Mosaic augmentation influence on custom dataset

Question

I'm trying to train yolov5 on custom dataset with very similar classes: person in jacket / person in shirt. Due to nature of mosaic, sometimes only person's legs are visible on image - therefore we're unable to categorize person correctly (jacket / shirt).

Can I tweak it with some hyper params to achieve best results for my case?

@kbegiedza yes of course, you can modify all hyperparameters including mosaic probability in your hyp file: https://github.com/ultralytics/yolov5/blob/8aa196ce08007aa1033b0e42931c247e1e491321/data/hyps/hyp.scratch-low.yaml#L1-L34
