Lag-Llama: Towards Foundation Models for Time Series Forecasting 论文链接:arxiv.org/pdf/2310.0827 旨在建立时间序列预测的基础模型并研究其缩放行为,我们在此介绍我们正在进行的工作——Lag-Llama。这是一个通用的单变量概率时间序列预测模型,它是在大量时间序列数据的基础上训练的。该模型在未见过的“分布外”时...
Autoregressive Integrated Moving Average (ARIMA) models have long been the go-to method for time series forecasting. Renowned for their ability to capture complex patterns in data, they’ve become an essential tool for data scientists and statisticians alike. But to use them effectively requires a ...
NLinear (Zeng et al., 2023) 对时间序列进行归一化并使用线性层进行预测。 DLinear(Zeng 等人,2023)遵循 Autoformer 并使用季节性趋势分解。 最近,扩散模型也被开发用于时间序列数据 TimeGrad(Rasul 等人,2021)是一种条件扩散模型,它以自回归方式进行预测,降噪过程由循环神经网络的隐藏状态引导。然而,由于使用自...
The importance of statistical forecasting is in its ability to discover hidden knowledge from databases. In this paper, forecasting is implemented in the BSE indices, three time series algorithms are used, namely-simple moving average forecasting, weighted average forecasting and exponential smoothing ...
Lag-Llama: Towards Foundation Models for Time Series Forecasting 论文摘要:该论文提出构建基于时间序列的基础模型,并研究其在不同规模下的行为。论文介绍了 Lag-Llama 模型,它是一个通用的单变量概率时间序列预测模型,通过在大量时间序列数据上进行训练来展示其在未见过的“分布外”时间序列数据集上的预测能力,优于...
Time series forecasting occurs when you make scientific predictions based on historical time stamped data. It involves building models through historical analysis and using them to make observations and drive future strategic decision-making. An important distinction in forecasting is that at the time ...
1.Time-LLM: Time Series Forecasting by Reprogramming Large Language Models 通过重新编程大型语言模型进行时间序列预测 简述:Time-LLM是一种重新编程大型语言模型(LLM)以进行通用时间序列预测的方法,通过将输入的时间序列与文本原型重新编程并使用Prompt-as-Prefix(PaP)来增强LLM对时间序列数据的推理能力。
