The study proposes an improved Random Forest (RF) algorithm based on hierarchical clustering (HCRF). HCRF optimizes feature selection by establishing similar feature groups based on the GINI index and selecting features proportionally to construct a feature subset. This process reduces the impact of useless and redundant features, improving the model's generalization ability and overall performance. The HCRF algorithm showed significant improvements in all evaluation indicators, making it superior to other classifiers.

The modern power system is increasingly relying on solar photovoltaic power plants (PV PPs) to replace conventional synchronous generators. However, these plants lack natural rotational inertia, leading to frequency instability. To address this, the researchers limit PV PP pe*******on and provide virtual inertia from energy storage systems. They also propose a strategy to optimize the Fast Frequency Response (FFR) capacity of deloaded PV PPs using the Particle Swarm Optimization algorithm.

This article explores reducing grounding resistance in dry lands, specifically in acidic swamps. It uses a cost-effective dolomite mixture to address high soil resistivity. The study found that dolomite can generally overcome grounding resistance in acidic swamps, but the decrease was inconsistent due to changes in dolomite composition and rod electrode material. The method offers a range of resistance prices.

This paper presents a flexible design of patch antenna arrays (PAA) to address bandwidth limitations in the 2.4 GHz Industrial, Scientific, and Medical (ISM) band. The authors designed and evaluated 1x2, 2x2, and 2x4-element rectangular PAAs using a quarter-wave transformer method and a parallel scheme for connecting patches. They used FR-4 epoxy as the substrate material and conducted extensive simulations using Ansys HFSS. The 2x4 PAA had excellent performance metrics, including a gain of 9.17 dB, directivity of 13 dB, and a voltage standing wave ratio below 0.5.

Securing DNS over HTTPS traffic: a real-time analysis tool
DOI: https://doi.org/10.11591/csit.v5i3.p227-234

A study developed a live tool to analyze DNS over HTTPS (DoH) traffic and classify it as benign or malicious. Using machine learning algorithms like K-NN, RF, DT, DNN, and SVM, the tool achieved exceptional performance. It integrates with the Mallory tool for local DNS resolution, allowing for more accurate simulation of DoH queries. The tool's effectiveness in network security and threat detection is confirmed.

Adversarial attacks in signature verification: a deep learning approach
DOI: https://doi.org/10.11591/csit.v5i3.p215-226

This study develops a handwritten signature verification system using a convolutional neural network (CNN) and hand-crafted adversarial attacks. The model achieved a testing accuracy of 91.35% and a robust validation accuracy of nearly 98%. However, the model's accuracy is reduced to nearly 80% when manually constructed adversarial assaults are introduced. The study emphasizes the need for considering adversarial resilience in deep learning models for classification tasks.
