The metrics question

[ZztLn]

Hey there, I see f1score set threshold = 10，so I want to know the meaning of this. `def f1score(app_gt, app_pred): threshold = 10 gt_temp = np.array(app_gt) gt_temp = np.where(gt_temp<threshold,0,1) pred_temp = np.array(app_pred) pred_temp = np.where(pred_temp<threshold,0,1)

return f1_score(gt_temp, pred_temp)

`

Thank you ,very much!
