Single-label multi-classification or multi-label multi-classification?

[JingrongZheng]

I have read the paper and it seemed to be a single-label multi-classification problem. But the code use BCE and sigmoid instead of crossEntropy and softmax. So does it mean that the patient may have more than one lung disease?(I want to confirm it since I am not a medical expert)

It seemed that it is multi-labels multi-classfications. Sorry
