The computational power of the human brain
Peter J. Gebicke-Haerter published a great review article with this title. I selected some snippets and the key conclusion: At the end of the 20th century, analog systems in computer science have been widely replaced by digital systems due to their higher computing power. Nevertheless, the question keeps being intriguing until now: is the brain…

Humor – Filosofie
“Een kleine filosofie van de humor” door de Zwitserse filosoof Yves Bossart neemt ons mee op een even reis door de wereld van de humor. Volgens Ludwig Wittgenstein is humor geen stemming, maar een heuse levenshouding. Humor ontregelt én stelt ons in staat om enige afstand te nemen en zaken ter discussie te stellen. Umberto Eco…

Harris Hawks Optimization
The Harris hawk optimizer is a recent population-based metaheuristics algorithm that simulates the hunting behavior of hawks. This swarm-based optimizer performs the optimization procedure using a novel way of exploration and exploitation and the multiphases of search. A review research focuses on the applications and developments of the recent well-established robust optimizer Harris hawk optimizer…

Wicked7 – looking for “Regenerative” solution
12 jul 2022, TedX@Athens. Christian Sarkar makes bold statements: Globalization has failed. Income inequality has exploded. COVID hasn’t disappeared yet. And War is at the gate. What can be done in your neighborhood, in your city? We learn the lessons of regeneration from Palermo, Sicily – and the (website and) book by Christian Sarkar, Philip…

What If – Causal Inference (free)
Miguel Hernán made a revision of book “Causal Inference: What If” is available for download. The book provides a cohesive presentation of concepts of, and methods for, causal inference. Much of this material is currently scattered across journals in several disciplines or confined to technical articles. The authors expect that the book will be of…

A top-down, bottom-up model of circuit function for anxiety and depression.
A great review article describes the bottom-up and top-down processing from Marr’s computational-algorithmic-implementation perspective to understand depressive and anxious disease states. The review illustrate examples of bottom-up processing as basolateral amygdala signaling and projections and top-down processing as medial prefrontal cortex internal signaling and projections. Understanding these internal processing dynamics can help us better model…

“Fitness” Beats “Truth”
The “Fitness-Beats-Truth Theorem” provides a quantitative measure of the extent to which the fitness-only strategy dominates the truth strategy, and of how this dominance increases with the size of the perceptual space. The FBT Theorem supports the Interface Theory of Perception. The Interface Theory of Perception is discussed and described in detail in 2015 by…

Walking in nature is probably the highest ROI activity I have in my life.
Feeling stuck? Go for a walk. There is no mental block strong enough to outlast the power of a 30-minute walk. It’s a fact that some of your most creative moments come during periods of boredom. • On a walk • In the shower • Driving in silence • At dinner by yourself You’re bored,…

The Physics of Survival
Please enjoy the fascinating discussion of the free energy principle with Dr. Maxwell Ramstead, a leading thinker exploring the intersection of math, physics, and philosophy and Director of Research at VERSES. The 2 hour discussion includes great details on FEP. The FEP was proposed by renowned neuroscientist Karl Friston, this principle offers a unifying theory…

Complexity, Entropy & the Physics of Information
The specter of information is haunting sciences. With these words, Wojciech H. Zurek invited fellow scientists to attend the 1989 Santa Fe Institute workshop on which this proceedings volume is based. Thermodynamics, statistical mechanics, the quantum theory of measurement, the physics of computation, dynamical systems, molecular biology, and computer science — information remains central to the…

AI can distort human beliefs
Without a zone of uncertainty plus other troubling features, generative AI is poised to amplify bias and falsehoods, distort human perception. Individual humans form their beliefs by sampling a small subset of the available data in the world. Once those beliefs are formed with high certainty, they can become stubborn to revise. Fabrication and bias…

The IDEA (Internal Dominance over External Attention )
Sam Verschooren and Tobias Egner published “ When the mind’s eye prevails: “The Internal Dominance over ExternalAttention (IDEA) hypothesis“. The IDEA hypothesis asserts, contrary to the traditional view of attention as being primarily externally oriented, that attention is inherently biased toward internal information. Mine inner sense predominates in such a way over my five senses…

The self is an illusion
The truth is that your left brain has been interpreting reality for you your whole life, and if you are like most people, you have never understood the full implications of this. This is because we mistake the story of who we think we are for who we truly are. “Why are you unhappy?Because 99.9 percent of…

I must admit … meditative walking is, indeed, a practice.
The next time you feel stuck or have a problem you can’t solve, I encourage you to try a productive meditation. Occupy yourself with a routine activity and contemplate a well-defined problem, with the precise goal of finding a solution. The change of pace allows you to access big-picture thinking, a chance to mentally step…

Facts are not enough
Claude Garcia & Patrick Waeber developed a framework based on behavioural and cognitive sciences, game theory, and set theory that helps us understand decisionmaking in the context of uncertainty. It was published recently in a nice article on the researchfeatures of researchoutreach. Every single day we make thousands of decisions. Even if it is unclear…

Decoding reward–curiosity conflict in decision-making from irrational behaviors
Humans and animals are not always rational. “Decoding reward–curiosity conflict in decision-making from irrational behaviors” discusses the fact humans not only rationally exploit rewards but also explore an environment owing to their curiosity. However, the mechanism of such curiosity-driven irrational behavior is largely unknown. The article develops a decision-making model for a two choice task…
