What are the applications of focal loss in machine learning?
Focal loss is primarily used in tasks like object detection, especially in scenarios with class imbalance.
Can you explain how it helps with class imbalance?
Sure! Focal loss down-weights easy examples and focuses more on hard-to-classify instances, improving model performance.
Are there specific models that benefit from using focal loss?
Yes, models like RetinaNet for object detection and various deep learning architectures in image classification benefit significantly.
What are some alternatives to focal loss?
Alternatives include standard cross-entropy loss, weighted cross-entropy, and other loss functions designed for imbalanced data.
