This post was made on the 8th of April and from the turn of events in the both the EPL and the UEFA champions league, the supercomputer got the predictions wrong. While we've seen how impactful Artificial Intelligence is in transforming various sectors of the economy, they also have their limitations. Prediction are guesses, AI picks random data and comes up with a result. Looking at the EPL take right now, it'll take a miracle for Liverpool to win the league, the outcome of the above mentioned leagues is a good reason why we shouldn't base our gambling predictions on AI.
I agree with you and indeed, even though everything is made as well as possible and the quality of artificial intelligence is well developed, there will always be failures in terms of predicting the results of a sports competition.
Accumulation will only be based on the performance of team at certain time, just like supercomputer or AI has an accumulation in predicting results that will only be based on the quality of the team when the artificial intelligence is working with is going on.
It is clear that Liverpool is predicted to have big chance of winning the Premier League title because at that time Liverpool performed very well and managed to top the standings and Manchester City is predicted to have a big chance of winning the UCL because they were champions and are still in good form.
But in reality everything failed, what was shown did not succeed in showing accurate results and if artificial intelligence was used again now then what would be shown would be much different from before.
I really surprised if anyone trusts artificial intelligence enough to predict the outcome of competition, it just temporary accumulation with no guarantee whatsoever.
