Got negative values for predicted activities

[boaty]

Dear authur,

I used your demo run on my dataset, but the result made me confused, because i got negative predicted values. how is this possible.

the model applied is 'model_chembl_noFEPligands" in your actfound_demo. i also tried another models from your google drive check_points results folder, the results were pretty much the same.

is there some important parameters to better fit my data? thanks
