Intermittent Time Series Demand Forecasting Using Dual Convolutional Neural Networks [PDF]

open access: yesMendel
Forecasting intermittent demands is challenging due to their irregular and unpredictable demand pattern. This makes the businesses unprepared for upcoming demands, where the conventional methods often fail to predict the demand occurrence pattern ...

Intermittent demand forecasts with neural networks [PDF]

open access: yes, 2013
Intermittent demand appears when demand events occur only sporadically. Typically such time series have few observations making intermittent demand forecasting challenging.

The effects of integrating management judgement into intermittent demand forecasts [PDF]

open access: yes, 2009
Empirical research suggests that quantitatively derived forecasts are very frequently judgementally adjusted. Nevertheless, little work has been conducted to evaluate the performance of these judgemental adjustments in a practical demand/sales context ...

Improving forecasting by estimating time series structural components across multiple frequencies [PDF]

open access: yes, 2014
Identifying the appropriate time series model to achieve good forecasting accuracy is a challenging task. We propose a novel algorithm that aims to mitigate the importance of model selection, while increasing accuracy.

Noninvasive ventilatory support to reverse weight loss in Duchenne muscular dystrophy: A case series

open access: yesPulmonology, 2019
This case series of five patients with Duchenne muscular dystrophy demonstrates the nutritional advantages of instituting noninvasive intermittent positive pressure ventilatory support via 15 mm angled mouthpieces to relieve tachypnea and provide more ...

Identification of arterial oxygen intermittency in oximetry data

open access: yesScientific Reports, 2022
In patients with kidney failure treated by hemodialysis, intradialytic arterial oxygen saturation (SaO2) time series present intermittent high-frequency high-amplitude oximetry patterns (IHHOP), which correlate with observed sleep-associated breathing ...

Effects of judo-specific intermittent training on lower-limb impulse and specific performance in judokas [PDF]

open access: yesPeerJ
Intermittent training (IT) has been shown to enhance athletic performance by improving aerobic and anaerobic capacities, neuromuscular efficiency, and recovery key factors for judokas given the intermittent nature of judo combat.

Investigating the Accuracy of Autoregressive Recurrent Networks Using Hierarchical Aggregation Structure-Based Data Partitioning

open access: yesBig Data and Cognitive Computing, 2023
Global models have been developed to tackle the challenge of forecasting sets of series that are related or share similarities, but they have not been developed for heterogeneous datasets.

Strategic planning of renewable distributed generation in radial distribution system using advanced MOPSO method

open access: yesEnergy Reports, 2020
The integration of wind turbine, solar photovoltaic based distributed generation in low voltage distribution network has many advantages. However, the output power from wind turbine and solar PVs are intermittent in nature.
