Optimal ratio for data splitting
Statistical Analysis and Data Mining: The ASA Data Science Journal, 2022 AbstractIt is common to split a dataset into training and testing sets before fitting a statistical or machine learning model. However, there is no clear guidance on how much data should be used for training and testing. In this article, we show that the optimal training/testing splitting ratio is , where is the number of parameters in a linear ...

Exergy Analysis of Two-Stage Organic Rankine Cycle Power Generation System
Entropy, 2020 Organic Rankine cycle (ORC) power generation is an effective way to convert medium and low temperature heat into high-grade electricity. In this paper, the subcritical saturated organic Rankine cycle system with a heat source temperature of 100~150 °C is

Haplodiploidy and the Evolution of Eusociality: Split Sex Ratios [PDF]
The American Naturalist, 2012 It is generally accepted that from a theoretical perspective, haplodiploidy should facilitate the evolution of eusociality. However, the "haplodiploidy hypothesis" rests on theoretical arguments that were made before recent advances in our empirical understanding of sex allocation and the route by which eusociality evolved.

CES Transactions on Electrical Machines and Systems, 2019 The split ratio which is defined as the ratio between rotor and stator outer diameters is critical for permanent magnet (PM) machines. In this paper, the split ratio in small high speed PM machines is optimized analytically by considering both stator and

All-Dielectric Metasurface-Based Beam Splitter with Arbitrary Splitting Ratio [PDF]
Nanomaterials, 2021 The development of optical systems is heading to multi-branch circuit design and miniaturization. A beam splitter is a common device for dividing an incident beam into two separate beams. Conventional beam splitters are constructed using coated prisms or glass plate.

Variations on a theme: splitting ratio [PDF]
Anaesthesia, 1985 Summary An expression for the splitting ratio (bypass gas/gas through vaporizing compartment) is derived formally. The factors affecting volatile agent gaseous fraction and, more importantly, partial pressure are discussed in relation to changes in temperature and barometric pressure.

Dewatering of Kerosene using Hydrocyclone
Journal of Engineering, 2020 Water/oil emulsion is considered as the most refractory mixture to separate because of the interference of the two immiscible liquids, water and oil. This research presents a study of dewatering of water / kerosene emulsion using hydrocyclone.

Modulated-Splitting-Ratio Fiber-Optic Temperature Sensor [PDF]
SPIE Proceedings, 1989 A fiber-optic temperature sensor is described that uses a small silicon beamsplitter whose splitting ratio varies as a function of temperature. A four-beam technique is used to measure the sensor's temperature-indicating splitting ratio. This referencing method provides a measurement that is largely independent of the transmission properties of the ...
