Abstract

Cyberbullying has emerged as a persistent social issue in tandem with the rapid proliferation of social media usage, particularly in developing nations such as Indonesia. Online bullying extends beyond explicit insults to encompass more nuanced forms, including denigration and social exclusion, which are often subtle and context-dependent. This diversity presents significant challenges for automated detection systems, especially when cyberbullying is treated as a single, homogeneous category. To address this challenge, this study proposes a two-stage classification framework for detecting cyberbullying in the Indonesian language using the IndoBERT model. In the first stage, a binary classification model is employed to differentiate between bullying and non-bullying content. In the second stage, cyberbullying tweets are further categorized into three specific types: harassment, denigration, and exclusion. The model is trained using a curated dataset of Indonesian tweets collected from publicly available social media content. The results indicate that the proposed framework achieves strong and consistent performance, particularly in fine-grained cyberbullying classification, with an overall accuracy of approximately 92% in the second stage. These findings suggest that hierarchical classification can yield robust performance and effectively aid in the detection of cyberbullying.

Abstract

Early diagnosis of autism spectrum disorder (ASD) plays a crucial role in facilitating prompt interventions and assessing post-therapy progress, both of which can greatly improve developmental trajectories. The emergence of artificial intelligence—particularly deep learning—has opened new possibilities for clinicians to detect ASD with improved precision and speed. This study investigates the utilization of deep learning models to recognize ASD among 13-year-old children based on eye movement data collected as participants observed static images and short video sequences. The dataset included visual and numerical variables, such as gaze position and pupil diameter, allowing for a multimodal analytical approach. For the numerical dataset, a multilayer perceptron (MLP) neural network produced the best outcomes, yielding an accuracy of 91.7% and a recall rate of 83.3% in ASD classification. Meanwhile, the Vision Transformer (ViT) model performed best for image-based analysis, reaching an accuracy of 78.2% and a recall rate of 88.6%. Overall, the findings highlight the potential of deep learning frameworks as objective, data-driven tools for ASD detection in both clinical and research contexts.Key words: Autism, Computer Vision, Deep Learning Model, Vision Transformer.
