    #7 Tony Zador: The Embodied Turing Test, Genomic Bottlenecks, Molecular Connectomics

    Tony has a lab at Cold Spring Harbour, New York. Using rodents, his lab studies the neural circuits underlying auditory decisions. He is also developing new technologies for connectome sequencing and does some NeuroAI work. In the episode, after a detour on language and the Costa Rican singing mouse, we discuss his recent paper on 'The Embodied Turing Test' and Moravec's paradox; the idea that what we find hard is easy for AI, and vice versa. We explore how Tony's work in creating a rodent decision-making model might inform a virtual platform for embodied animal-like agents. Evolution is an underlying thread in the discussion, including his work on the genomic bottleneck, which might 'be a feature, not a bug'.  We discuss how Tony is revolutionizing connectomics using molecular sequencing and why people in AI should care about connectomics and architecture more generally. Finally, we discuss some cultural questions as to why some people might believe more or less in 'Human uniqueness' vs evolutionary continuity and some career questions.  Timestamps: (00:00) - Intro (02:08) - Tony's background, Costa Rican singing mouse (06:59) - Traditional & embodied Turing Test, large language models (15:16) - Mouse intelligence, evolution, modularity, dish-washing dogs?

    #6 Alex Lascarides: Linguistics from Frege to Settlers of Catan

    Alex is a professor and the director of the Institution for Language, Cognition and Computation at Edinburgh. She is interested in discourse coherence, gestures, complex games and interactive task learning. After we find out about Alex's background and geek out over Ludwig Wittgenstein, she tells us about Dynamic Semantics and Segmented Discourse Representation Theory (SDRT). SDRT considers discourse as actions that change the state space of the world and requires agents to infer coherence in the discourse. Then, I initiate a discussion between Felix Hill and Alex by asking her about her opinion on compositionality and playing a clip where Felix gives his "spicy take" on theoretical linguistics. Next, we talk about gestures and how they could be analysed using logic or a deep learning classifier. Then, we talk about non-linguistic events and the conceptualization problem. Later, we discuss Alex's work on Settlers of Catan, and how this links to deep reinforcement learning, Monte Carlo tree search, and neurosymbolic AI. Next, we briefly bring up game theory and then talk about interactive task learning, which is about agents learning and adapting in unknown domains. Finally, there are some career questions on whether to do a PhD and what makes a good supervisee & supervisor. Timestamps: (00:00) - Intro (02:00) - Alex's background & Wittgenstein geekiness (05:15) - Discourse Coherence & Semantic Discourse Representation Theory (SDRT) (12:56) - Compositionality, Responding to Felix Hill's "spicy take" (23:50) - Analysing gestures with logic and deep learning (38:54) - Pointing and evolution (42:28) - Non-linguistics events in Settlers of Catan, conceptualization problem (54:15) - 3D simulations and supermarket stocktaking (59:19) - Settlers of Catan, Monte Carlo tree search, neurosymbolic AI (01:11:08) - Persuasion & Game Theory (01:17:23) - Interactive Task Learning, symbol grounding, unknown domain (01:25:28) - Career advice Alex Webpage (All articles are open access) My Twitter Talks and Papers Talk on Discourse Coherence and Segmented Discourse Representation Theory A Formal Semantic Analysis of Gesture paper with Matthew Stone paper A formal semantics for situated conversation paper with Julie Hunter & Nicholas Asher paper Game strategies for The Settlers of Catan paper with Markus Guhe paper Evaluating Persuasion Strategies and Deep Reinforcement Learning methods for Negotiation Dialogue agents paper with Simon Keizer , Markus Guhe, & Oliver Lemon paper Learning Language Games through Interaction paper with Sida Wang, Percy Liang, Christopher Manning paper Interactive Task Learning Paper with Mattias Appelgren paper Follow the podcast For new episode releases, follow me on Twitter.

    #5 Felix Hill: Grounded Language, Transformers, and DeepMind

    Felix is a research scientist at DeepMind. He is interested in grounded language understanding and natural language processing (NLP). After finding out about Felix's background, we bring up compositionality and explore why natural language is NonCompositional (also, the name of Felix's blog). Then, Felix tells us a bit about his work in Cambridge on abstract vs concrete concepts and gives us a quick crash course on the role of recurrent neural networks (RNNs), long short-term memory (LSTMs), and transformers in language models. Next, we talk about Jeff Elman's landmark paper 'Finding Structure in Time' and how neural networks can learn to understand analogies. After, we discuss the core of Felix work: Training language agents in 3D simulations, where we raise some questions on language learning as an embodied agent in space and time, and Allan Paivio's dual coding theory implemented in the memory of a language model. Next, we stick with the theme of memory retrieval and discuss Felix and Andrew Lampinen's work on 'mental time travel' in language models. Finally, I ask Felix on some good strategies on how to get into DeepMind and the best way to learn NLP. Timestamps: (00:00) - Intro (07:57) - Compositionality in natural language (16:42) - Abstract vs concrete concepts (24:03) - RNNs, LSTMs, Transformers (34:12) - Prediction, time and Jeff Elman (48:04) - Neural networks & analogies (56:32) - Grounded language, 3D simulations, babies, (01:05:20) - Keeping vision and language data separate (01:13:51) - NeuroAI and mental time travel (01:21:47) - Getting into DeepMind and learning NLP Felix Website (good overview for his papers) Papers Abstract vs concrete concepts paper Jeff Elman (1990): Finding structure in time paper Analogies paper Dual coding theory paper Mental Time Travel paper My Twitter My LinkedIn

