Link must feel like a god after watching this

The bucketloads of cars pouring across the track will never not be comical

“Look what they need to mimic my power” - Link

The AI is incapable of taking one step back in order to potentially take two steps forward

You need to add mutations to get out of local maximums. It's the same concept as evolution, genes randomly mutates most of the time into something with no benefit. Every once in a while you get something with a huge advantage like another cone so you can distinguish between green and red. Give the AI random inputs at a range of different points and eventually one will stumble into something more optimal.

There’s something kind of cute about all these cars trying their best

5 hours till release is an unbearable amount of time to wait

Maybe next time you should try the epsilon greedy approach and the epsilon decay to like 0.5 or even 0.6 So the agent never stop finding new ways of doing things.

14:26 I mean damn just run it another week of training and see if it will do even better

Pre liking the video cause I've yet to see a disappointing video from this guy lol

An idea for a different way to reward the Ai:
Reward for time with wheels on the ground
Reward for Speed slide
Reward for uberbugs etc.


That way you reward it for exploring the Techniques the pros use when hunting a map

What seems to happen is that not the fastest AI gets to be built upon, but the fastest ai THAT FINISHES. Once they find a consistent line that gets them to the finish they try and improve upon that line, but it fails to consider different lines that could be faster and in the end you end up with the fastest line that finishes, not the fastest line that could've been. You could try and work with more checkpoints in specific locations. That or insert more randomness so it keeps experimenting with different lines. Cool video though, looking forward to the other videos :)

im not sure but i feel like you could get a better route by:

1. making the punishment for getting a bad run lower
2. reducing the reward for getting an average run
3. greatly increasing the reward for getting a really good run

This would punish the AI less for trying out new routes and it could get higher rewards if it finds a really good route once.

I'm not an expert with in artificial intelligence, but I’m an engineer with a high math level, and I would recommend increasing the reward substantially based on how quickly it reaches the finish line. I would recommend that you make it so the reward is 2^x or something along those lines

pure cinema, the way he makes the videos, the editinng, the storytelling and the way he explains hard things in an easy way. Its just special

Link went trough the middle of the 2 poles (11:21) you said Link is only doing 1 thing diff which was his approach angle but he also lands and drives through the middle of the pole and he gains 0.01 sec on the next check point but he stays on the left while the ai goes to the right for the long U-turn what if the Ai went through the middle of the poles and went on the left but swerved to the right before the big u-turn jump?

this is the reason why we on top of food chain. human are all human, but we are all not the same. HUMAN CREATED AI.

The fact that a literal AI didn't beat link after 2000 simulated hours is a true testament to how insanely good link is. Amazing video as always, excited to see what'll happen on the rest of the campaign.

On the last attempt to change the AI’s line, you blocked the line into the flip. That doesn’t necessarily encourage it to change how it approaches the flip, just where on the ramp it will be. If the AI is blocked from landing on the right side, it will have to adjust its line in some way to compensate, if it’s going to make it across. IOW, put the block in front of the landing zone, not the take-off zone.
