In the object detection task, the goal (target) is information about the position and class of objects in the image. Usually, this is a set of annotations that include:
- Coordinates of bounding boxes, for example in the format (x, y, width, height) or (x_min, y_min, x_max, y_max).
- Object classes corresponding to each box.
The loss function in detection typically combines several components:
- Localization loss — measures the error in predicting the coordinates of the boxes (e.g., Smooth L1 loss).
- Classification loss — evaluates the accuracy of predicting the object class (e.g., cross-entropy).
- Sometimes additional components are added, such as for confidence estimation (confidence loss).
The total loss function is a weighted sum of these components, which is optimized during model training to better predict both the location and class of objects.
