直观地说,OLS通过扩展观测集(并保持特征数量不变)而远离这一点。 Table 3 Average RMSE from 1000 simulation runs for the forecasting task, 48 vs. 60, 72 and 96 training observations 对于post-lasso,基于60、72和96个观测的结果与基于48个观测的结果非常相似。样本内和样本外的RMSE都没有明显变化。与OLS...

For the more curious data scientist, machine learning for demand forecasting also has stable accuracy / bias trade-offs that can be adjusted on an ’efficient frontier’ of data science workflow, so that an accurate ML forecasting solution can be implemented quickly, and then studied over time ...
In this paper we survey the most recent advances in supervised machine learning and high-dimensional models for time series forecasting. We consider both linear and nonlinear alternatives. Among the linear methods we pay special attention to penalized regressions and ensemble of models. The nonlinear ...
Forecasting involves predicting future spending by analyzing historical spending and evaluating future plans. The Tanzu CloudHealth Forecasting feature powered by machine learning (ML) allows forecasting costs from the current month up to the next 36 months (about 3 years) with the ability to choose ...
在全球经济加速变革的背景下,企业如何准确预测自身绩效已成为管理者日益关注的核心议题。近日,由汉口学院教授陈兴博士独自撰写的英文学术专著《MACHINE LEARNING MODEL FOR CORPORATE PERFORMANCE FORECASTING》(ISBN 979-11-988609-4-1)获得韩国人文社会科学研究院(KIHSS)选定,并正式面向海内外公开出版发行。
Forecasting sales is a common and essential use of machine learning (ML). Sales forecasts can be used to identify benchmarks and determine incremental impacts of new initiatives, plan resources in…
Moreover, the literature on time-series backcasting is also insufficient relative to forecasting in general. Thus, the predictive power of machine learning models for backcasting past time-series values is also imperative. Moreover, in evaluating the performance of ML algorithms and traditional time-...

In short, the use of forecasting models (such as those based on machine learning algorithms) to reduce FW is a topic that is still in an early stage of development. There is a need for further studies on this topic, particularly with a focus on causal models that include more diverse var...
