Complexity data science
“Complexity data science: A spin-off from digital twins “ Digital twins offer a new and exciting framework that has recently attracted significant interest in fields such as oncology, immunology, and cardiology. The basic idea of a digital twin is to combine simulation and learning to create a virtual model of a physical object. In this paper,…

Humans rationally balance abstract world models
This work adds to a growing body of research showing that the brain arbitrates between approximate decision strategies. The current study extends these ideas from simple habits into usage of more sophisticated approximate predictive models, and demonstrates that individuals dynamically adapt these in response to the predictability of their environment. How do people model the…

Defining intelligence: Bridging the gap
“Defining intelligence: Bridging the gap between human and artificial perspectives“ Proposes unified definitions for human and artificial intelligence. Distinguishes between artificial achievement/expertise and artificial intelligence. Advocates for AI metrics to ensure good quality AI system evaluations. Describes artificial general intelligence (AGI) mirroring human general intelligence. Evidence currently favours presence of artificial achievement over intelligence. Achieving…

Is Ockham’s razor losing its edge?
Is Ockham’s razor losing its edge? New perspectives on the principle of model parsimony The preference for simple explanations, known as the parsimony principle, has long guided the development of scientific theories, hypotheses, and models. Yet recent years have seen a number of successes in employing highly complex models for scientific inquiry (e.g., for 3D…

Bayesian Models of Cognition
“Bayesian Models of Cognition Reverse Engineering the Mind” is a new MIT-press Open Access book available for online reading. The definitive introduction to Bayesian cognitive science, written by pioneers of the field. How does human intelligence work, in engineering terms? How do our minds get so much from so little? Bayesian models of cognition provide…

regulation of motivated behavior
in “A unified theoretical framework underlying the regulation of motivated behavior“, Yu-Been Kim, Young Hee Lee, Shee-June Park and Hyung Jin Choi explain that multiple psychological components have evolved in order to orchestrate behaviors for survival. Despite several theories regarding behavior regulation, these theories do not clearly distinguish distinct components and do not explain the…

Why the simplest explanation isn’t always the best
Eva L. Dyer and Konrad Kording discuss in a commentary article “Why the simplest explanation isn’t always the best” an essential learning related to the article Phantom oscillations in principal component analysis (also available on BioRXiv) Dimensionality reduction simplifies high-dimensional data into a small number of representative patterns. One dimensionality reduction method, principal component analysis (PCA), often selects oscillatory…
