrent neural networks) models. The transformer takes a lot ofGPUcomputing power, so using them on real-worldLSTFproblems is ...
长时间序列预测(Long Sequence Time-Series Forecasting,以下称为 LSTF)在现实世界中是比较基础但又十分重要的研究场景,例如商品销量及库存的预测、电力消耗的规划、股票价格、疾病传播与扩散等实际问题。然而LSTF因为其历史数据量大、计算复杂性高、预测精度要求高,一直以来并没有取得太好的效果。今年人工智能顶级大会...
Three 0.5% cold-leg small-break loss-of-coolant accident (SBLOCA) experi- ments were conducted at the ROSA-IV Large Scale Test Facility (LSTF) to in- vestigate the effects of break orientation on system thermal-hydraulic responses In these three experiments, the break hole was located at ...
