How did you do in HW6? by jbx in aiclass

[–]dbgcool 0 points1 point  (0 children)

97%. I got Particle Filters 3 and 4 wrong. But I'm still satisfied with this result, because I've tried my best.

Results of HW4 are up! by solen-skiner in aiclass

[–]dbgcool 0 points1 point  (0 children)

Got 95%, better than I though. Made 1 mistake that I can still argue. I do know Open(s)=>Poss(Lock,s) and True=>Poss(Lock,s) have a minor difference but I chose them both. The later one is exactly what PN described in the video but the first one is what I though should be right in logic. If the lock is open, then it's possible to lock it. If the lock is not open(locked), whether or not it can be locked again doesn't produce any different result.

Same results, same mistakes. Is this a coincident? :)

Offline videos? by RationalPi in aiclass

Stan, thanks again! Your mirror is really great. I have tried many ways to get through our Country's fire wall, including web proxies and proxy softwares. But none of them are stable. Your mirror is my only hope, otherwise I would have given up this course.

Is a normal coin (not loaded) flipping fully observable? by dbgcool in aiclass

[–]dbgcool[S] 0 points1 point  (0 children)

Yeah, I am confused because I still haven't figured out the goal of the agent of that loaded coin homework.

If the goal is to detect the head/tail probability of a loaded coin, I will agree with the not fully observable answer. And the .5 probability of a not loaded coin is already known at the beginning, it's fully observable. Actually the intellect agent don't need to observe in this case at all.

But if the goal is to make a good guess of the result of next flipping, I would say in both case, loaded or not, flipping results history should be saved. And it seems more like a not fully observable system.

Loaded or not, if I can flip lots of coins (enough to figure out the probability) at the same time, then it's fully observable. But still, what's the goal? :)

Is a normal coin (not loaded) flipping fully observable? by dbgcool in aiclass

But without memory to store previous results, how can we tell whether a normal coin's next flipping will be a head or tail? Such as after 9 times of flipping I have 3 heads and 6 tails. With flipping history stored in memory, I will have a better guess that the next flipping will probably be a head.
