Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | that tells you a lot about what's gonna be the case | https://karpathy.ai/lexicap/0010-large.html#00:18:02.560 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | in the future. | https://karpathy.ai/lexicap/0010-large.html#00:18:04.640 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | Because that's what it means to take a high level action. | https://karpathy.ai/lexicap/0010-large.html#00:18:05.480 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | I say okay, I decide I'm gonna navigate | https://karpathy.ai/lexicap/0010-large.html#00:18:09.400 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | to the gas station because I need to get gas for my car. | https://karpathy.ai/lexicap/0010-large.html#00:18:13.040 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | Well, that'll now take five minutes to get there. | https://karpathy.ai/lexicap/0010-large.html#00:18:15.480 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | But the fact that I get there, | https://karpathy.ai/lexicap/0010-large.html#00:18:17.880 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | I could already tell that from the high level action | https://karpathy.ai/lexicap/0010-large.html#00:18:19.280 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | I took much earlier. | https://karpathy.ai/lexicap/0010-large.html#00:18:22.320 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | That we had a very hard time getting success with. | https://karpathy.ai/lexicap/0010-large.html#00:18:24.480 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | Not saying it's a dead end necessarily, | https://karpathy.ai/lexicap/0010-large.html#00:18:28.440 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | but we had a lot of trouble getting that to work. | https://karpathy.ai/lexicap/0010-large.html#00:18:30.640 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | And then we started revisiting the notion | https://karpathy.ai/lexicap/0010-large.html#00:18:33.120 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | of what are we really trying to achieve? | https://karpathy.ai/lexicap/0010-large.html#00:18:34.720 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | What we're trying to achieve is not necessarily hierarchy | https://karpathy.ai/lexicap/0010-large.html#00:18:37.800 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | per se, but you could think about | https://karpathy.ai/lexicap/0010-large.html#00:18:40.680 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | what does hierarchy give us? | https://karpathy.ai/lexicap/0010-large.html#00:18:41.720 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | What we hope it would give us is better credit assignment. | https://karpathy.ai/lexicap/0010-large.html#00:18:44.280 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | What is better credit assignment? | https://karpathy.ai/lexicap/0010-large.html#00:18:49.120 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | It's giving us, it gives us faster learning, right? | https://karpathy.ai/lexicap/0010-large.html#00:18:51.240 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | And so faster learning is ultimately maybe what we're after. | https://karpathy.ai/lexicap/0010-large.html#00:18:55.760 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | And so that's where we ended up with the RL squared paper | https://karpathy.ai/lexicap/0010-large.html#00:18:59.800 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | on learning to reinforcement learn, | https://karpathy.ai/lexicap/0010-large.html#00:19:03.400 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | which at a time Rocky Dwan led. | https://karpathy.ai/lexicap/0010-large.html#00:19:06.040 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | And that's exactly the meta learning approach | https://karpathy.ai/lexicap/0010-large.html#00:19:08.840 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | where you say, okay, we don't know how to design hierarchy. | https://karpathy.ai/lexicap/0010-large.html#00:19:11.080 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | We know what we want to get from it. | https://karpathy.ai/lexicap/0010-large.html#00:19:14.240 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | Let's just enter and optimize for what we want to get | https://karpathy.ai/lexicap/0010-large.html#00:19:15.760 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | from it and see if it might emerge. | https://karpathy.ai/lexicap/0010-large.html#00:19:18.240 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | And we saw things emerge. | https://karpathy.ai/lexicap/0010-large.html#00:19:20.200 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | The maze navigation had consistent motion down hallways, | https://karpathy.ai/lexicap/0010-large.html#00:19:21.240 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | which is what you want. | https://karpathy.ai/lexicap/0010-large.html#00:19:26.120 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | A hierarchical control should say, | https://karpathy.ai/lexicap/0010-large.html#00:19:27.160 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | I want to go down this hallway. | https://karpathy.ai/lexicap/0010-large.html#00:19:28.320 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | And then when there is an option to take a turn, | https://karpathy.ai/lexicap/0010-large.html#00:19:29.720 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | I can decide whether to take a turn or not and repeat. | https://karpathy.ai/lexicap/0010-large.html#00:19:31.640 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | Even had the notion of where have you been before or not | https://karpathy.ai/lexicap/0010-large.html#00:19:33.840 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | to not revisit places you've been before. | https://karpathy.ai/lexicap/0010-large.html#00:19:37.280 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | It still didn't scale yet | https://karpathy.ai/lexicap/0010-large.html#00:19:39.960 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | to the real world kind of scenarios I think you had in mind, | https://karpathy.ai/lexicap/0010-large.html#00:19:42.520 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | but it was some sign of life | https://karpathy.ai/lexicap/0010-large.html#00:19:46.000 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | that maybe you can meta learn these hierarchical concepts. | https://karpathy.ai/lexicap/0010-large.html#00:19:47.200 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | I mean, it seems like through these meta learning concepts, | https://karpathy.ai/lexicap/0010-large.html#00:19:51.160 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | get at the, what I think is one of the hardest | https://karpathy.ai/lexicap/0010-large.html#00:19:56.160 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | and most important problems of AI, | https://karpathy.ai/lexicap/0010-large.html#00:19:59.800 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | which is transfer learning. | https://karpathy.ai/lexicap/0010-large.html#00:20:02.360 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | So it's generalization. | https://karpathy.ai/lexicap/0010-large.html#00:20:04.040 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | How far along this journey | https://karpathy.ai/lexicap/0010-large.html#00:20:06.280 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | towards building general systems are we? | https://karpathy.ai/lexicap/0010-large.html#00:20:08.480 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | Being able to do transfer learning well. | https://karpathy.ai/lexicap/0010-large.html#00:20:11.160 