Energy cost of computation: stochastic thermodynamics?
“Is stochastic thermodynamics the key to understanding the energy costs of computation?” The relationship between the thermodynamic and computational properties of physical systems has been a major theoretical interest since at least the 19th century. It has also become of increasing practical importance over the last half-century as the energetic cost of digital devices has…

Communicate Unflattening
I already mentioned in a previous blog entry the “Krebs Cycle of Creativity“, a map that describes the perpetuation of creative energy, analogous to the Krebs Cycle proper. In this analogy of the Krebs Cycle, the four modalities of human creativity— Science, Engineering, Design and Art— replace the Krebs Cycle’s carbon compounds. Each of the modalities…

Functional Trade-offs in Cognition
“Basic Functional Trade-offs in Cognition: An Integrative Framework” by Marco Del Giudice and Bernard J. Crespi, 2018. Trade-offs between advantageous but conflicting properties (e.g., speed vs. accuracy) are ubiquitous in cognition, but the relevant literature is conceptually fragmented, scattered across disciplines, and has not been organized in a coherent framework. This paper takes an initial step toward a general…

Nature heals
“Nature heals: An informational entropy account of self-organization and change in field psychotherapy“Highlights This paper reviews biophysical models of psychotherapeutic change based on synergetics and the free energy principle. These models suggest that introducing sensory surprise into the patient-therapist system can lead to self-organization and the formation of new attractor states, disrupting entrenched patterns of…

Affect-centered account of motivated behavior
“The affective gradient hypothesis: an affect-centered account of motivated behavior“: everyone agrees that feelings and actions are intertwined, but cannot agree how. According to dominant models, actions are directed by estimates of value and these values shape or are shaped by affect. The article proposes instead that affect is the only form of value that…

KNOWLEDGE ACQUISITION hindered by KNOWLEDGE ENTROPY DECAY during language model pretraining
This paper describes how a model’s tendency to broadly integrate its parametric knowledge evolves throughout pretraining, and how this behavior affects overall performance, particularly in terms of knowledge acquisition and forgetting. The concept of knowledge entropy is introduced, which quantifies the range of memory sources the model engages with; high knowledge entropy indicates that the…
