Compared to what?
"According to a paper published in Nature Communications today, the machine learning model achieved higher overall appreciation among trained panelists in blind tastings."
Higher appreciation than what? Did the panelists prefer machine-learned beers to uneducated ones? Did the model appreciate beer more than the panelists? (Were I one of the panelists, I might still appreciate beer after having been blinded, but I think I'd be a bit resentful.)