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | So there's some signs that you can generalize a little bit, | https://karpathy.ai/lexicap/0010-large.html#00:20:13.600 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | but do you think we're on the right path | https://karpathy.ai/lexicap/0010-large.html#00:20:17.520 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | or it's totally different breakthroughs are needed | https://karpathy.ai/lexicap/0010-large.html#00:20:19.600 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | to be able to transfer knowledge | https://karpathy.ai/lexicap/0010-large.html#00:20:23.760 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | between different learned models? | https://karpathy.ai/lexicap/0010-large.html#00:20:26.800 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | Yeah, I'm pretty torn on this in that | https://karpathy.ai/lexicap/0010-large.html#00:20:31.240 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | I think there are some very impressive. | https://karpathy.ai/lexicap/0010-large.html#00:20:33.840 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | Well, there's just some very impressive results already. | https://karpathy.ai/lexicap/0010-large.html#00:20:35.560 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | I mean, I would say when, | https://karpathy.ai/lexicap/0010-large.html#00:20:40.520 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | even with the initial kind of big breakthrough in 2012 | https://karpathy.ai/lexicap/0010-large.html#00:20:44.040 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | with AlexNet, the initial thing is okay, great. | https://karpathy.ai/lexicap/0010-large.html#00:20:47.240 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | This does better on ImageNet, hence image recognition. | https://karpathy.ai/lexicap/0010-large.html#00:20:52.160 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | But then immediately thereafter, | https://karpathy.ai/lexicap/0010-large.html#00:20:55.680 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | there was of course the notion that, | https://karpathy.ai/lexicap/0010-large.html#00:20:57.840 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | wow, what was learned on ImageNet | https://karpathy.ai/lexicap/0010-large.html#00:21:00.520 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | and you now wanna solve a new task, | https://karpathy.ai/lexicap/0010-large.html#00:21:03.320 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | you can fine tune AlexNet for new tasks. | https://karpathy.ai/lexicap/0010-large.html#00:21:05.000 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | And that was often found to be the even bigger deal | https://karpathy.ai/lexicap/0010-large.html#00:21:09.080 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | that you learn something that was reusable, | https://karpathy.ai/lexicap/0010-large.html#00:21:12.040 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | which was not often the case before. | https://karpathy.ai/lexicap/0010-large.html#00:21:14.320 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | Usually machine learning, you learn something | https://karpathy.ai/lexicap/0010-large.html#00:21:16.040 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | for one scenario and that was it. | https://karpathy.ai/lexicap/0010-large.html#00:21:17.520 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | And that's really exciting. | https://karpathy.ai/lexicap/0010-large.html#00:21:19.320 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | I mean, that's a huge application. | https://karpathy.ai/lexicap/0010-large.html#00:21:20.280 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | That's probably the biggest success | https://karpathy.ai/lexicap/0010-large.html#00:21:22.280 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | of transfer learning today in terms of scope and impact. | https://karpathy.ai/lexicap/0010-large.html#00:21:23.680 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | That was a huge breakthrough. | https://karpathy.ai/lexicap/0010-large.html#00:21:27.920 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | And then recently, I feel like similar kind of, | https://karpathy.ai/lexicap/0010-large.html#00:21:29.040 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | by scaling things up, it seems like | https://karpathy.ai/lexicap/0010-large.html#00:21:33.040 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | this has been expanded upon. | https://karpathy.ai/lexicap/0010-large.html#00:21:34.760 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | Like people training even bigger networks, | https://karpathy.ai/lexicap/0010-large.html#00:21:36.160 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | they might transfer even better. | https://karpathy.ai/lexicap/0010-large.html#00:21:37.960 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | If you looked at, for example, | https://karpathy.ai/lexicap/0010-large.html#00:21:39.480 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | some of the OpenAI results on language models | https://karpathy.ai/lexicap/0010-large.html#00:21:41.200 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | and some of the recent Google results on language models, | https://karpathy.ai/lexicap/0010-large.html#00:21:43.400 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | they're learned for just prediction | https://karpathy.ai/lexicap/0010-large.html#00:21:47.560 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | and then they get reused for other tasks. | https://karpathy.ai/lexicap/0010-large.html#00:21:51.040 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | And so I think there is something there | https://karpathy.ai/lexicap/0010-large.html#00:21:54.960 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | where somehow if you train a big enough model | https://karpathy.ai/lexicap/0010-large.html#00:21:56.680 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | on enough things, it seems to transfer | https://karpathy.ai/lexicap/0010-large.html#00:21:58.520 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | some deep mind results that I thought were very impressive, | https://karpathy.ai/lexicap/0010-large.html#00:22:01.360 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | the Unreal results, where it was learned to navigate mazes | https://karpathy.ai/lexicap/0010-large.html#00:22:03.600 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | in ways where it wasn't just doing reinforcement learning, | https://karpathy.ai/lexicap/0010-large.html#00:22:09.240 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | but it had other objectives it was optimizing for. | https://karpathy.ai/lexicap/0010-large.html#00:22:11.240 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | So I think there's a lot of interesting results already. | https://karpathy.ai/lexicap/0010-large.html#00:22:14.280 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | I think maybe where it's hard to wrap my head around this, | https://karpathy.ai/lexicap/0010-large.html#00:22:17.240 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | to which extent or when do we call something generalization? | https://karpathy.ai/lexicap/0010-large.html#00:22:22.520 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | Or the levels of generalization in the real world, | https://karpathy.ai/lexicap/0010-large.html#00:22:26.720 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | or the levels of generalization involved | https://karpathy.ai/lexicap/0010-large.html#00:22:29.760 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | in these different tasks, right? | https://karpathy.ai/lexicap/0010-large.html#00:22:31.880 |
