About confusion matrix

[springGUOHUO]

Hello, thank you for your open source project. I'm still a student studying. The dataset I currently use is ansim (tut sound events 2018 - ambisonic, anechoic and synthetic impulse response dataset). I want to make the confusion matrix of each classification. Where should I change it? thank you

I read your article and found that I can use classification methods for SED, but I found that only regression methods are supported in the code, can you help me please?
