Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | this linear controller here. | https://karpathy.ai/lexicap/0010-large.html#00:13:42.520 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | Neural network learns to tile the space | https://karpathy.ai/lexicap/0010-large.html#00:13:43.840 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | and say linear controller here, | https://karpathy.ai/lexicap/0010-large.html#00:13:45.640 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | another linear controller here, | https://karpathy.ai/lexicap/0010-large.html#00:13:46.600 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | but it's more subtle than that. | https://karpathy.ai/lexicap/0010-large.html#00:13:48.320 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | And so it's benefiting from this linear control aspect, | https://karpathy.ai/lexicap/0010-large.html#00:13:50.080 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | it's benefiting from the tiling, | https://karpathy.ai/lexicap/0010-large.html#00:13:52.000 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | but it's somehow tiling it one dimension at a time. | https://karpathy.ai/lexicap/0010-large.html#00:13:53.600 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | Because if let's say you have a two layer network, | https://karpathy.ai/lexicap/0010-large.html#00:13:57.440 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | if in that hidden layer, you make a transition | https://karpathy.ai/lexicap/0010-large.html#00:13:59.440 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | from active to inactive or the other way around, | https://karpathy.ai/lexicap/0010-large.html#00:14:03.360 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | that is essentially one axis, but not axis aligned, | https://karpathy.ai/lexicap/0010-large.html#00:14:06.560 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | but one direction that you change. | https://karpathy.ai/lexicap/0010-large.html#00:14:09.520 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | And so you have this kind of very gradual tiling | https://karpathy.ai/lexicap/0010-large.html#00:14:12.360 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | of the space where you have a lot of sharing | https://karpathy.ai/lexicap/0010-large.html#00:14:14.780 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | between the linear controllers that tile the space. | https://karpathy.ai/lexicap/0010-large.html#00:14:16.800 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | And that was always my intuition as to why | https://karpathy.ai/lexicap/0010-large.html#00:14:19.560 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | to expect that this might work pretty well. | https://karpathy.ai/lexicap/0010-large.html#00:14:21.720 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | It's essentially leveraging the fact | https://karpathy.ai/lexicap/0010-large.html#00:14:24.820 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | that linear feedback control is so good, | https://karpathy.ai/lexicap/0010-large.html#00:14:26.160 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | but of course not enough. | https://karpathy.ai/lexicap/0010-large.html#00:14:28.560 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | And this is a gradual tiling of the space | https://karpathy.ai/lexicap/0010-large.html#00:14:29.880 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | with linear feedback controls | https://karpathy.ai/lexicap/0010-large.html#00:14:31.800 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | that share a lot of expertise across them. | https://karpathy.ai/lexicap/0010-large.html#00:14:33.520 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | So that's really nice intuition, | https://karpathy.ai/lexicap/0010-large.html#00:14:36.620 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | but do you think that scales to the more | https://karpathy.ai/lexicap/0010-large.html#00:14:39.040 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | and more general problems of when you start going up | https://karpathy.ai/lexicap/0010-large.html#00:14:41.520 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | the number of dimensions when you start | https://karpathy.ai/lexicap/0010-large.html#00:14:44.720 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | going down in terms of how often | https://karpathy.ai/lexicap/0010-large.html#00:14:49.480 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | you get a clean reward signal? | https://karpathy.ai/lexicap/0010-large.html#00:14:52.760 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | Does that intuition carry forward to those crazier, | https://karpathy.ai/lexicap/0010-large.html#00:14:55.400 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | weirder worlds that we think of as the real world? | https://karpathy.ai/lexicap/0010-large.html#00:14:58.800 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | So I think where things get really tricky | https://karpathy.ai/lexicap/0010-large.html#00:15:03.360 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | in the real world compared to the things | https://karpathy.ai/lexicap/0010-large.html#00:15:08.040 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | we've looked at so far with great success | https://karpathy.ai/lexicap/0010-large.html#00:15:09.760 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | in reinforcement learning is the time scales, | https://karpathy.ai/lexicap/0010-large.html#00:15:11.920 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | which takes us to an extreme. | https://karpathy.ai/lexicap/0010-large.html#00:15:17.320 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | So when you think about the real world, | https://karpathy.ai/lexicap/0010-large.html#00:15:18.960 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | I mean, I don't know, maybe some student | https://karpathy.ai/lexicap/0010-large.html#00:15:21.800 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | decided to do a PhD here, right? | https://karpathy.ai/lexicap/0010-large.html#00:15:24.320 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | Okay, that's a decision. | https://karpathy.ai/lexicap/0010-large.html#00:15:26.920 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | That's a very high level decision. | https://karpathy.ai/lexicap/0010-large.html#00:15:28.760 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | But if you think about their lives, | https://karpathy.ai/lexicap/0010-large.html#00:15:30.840 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | I mean, any person's life, | https://karpathy.ai/lexicap/0010-large.html#00:15:32.680 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | it's a sequence of muscle fiber contractions | https://karpathy.ai/lexicap/0010-large.html#00:15:34.080 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | and relaxations, and that's how you interact with the world. | https://karpathy.ai/lexicap/0010-large.html#00:15:37.440 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | And that's a very high frequency control thing, | https://karpathy.ai/lexicap/0010-large.html#00:15:40.360 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | but it's ultimately what you do | https://karpathy.ai/lexicap/0010-large.html#00:15:42.800 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | and how you affect the world, | https://karpathy.ai/lexicap/0010-large.html#00:15:44.640 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | until I guess we have brain readings | https://karpathy.ai/lexicap/0010-large.html#00:15:46.600 