添加一个阀值进行判断

可参考这篇：2022脑机接口算法挑战赛：脑纹识别(多任务版) https://aistudio.baidu.com/aistudio/projectdetail/4308574?channelType=0&channel=0

            preds = loaded_model(data)
            preds = self.softmax(preds)

            label = paddle.argmax(preds).numpy()[0]
            preds_ = preds.tolist()[0]
            ratio = preds_[label]
            if ratio < self.minRatio : # 小于阀值，表示为入侵者
                label = 0
            else:
                label = label + 1
            
            testLabel = df.loc[i,'SubjectID']
            if testLabel == 'None':
                label_ = label
            else:
                testLabel = int(testLabel.replace('sub',''))
                if testLabel == label:
                    label_ = 1
                else:
                    label_ = 0