    #4 Beren Millidge: Reinforcement Learning through Active Inference

    Beren is a postdoc in Oxford with a background in machine learning and computational neuroscience. He is interested in Active Inference (related to the Free Energy Principle) and how the cortex can perform long-term credit assignment as deep artificial neural networks do. We start off with some shorter questions on the Free Energy Principle and its background concepts. Next, we get onto the exploration vs exploitation dilemma in reinforcement learning and Beren's strategy on how to maximize expected reward from restaurant visits - it's a long episode :=). We also discuss multimodal representations, shallow minima, autism, and enactivism. Then, we explore predictive coding going all the way from the phenomenon of visual fading, to 20-eyed reinforcement learning agents and the 'Anti-Grandmother Cell'. Finally, we discuss some open questions about backpropagation and the role of time in the brain, and finish the episode with some career advice about writing, publishing, and Beren's future projects!

    #3 Mark Sprevak: 4E, The Chinese Room Argument, Predictive Coding

    Mark is a philosopher of computation and cognitive science at Edinburgh. We start off the conversation exploring why we shouldn't attribute computation to stones and talk about instances of distributed cognition in classical antiquity. Then, we discuss the relationship between functionalism and extended cognition with the paradigmatic example of Otto's notebook and some implications for deep learning researchers. Next off is the famous Chinese Room Argument and how the 'Robot Reply' illustrates the need for embodiment when going from 'cat' syntax to cat semantics. After a quick rendezvous with the frame problem (see also Ep1), Hubert Dreyfus and Heideggerian AI, we move onto predictive coding, David Marr's three levels of analysis and the idea of representation in the brain. We finish off the conversation with some very good reading strategies and why we should all move to Edinburgh. Timestamps: (00:00) - Intro (03:04) - Does a stone do computation? (08:16) - Distributed cognition in classical antiquity (20:27) - Functionalism and extended cognition (33:00) - Chinese Room Argument & Robot Reply (45:51) - Frame Problem, Hubert Dreyfus (56:47) - David Marr's Three Levels, Predictive Coding and Representation in the Brain (01:16:14) - Career advice & Why Edinburgh is the best Mark's Website (All of Mark's publications are freely available there) My Twitter Papers Clark and Chalmers 1998 paper - The Extended Mind Ballard et al. 1997 paper - Off-loading information onto the environment Rao and Ballard 1999 paper - Predictive Coding Spratling 2008 paper - Predictive Coding

    #2 Barbara Webb: Insect Robotics

    Barbara is a professor of Biorobotics at Edinburgh. We start with a quick philosophical exploration of robots using chairs, James Gibson's concept 'affordances', and whether insects have meaning. Next, we talk about how robots can be used to test hypotheses in biology. For most of the episode, we discuss the incredible things crickets, ants and the mushroom body can do. We explore some interesting questions such as: How does embodiment in crickets replace the need for neural processing? How do ants integrate different sensory modalities? Do insects have consciousness? And can we find associative general-purpose brain regions in the insect brain? We also discuss how her robotics work can inform predictive coding and reinforcement learning. As usual, we finish off with a career question and her future projects. Timestamps: (00:00) - Intro (02:43) - Philosophy questions (08:11) - Robot models to test biological hypotheses (17:45) - Cricket bodies, cricket robots, and cricket music (26:58) - Ants, spatial navigation, visual memory (30:14) - Insect learning, sparse coding, insect consciousness (39:25) - Lessons for embodied AI, predictive coding (43:57) - Reinforcement learning paper (50:58) - Career advice (56:57) - Upcoming project GRASP, postdoc positions Barbara's website Talks and papers by Barbara : Talk on ants, other insects: Talk on n crickets 7 dimensions for robot models paper Reinforcement Learning paper Multimodal sensory integration in insects paper Postdoc at Edinburgh Insect AI InsectNeuroNano My Twitter

    #1 Ron Chrisley: Embodied AI, Non-Conceptual Content, AI Creativity

    In the first episode of the Embodied AI Podcast, Ron tells us about his journey from Stanford to machine learning and the people that inspired him to dig deeper on philosophical questions around embodiment. Ron lays out 4 dimensions to think about Embodied AI and situates its role in the history of AI - mainly the move away from Symbolic AI. We take a close look at his 2003 paper on Embodied Artificial Intelligence, making connections to the relevance problem, Lewis Carroll's What the Tortoise Said to Achilles, Ludwig Wittgenstein, and current matching learning. Ron also discusses his work on non-conceptual content and synthetic phenomenology, showing us how we can use embodied technologies to study non-systematic aspects of our experience or that of a robot. We finish off with his recent ideas about AI creativity and the future of Embodied AI, with some career advice for younger listeners.
