Abstract

With the inherent complexity and variability of handwritten symbols, accurate recognition is crucial for various applications. This research aims to enhance the recognition of handwritten math symbols through a deep learning model named Convolutional Neural Network (CNN). In particular, the study utilizes a diverse dataset of approximately 370,000 images representing 82 math symbol categories, employing preprocessing and data augmentation techniques to enhance model performance. The implemented CNN model, built with TensorFlow, achieves an accuracy of 0.04. Comparative analysis with Random Forest, Support Vector Machine (SVM), and K-Nearest Neighbor categorization algorithm (KNN) demonstrates the CNN model's inferior performance in terms of accuracy, recall, and F1-scores. This highlights the need for further refinement and optimization of symbol recognition models. Future research should focus on larger and more diverse datasets, exploring different CNN architectures, and optimizing hyperparameters to improve classification accuracy. Despite its limitations, this study contributes to the field of handwritten math symbol recognition, emphasizing the importance of developing reliable and effective solutions for automated interpretation of mathematical expressions.
