综述Review

The balancing trick: Optimized sampling of imbalanced datasets—A brief survey of the recent State of the Art

平衡技巧:不平衡数据集的优化采样-对最新技术的简要概述

Dr. Seba Susan PhD, Amitesh Kumar

This paper surveys recent sampling techniques addressing the class‐imbalance issue. The application of nature‐inspired evolutionary optimization techniques to intelligent sampling is examined and so are hybrid sampling strategies that select and retain the difficult‐to‐learn samples and discard the easy‐to‐learn samples. The findings by various researchers are summarized to a logical end, and various possibilities for the future are outlined.

Chinedu Matthew Agu, Matthew Chukwudi Menkiti, Paschal Enyinnaya Ohale, Victor Ifeanyi Ugonabo

The temperature, time, and particle size effects on Irvingia gabonensis kernel oil (IGKO) yield, as well as the kinetics and thermodynamics parameters, were investigated. The physicochemical properties of IGKO indicated that viscosity, acidity, dielectric strength, flash, and pour points were, , 25.83 kV, 285°C, and 17°C, respectively, suggesting its feasibility as transformer fluid upon further treatment. Between the pseudo second order (PSO) and hyperbolic kinetic models studied, the former best describes the experimental data.

Sebastian Babilon, Paul Myland, Lucas Schlestein, Julian Klabes, Tran Quoc Khanh

Knowledge of the exact tissue topology may support computer‐assisted or augmented‐reality‐guided microsurgical treatments and enables additional features such as spatially resolved spectral reconstruction of surface reflectances and subsequent automated tissue recognition. Thus, a new method for high‐resolution depth measurements in digital microsurgical applications to gain this knowledge based on the principle of laser triangulation is proposed in this work.

4. Energy efficient zonebased clustering algorithm using fuzzy inference system for wireless sensor networks

无线传感器网络中基于模糊推理系统的节能分区聚类算法

Annie Sujith, D. Ramya Dorai, V. N. Kamalesh

We propose an Energy‐Efficient Zone‐based Clustering algorithm for Wireless Sensor Network. The sensing field is divided into equal size zones; and one Zone Monitor is selected in each zone. The proposed approach uses Unequal Clustering in Sensing Field, Uniform Cluster Head Distribution in the zone, and Uniform Clustering at a zone level. In addition, re‐clustering happens at zone level, hence reducing the re‐clustering frequency. We compare the proposed algorithm with other approaches for three different network scenarios. The simulation results show that the proposed algorithm outperforms the other methods.

我们提出了一种基于区域的节能聚类算法,用于无线传感器网络。感应场被划分为相同大小的区域,并在每个区域中选择一个区域监控器。所提出的方法在检测场使用非均匀聚类,在区域内使用一致的簇头分布,并使用区域水平的一致聚类。此外,发生了区域水平的重新聚类,因此减少了重新聚类的频率。我们在三种不同的网络情况比较了所提出的算法与其他方法,仿真结果表明,本文所提出的算法优于其他方法。

伊朗通货膨胀率的年度预测:自回归综合移动平均值建模方法

Samrad Jafarian‐Namin, Seyyed Mohammad Taghi Fatemi Ghomi, Mohsen Shojaie, Saeed Shavvalpour

In Box‐Jenkins methodology, time series models are in fact autoregressive integrated moving average models, also known as ARIMA models in statistics. Using various metrics, different types of models have been studied to confirm their effectiveness. Finally, non‐seasonal ARIMA (1,0,0) is indicated to be the most appropriate model to forecast the yearly inflation rate.

在Box-Jenkins方法中,时间序列模型实际上是自回归综合移动平均模型,在统计学中也被称为ARIMA模型。使用各种指标,对不同类型的模型进行了研究以确认其有效性。最后,我们认为非季节性的ARIMA(1,0,0)是预测年度通货膨胀率的最合适模型。

8. Hot deformation characteristics and kinetics analysis for Nibased corrosion resistant alloy

镍基耐蚀合金的热变形特性和动力学分析

Lei Wang, Feng Liu, Hongyuan Chen, Qiang Chi

The hot deformation characteristics of Nickel‐based corrosion resistant alloy was studied in the temperature range of 1050° to 1200°C and the strain rate range of 0.001 to 0.1 s−1 by employing hot compression tests. Basing on the Avrami equation through using the critical strain (εc) and the strain for 50% DRX (ε0.5), a kinetic model for dynamic recrystallization (DRX) was established, where the model parameters could be obtained using the modified Zener‐Hollomon parameter (Z*). Furthermore, the relationship between em and ε0.5 is established. Finally, a power law relation between DRX grain size (Ddrx) and Z*, with an exponent of −0.36, was found.

通过热压试验,研究了镍基耐蚀合金在1 050到1 200°C的温度范围和0.001到0.1 s-1的应变速率范围内的热变形特性。在Avrami方程的基础上,通过使用临界应变(εc)和50%DRX的应变(ε0.5),建立了动态再结晶(DRX)的动力学模型,其中模型参数可以通过修改的Zener-Hollomon参数(Z*)获得。此外,还建立了em和ε0.5之间的关系。最后,发现了DRX晶粒尺寸(Ddrx)和Z*之间的幂律关系,其指数为-0.36。
