| Popis: | Many popular visual datasets used to train deep neural networks for computer vision applications, especially for facial analytics, are created by retrieving images from the internet. Search engines are often used to perform this task. However, due to localisation and personalisation of search results by the search engines along with the image indexing method used by these search engines, the resultant images overrepresent the demographics of the region from where they were queried from. As most of the visual datasets are created in western countries, they tend to have a western centric bias and when these datasets are used to train deep neural networks, they tend to inherit these biases. Researchers studying the issue of bias in visual datasets have focused on the racial aspect of these biases. We approach this from a geographical perspective. In this paper, we 1) study how linguistic variations in search queries and geographical variations in the querying region affect the social and cultural aspects of retrieved images focusing on facial analytics, 2) explore how geographical bias in image search and retrieval can cause racial, cultural and stereotypical bias in visual datasets and 3) propose methods to mitigate such biases. |
