Research on Attack Detection of Cyber Physical Systems Based on Improved Support Vector Machine

open access: yesMathematics, 2022
Cyber physical systems (CPS), in the event of a cyber attack, can have a serious impact on the operating physical equipment. In order to improve the attack detection capability of CPS, an support vector machine (SVM) attacks detection model based on ...

Iterative Metric Learning for Imbalance Data Classification [PDF]

open access: yesProceedings of the Twenty-Seventh International Joint Conference on Artificial Intelligence, 2018
In many classification applications, the amount of data from different categories usually vary significantly, such as software defect predication and medical diagnosis. Under such circumstances, it is essential to propose a proper method to solve the imbalance issue among the data.

A New Phase Classifier with an Optimized Feature Set in ML-Based Phase Prediction of High-Entropy Alloys

open access: yesApplied Sciences, 2023
The phases of high-entropy alloys (HEAs) are closely related to their properties. However, phase prediction bears a significant challenge due to the extensive search space and complex formation mechanisms of HEAs.

Data imbalance in CRISPR off-target prediction

open access: yesBriefings in Bioinformatics, 2019
Abstract For genome-wide CRISPR off-target cleavage sites (OTS) prediction, an important issue is data imbalance—the number of true OTS recognized by whole-genome off-target detection techniques is much smaller than that of all possible nucleotide mismatch loci, making the training of machine learning model very challenging.

An Efficient Improved Greedy Harris Hawks Optimizer and Its Application to Feature Selection

open access: yesEntropy, 2022
To overcome the lack of flexibility of Harris Hawks Optimization (HHO) in switching between exploration and exploitation, and the low efficiency of its exploitation phase, an efficient improved greedy Harris Hawks Optimizer (IGHHO) is proposed and ...

Budgetary and External Imbalances Relationship: A Panel Data Diagnostic [PDF]

open access: yesSSRN Electronic Journal, 2009
We assess the cointegration relationship between current account and budget balances, and effective real exchange rates, using recent bootstrap panel cointegration techniques and SUR methods. We investigate the magnitude of the relationship between the two imbalances for each country for the period 1970-2007, and for different EU and OECD country ...
