Avoiding bias in data collection ensures that your computer vision model performs well across various scenarios. To minimize bias, consider collecting data from diverse sources to capture different perspectives and scenarios. Ensure balanced representation among all relevant groups, such as different ages, genders, and ethnicities. Regularly review and update your dataset to identify and address any emerging biases. Techniques such as oversampling underrepresented classes, data augmentation, and fairness-aware algorithms can also help mitigate bias. By employing these strategies, you maintain a robust and fair dataset that enhances your model's generalization capability.
