Algorithmic bias in facial recognition technology has emerged as a significant concern since it consistently misidentifies certain races and genders, leading to undesirable outcomes. To investigate how facial recognition systems work and the potential factors that affect misidentification, I worked on a project titled Celebrity Facial Recognition with two fellow students. The project was designed to verify whether our machine learning models accurately identify and detect the correct person from a particular group of people with similarities in their appearances. By utilizing the Convolutional Neural Network (CNN) for image classification, web scraping and web crawling for data collection of six different groups (White male, White female, Black male, Black female, Asian male, and Asian female), and the PyTorch framework for transfer learning, we developed the project to train and evaluate the models. Once images were gathered from a search engine, the models were trained using input data and processed through multiple layers to detect the correct subject. The project resulted in the models detecting the correct person with about 80% validation accuracy across all six groups, but lower validation accuracy among them occurred within the White male and Asian male groups. Future work on the project could include expansion of high-quality datasets and different configurations for equitable performance across diverse populations.