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | and you can maybe do it slightly differently. | https://karpathy.ai/lexicap/0010-large.html#00:15:48.320 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | But typically that's how you affect the world. | https://karpathy.ai/lexicap/0010-large.html#00:15:49.800 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | And the decision of doing a PhD is so abstract | https://karpathy.ai/lexicap/0010-large.html#00:15:52.600 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | relative to what you're actually doing in the world. | https://karpathy.ai/lexicap/0010-large.html#00:15:56.360 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | And I think that's where credit assignment | https://karpathy.ai/lexicap/0010-large.html#00:15:59.320 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | becomes just completely beyond | https://karpathy.ai/lexicap/0010-large.html#00:16:01.120 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | what any current RL algorithm can do. | https://karpathy.ai/lexicap/0010-large.html#00:16:04.800 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | And we need hierarchical reasoning | https://karpathy.ai/lexicap/0010-large.html#00:16:06.760 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | at a level that is just not available at all yet. | https://karpathy.ai/lexicap/0010-large.html#00:16:09.000 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | Where do you think we can pick up hierarchical reasoning? | https://karpathy.ai/lexicap/0010-large.html#00:16:12.520 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | By which mechanisms? | https://karpathy.ai/lexicap/0010-large.html#00:16:14.920 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | Yeah, so maybe let me highlight | https://karpathy.ai/lexicap/0010-large.html#00:16:16.960 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | what I think the limitations are | https://karpathy.ai/lexicap/0010-large.html#00:16:18.680 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | of what already was done 20, 30 years ago. | https://karpathy.ai/lexicap/0010-large.html#00:16:20.640 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | In fact, you'll find reasoning systems | https://karpathy.ai/lexicap/0010-large.html#00:16:26.080 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | that reason over relatively long horizons, | https://karpathy.ai/lexicap/0010-large.html#00:16:27.720 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | but the problem is that they were not grounded | https://karpathy.ai/lexicap/0010-large.html#00:16:30.960 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | in the real world. | https://karpathy.ai/lexicap/0010-large.html#00:16:32.800 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | So people would have to hand design | https://karpathy.ai/lexicap/0010-large.html#00:16:34.200 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | some kind of logical, dynamical descriptions of the world | https://karpathy.ai/lexicap/0010-large.html#00:16:39.160 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | and that didn't tie into perception. | https://karpathy.ai/lexicap/0010-large.html#00:16:43.920 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | And so it didn't tie into real objects and so forth. | https://karpathy.ai/lexicap/0010-large.html#00:16:46.360 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | And so that was a big gap. | https://karpathy.ai/lexicap/0010-large.html#00:16:49.280 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | Now with deep learning, we start having the ability | https://karpathy.ai/lexicap/0010-large.html#00:16:51.120 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | to really see with sensors, process that | https://karpathy.ai/lexicap/0010-large.html#00:16:53.960 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | and understand what's in the world. | https://karpathy.ai/lexicap/0010-large.html#00:16:59.560 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | And so it's a good time to try | https://karpathy.ai/lexicap/0010-large.html#00:17:01.440 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | to bring these things together. | https://karpathy.ai/lexicap/0010-large.html#00:17:02.840 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | I see a few ways of getting there. | https://karpathy.ai/lexicap/0010-large.html#00:17:04.960 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | One way to get there would be to say | https://karpathy.ai/lexicap/0010-large.html#00:17:06.480 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | deep learning can get bolted on somehow | https://karpathy.ai/lexicap/0010-large.html#00:17:08.160 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | to some of these more traditional approaches. | https://karpathy.ai/lexicap/0010-large.html#00:17:10.120 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | Now bolted on would probably mean | https://karpathy.ai/lexicap/0010-large.html#00:17:12.280 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | you need to do some kind of end to end training | https://karpathy.ai/lexicap/0010-large.html#00:17:14.120 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | where you say my deep learning processing | https://karpathy.ai/lexicap/0010-large.html#00:17:16.320 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | somehow leads to a representation | https://karpathy.ai/lexicap/0010-large.html#00:17:18.600 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | that in term uses some kind of traditional | https://karpathy.ai/lexicap/0010-large.html#00:17:20.840 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | underlying dynamical systems that can be used for planning. | https://karpathy.ai/lexicap/0010-large.html#00:17:24.640 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | And that's, for example, the direction Aviv Tamar | https://karpathy.ai/lexicap/0010-large.html#00:17:29.840 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | and Thanard Kuretach here have been pushing | https://karpathy.ai/lexicap/0010-large.html#00:17:32.280 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | with causal info again and of course other people too. | https://karpathy.ai/lexicap/0010-large.html#00:17:34.080 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | That's one way. | https://karpathy.ai/lexicap/0010-large.html#00:17:36.720 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | Can we somehow force it into the form factor | https://karpathy.ai/lexicap/0010-large.html#00:17:38.200 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | that is amenable to reasoning? | https://karpathy.ai/lexicap/0010-large.html#00:17:41.080 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | Another direction we've been thinking about | https://karpathy.ai/lexicap/0010-large.html#00:17:43.760 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | for a long time and didn't make any progress on | https://karpathy.ai/lexicap/0010-large.html#00:17:46.520 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | was more information theoretic approaches. | https://karpathy.ai/lexicap/0010-large.html#00:17:50.200 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | So the idea there was that what it means | https://karpathy.ai/lexicap/0010-large.html#00:17:53.640 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | to take high level action is to take | https://karpathy.ai/lexicap/0010-large.html#00:17:56.560 |
Pieter Abbeel: Deep Reinforcement Learning | Lex Fridman Podcast #10 | and choose a latent variable now | https://karpathy.ai/lexicap/0010-large.html#00:17:59.960 |
