Unbalanced data in multiple object detection

Hello,

I am working in object detection with my own dataset.

The objects present in my dataset are very umbalanced, and I was wondering if it is possible to apply something as a weighted random sampler (I have already employed this for image classification) but for object detection.

In my images several structures are present.

Thankyou

Balancing a mutli-label dataset is a bit tricky, as a simple weighted sampling might even increase the imbalance, e.g. if the majority classes are often associated with the oversampled minority classes.

There are a few approaches, such as SCUMBLE, REMEDIAL, MLSOL, MLSMOTE etc.

I don’t know, what the current state of the art is, but I’m sure @rasbt would know. :wink:
