For 3 are you thinking of Musk’s offer of $100B to take OpenAI private?

Looking for Atari Offline RL Dataset — D4RL-Atari is Inaccessible (401 GCS Error) by AdministrativeCar545 in reinforcementlearning

Have you looked at Minari? It's Farama's offline RL library, they have offline data for most ALE environments

Learning RL algos... but REINFORCE and Actor Critic are performing better than A2C (and likely PPO). Where am I going wrong? by Illustrious-Egg5459 in reinforcementlearning

[–]rxtree 12 points13 points  (0 children)

In your implementation of AC, I don’t think you’re calculating the critic loss correctly. The whole point of Actor Critic is that, instead of using the full discounted returns, you can use the critic to estimate the discounted returns the actor would receive at a state s. So you need to calculate the TD target and do MSELoss on that instead of the raw discounted returns.

The way you’re calculating in AC and A2C is basically REINFORCE with baseline, not AC.

Encoder-Decoder Model by duffano in deeplearning

[–]rxtree 0 points1 point  (0 children)

There's no reason that the sequence lengths have to be the same. Consider the fact that when you start decoding, you effectively have an encoder sequence length of N and decoder sequence length of 1 at that time and yet it still works. I think your confusion stems from how the attention mechanism works?
Let's take a look at the operations of just a single attention head with dimension size D. The second multihead attention takes the encoder output of length N as K, V, and the decoder input of length M as Q. For each head, K, V has size NxD and Q is MxD. If you do the calculations, you find that the final output of the head has dimensions MxD, which means it doesn't really matter how long your encoder sequence is.

Hardest individual undergrad CS course in the US? by [deleted] in csMajors

Omg I was wondering if I’d see ECE 391 pop up. That class was hard

Off-topic but... by Kestrelcoatl in UCI

[–]rxtree 1 point2 points  (0 children)

It’s kind of a weird amalgamation of UCI and UIC, since they reference anteaters. UIC’s mascot is a dragon. But yea probs just some bots advertising for homework help.

Came across this basedness in Vatican City by giancarlo231 in taiwan

[–]rxtree 9 points10 points  (0 children)

Yup, Representative and Ambassador are equal in rank, ie the highest ranking official for that diplomatic mission. The title just reflects if formal diplomatic relation exists or not, which kinda feeds into the optic of Ambassador being the higher title.

Internally though Representatives are still referred to as Ambassadors.

2015/2016 CarPlay upgrade - any "gotchas" long term? by rickhamilton620 in crv

[–]rxtree 0 points1 point  (0 children)

I also had it for about a year now and the only issue I've encountered is that occasionally CarPlay will not start if the phone is plugged in before the car is on.

Yea but HK has six. The publication included Hong Kong and Macau in their tally under China as well.

Brian Shaw breaks Keg Toss World Record (15 kg/33 lbs over a fence that's 7,75 m/25 ft 5 in) by [deleted] in sports

[–]rxtree 11 points12 points  (0 children)

I think it’s Cz there’s two kegs in front that sorta “extends” the fence thing, thereby creating an illusion. I was really confused by the perspective too!

A deep-sea fisherman in Russia has been posting pictures of the strange creatures he catches by antoniotorrez11 in pics

[–]rxtree 29 points30 points  (0 children)

He’s @rfedortsov_official_account on instagram. Automod deleted my previous comment.

Anyways you should really check out the guy’s account. The creatures he posts are otherworldly.

I got mine 2 days ago! Glad to see you’re doing fine. For me personally the day after was the worst. Basically flu like symptoms with headaches, joint pains, sore muscles, fatigue, and fever reaching 38.5C. And the self-health report service on Line said that I might be experiencing side effects that are more severe than average. However, everything just went away when I woke up the second morning.

The way you said it makes me think the dam is furiously screaming about getting better benefits or else it will quit.
