Avsnitt

  • In this episode, Gianluca and Jared discuss the neurobiology of predictive processing, the role of dopamine in reward signalling, satisfaction, and human desire. They also touch on the relation of reward to reinforcement learning and artificial intelligence.

    The podcast then shifts to discuss the clinical manifestations of the predictive brain, including the computational psychiatry of depression, autism-spectrum-disorder, and schizophrenia, and how top-down prediction, and precision-weighted prediction error explain central aspects of these conditions.

  • This week’s episode of Bit of a Tangent is a continuation of our 3 part series on Predictive Processing - a fascinating neuroscientific account of the way our brains come to understand the world. If you haven’t already listened to part 1 (episode 028), check that out first!

    In this episode Gianluca and Jared discuss the importance of sensory precision, the circular causality of prediction and action, how action comes about in a counterintuitive way from high confidence predictions, the way in which prior expectations can bias sensory sampling, and how this could lead to self-fulfilling spirals that would make your life either much worse or much better!

  • It's here. It's finally here! The first in a series of three episodes diving into the predictive processing theory of brain function! Jared and Gianluca discuss top-down versus bottom-up perception, Bayesian Brain hypotheses, the logic of caring only about prediction error, and the phenomenology of visual illusions!

  • Gianluca and Jared have survived 2020 (so far) and are back for Season 3 of Bit of a Tangent. In this episode they bring you 7 new habits and techniques that can be used to iteratively upgrade yourself — even in lockdown. Forget everything else that’s going on in the world, and take a deep dive into personal optimisation. Or, as they’d put it, prepare to geek out on organisation hacks, bootstrapped learning, and motivation pumps.

    Jared and Gianluca exchange rapid-fire questions whilst becoming increasingly inebriated. Think of this episode as the Ferriss/Rose “Random Show,” but with more references to Bayesian inference. It’s pretty likely to entertain you, but hopefully you’ll find it interesting too. Topics include Email response times, VR projects, and the statistical approach to an ethical diet.

  • On this episode of Bit of A Tangent, we discuss the emerging field of self-supervised machine learning. This is an immensely exciting area of active research in machine learning and AI - one which most people haven’t even heard about yet! We build up to the intuition for the topic by covering supervised and unsupervised learning; autoencoders and dimensionality reduction, and exploring how these techniques could be applied to Gianluca’s Quantified Self n=1 sleep quality dataset. We culminate in a detailed discussion of the state-of-the-art Contrastive Predictive Coding model, and how it allows us to learn about the structure of the world, without tonnes of labelled training data!

  • This is part 3 of the series on Mental Models, in which Gianluca and Jared discuss the cognitive biases that often impede aspiring rationalists. They discuss the idea of “System 1 and 2” thinking as a framing for the entire discussion, before exploring 12 of the most deadly thinking traps and how to avoid them. This includes everything from the Planning Fallacy and Anchoring, to more esoteric pitfalls that are yet to be named. Finally, they describe meta-biases—like the Bias Blindspot and the Fallacy Fallacy—equipping your mental toolkit with everything you need to upgrade your thinking.

  • This is part 2 of our series on Mental Models. In it, we’re bringing you the most useful and applicable models we’ve encountered in everything we’ve read, heard or seen over the years! In part 2 we unpack models from Bayesian reasoning, calibration, and expected value. We also cover fat-tailed distributions, counterfactual reasoning, inversion, and red-teaming. Throughout, we build up each model with examples and motivations, and often found ourselves making previously unseen (by us) links to other models which gave us several new insights. We hope this conversation will do the same for you!

Bronwyn is a futurist and trend analyst with a background in marketing and economics. Gianluca and Jared pick her brain about the economic viability of UBI, the influence of politics and big tech, and the trends in automation that will shape the future of humanity. Regardless of your fiscal intuitions or political leanings, this episode will equip you with the core arguments in the UBI debate and leave you with plenty of food for thought.

    Bayesian Conspiracy (with David Spearman) on the economics of UBI vs. NIT: http://www.thebayesianconspiracy.com/2019/07/88-ubi-and-other-forms-of-evil-taxes/

  • This is part 2 of our series on free will! In this episode we reconcile how it is that we can feel like we have free will (even when we don’t), give an evolutionary argument for why this might be the case and show how knowing this makes us more compassionate people who are (paradoxically) better at achieving our goals. Along the way, we explain what a Bayesian Network is (and why you should care about yours), and give an introduction to some of the key ideas and concepts in the field of Reinforcement Learning (a subfield of AI) and how we can use these concepts to clarify our view of ourselves and the world!

  • This is Part 1 of the series on Free Will. In this episode, Gianluca and Jared dispel the assumption that humans have Free Will by presenting the argument from Determinism—popularised by Sam Harris. They discuss the evidence from physics, neurology, and the famous Libet experiments; before laying the groundwork for later conversations about what this implies morally and societally. You have no choice but to listen.

  • Jared and Gianluca try something new on this episode! We read passages from Robert Pirsig’s wonderful novel Zen and the Art of Motorcycle Maintenance, reacting and discussing as we go! Along the way, we explored the limits of conceptual understanding (a.k.a. Shut up and taste the wine!), how the words we use to describe reality also end up defining it, limiting it or expanding it, and why cliches are so easy to dismiss and when they shouldn’t be (hint: your gran was right - there’s nothing a good night’s sleep won’t solve). We also discuss what it means to truly understand something, and how our intuitive sense of what is excellent can guide us to cook great food, write beautiful code, and be delightful people!

    As a bonus, we drop some hints about an exciting upcoming episode, and at the end we each share the advice we’ve heard that has the highest impact with the fewest words!

  • We’ve all heard about the importance of learning. We’ve all heard about the importance of learning how to learn. Well, on this episode Gianluca and Jared dive into both of these topics. They discuss the philosophies of learning they’ve encountered on their own journeys, and share several key tricks that they’ve found most helpful over the years! Along the way they discovered a new way to think about how to keep your knowledge up to date in an ever changing world!

  • This is a discussion about why deep neural nets are unreasonably effective. Gianluca and Jared examine the relationships between neural architectures and the laws of physics that govern our Universe—exploring brains, human language, and linear functions. Nothing could have prepared them for the territories this episode expanded to, so strap yourself in!

    We also discuss the difference between attention and awareness and how can help you live a more engaged life, a simple rule of thumb to know when you’re using your time on earth well, and a quick trick to train your mind to dive straight into deep focus when you need to!

    Lastly, we discuss how we’ve set up our personal devices to get the most out of them while minimising distractions and as a bonus this episode we mention two other podcasts we’re loving at the moment!
