confusion matrix - backgroud part

[Swimlim]

I just put on my data which is 'wacho', 'soil', 'norma'. but there is background part.
What is the Background mean? and How to remove the background part?
and How can the matrix data value be better?

@Swimlim background is inherent in object detection, every anchor either detects background or your classes. To improve your matrix results see Tips for Best Training Results below.
