Abstract: Abstract Adolescent (or juvenile) delinquency is defined as the habitual engagement in unlawful behavior of a minor under the age of majority. According to studies, the likelihood of acquiring a deviant personality increases significantly during adolescence. As a result, identifying deviant youth early and providing proper medical counseling makes perfect sense. Due to the scarcity of qualified clinicians, human appraisal of individual adolescent behavior is subjective and time-consuming. As a result, a machine learning-based intelligent automated system for assessing and grading delinquency levels in teenagers at an early stage must be devised. To solve this problem, a soft voting-based ensemble classification model has been developed that includes a Decision Tree, Multi-layer Perceptron, and Support Vector Machine as base classifiers to accurately classify teenagers into three groups based on severity levels, viz., low, medium, and high. Over the normalized structured behavioral data, the proposed soft voting-based model outperforms all other individual classifiers with 87.50% accuracy, an AUC of 0.94, 0.81 Kappa value, and an F-score of 0.88.
