This work promotes accessible AI use by focusing on recognition and classification of traditional Adinkra symbols. The study builds a new ADINKRA image dataset with 174,338 images across 62 symbol classes. A CNN classifier is designed using six convolutional layers and three fully connected layers, and transfer learning with pre-trained VGG and ResNet extracts features for classical models. Performance is evaluated via accuracy and convergence, with visualization of influential prediction regions, forming a baseline for future dataset assessment.","ADINKRA SYMBOL RECOGNITION USING CLASSICAL MACHINE  \nLEARNING AND DEEP LEARNING  \narXiv :2311 . 15728v1 [ cs .CV] 27 Nov 2023  \n Michael Adjeisah  \nNational Centre for Computer Animation Bournemouth University Poole, BH12 5BB, United Kingdom [madjeisah@bournemouth.ac.uk](madjeisah@bournemouth.ac.uk)  \n Kwame Omono Asamoah  \nZhejiang Normal University Jinhua, 321004, Zhejiang, China [koasamoah2014@gmail.com](koasamoah2014@gmail.com)  \nMartha Asamoah Yeboah  \nCollege of Computer Science and Technology Zhejiang Normal University  \nJinhua, Zhejiang, 321004 China  \n[may138@zjnu.edu.cn](may138@zjnu.edu.cn)  \n Raji Rafiu King  \nProvincial Key Laboratory of Electronic, Functional Materials and Devices  \nHuizhou University  \nHuizhou City, 516001, Guangdong Province, China [mrkingraji@outlook.com](mrkingraji@outlook.com)  \n Godwin Ferguson Achaab  \nCollege of Computer Science and Technology Zhejiang Normal University Jinhua, Zhejiang, 321004 China [achaabf@gmail.com](achaabf@gmail.com)  \nKingsley Adjei  \nCollege of Computer Science and Technology Zhejiang Normal University Jinhua, Zhejiang, 321004 China[sleyadjei@gmail.com](sleyadjei@gmail.com)  \nABSTRACT  \nArtificial intelligence (AI) has emerged as a transformative influence, engendering paradigm shifts in global societies, spanning academia and industry. However, in light of these rapid advances, addressing the underrepresentation of black communities and African countries in AI is crucial. Boosting enthusiasm for AI can be effectively accomplished by showcasing straightforward applications around tasks like identifying and categorizing traditional symbols, such as Adinkra symbols, or familiar objects within the community. In this research endeavor, we dived into classical machine learning and harnessed the power of deep learning models to tackle the intricate task of classifying and recognizing Adinkra symbols. The idea led to a newly constructed ADINKRA dataset comprising 174,338 images meticulously organized into 62 distinct classes, each representing a singular and emblematic symbol. We constructed a CNN model for classification and recognition using six convolutional layers, three fully connected (FC) layers, and optional dropout regularization. The model is a simpler and smaller version of VGG, with fewer layers, smaller channel sizes, and a fixed kernel size. Additionally, we tap into the transfer learning capabilities provided by pre-trained models like VGG and ResNet. These models assist us in both classifying images and extracting features that can be used with classical machine learning models. We assess the model’s performance by measuring its accuracy and convergence rate and visualizing the areas that significantly influence its predictions. These evaluations serve as a foundational benchmark for future assessments of the ADINKRA dataset. We hope this application exemplar inspires ideas on the various uses of AI in organizing our traditional and modern lives.  \nA PREPRINT  \nKeywords Adinkra symbols · Convolutional neural network · Image classification · Machine learning · Transfer learning  \n1 Introduction  \nAI’s potential for innovation and advancement is undeniable [1], with applications ranging from healthcare [2, 3, 4, 5] and transportation [6, 7] to finance [8, 9] and education [10, 11, 12] . Nevertheless, in these swift developments, it is imperative to prioritize rectifying the inadequate representation of black communities and African nations within AI. The lack of representation raises concerns about the potential bias and limitations that may arise from predominantly homogeneous perspectives, hindering the realization of AI’s full potential and the equitable distribution of its benefits. To comprehensively address this issue, it is necessary to approach it from research areas like Natural Language Processing (NLP) [13] and Computer Vision (CV) [14, 15] perspectives, as they entail the
