EXPLAINABLE MACHINE LEARNING FOR NETWORK INTRUSION DETECTION USING LIGHTGBM AND SHAP: AN IMPLEMENTATION STUDY ON HIKARI-2021

Machine-learning intrusion detection systems can provide strong predictive performance while offering limited evidence for why an individual network-flow record was classified as suspicious. This study examines the integration of SHapley Additive exPlanations (SHAP) with a LightGBM-based network intrusion detector trai...

INFLUENCE OF BIOREMEDIATION PARAMETERS ON TPH DEGRADATION AND MICROBIAL DYNAMICS IN CRUDE OIL-CONTAMINATED WATER TREATED WITH NATURAL BIOCARRIERS

Crude oil contamination of water poses serious environmental and public health risks due to its persistence and toxicity. This study evaluated the effectiveness of natural biocarriers, cassava mash (CM), maize bran (MB), and soursop peel (SP) in enhancing the bioremediation of crude-oil-polluted water using Aspergillus...

MIX DESIGN AND PROPORTIONAL REQUIREMENTS FOR THE PRODUCTION OF C30/37 INTERLOCKING CONCRETE TILES

The inadequate application of standard methods for the design and production of interlocking concrete tiles can result in poor-quality tiles and premature pavement failure. This study investigated suitable concrete mix proportions for producing interlocking concrete tiles with a target characteristic strength of 30 N/m...
