The 21-year-old Yorkshireman said: "It was a tight match, some long rallies. I'm just disappointed to lose. I know what I could have done better, I just wasn't able to problem-solve during the match.
"I didn't quite finish the points when I needed to on some short balls and some bad unforced errors in key moments."
Edmund will now head to Cincinnati for the final Masters tournament before the US Open later this month.
He will take positive memories with him, saying: "It was my first Olympics and you've got to enjoy it as much as possible. I'm disappointed I lost but I'll definitely walk away remembering the experience and the good times."
