Tracking technical change: Past, present and future
Canadian Journal of Economics/Revue canadienne d'économique, Volume 57, Issue 4, Page 1047-1087, November/Novembre 2024.Abstract Productivity growth in many countries has remained low for several years. Whether new technologies can reverse the trend depends on the scope of their impact and scale of their adoption—two dimensions of technical change that are historically difficult to measure.

Regulation of reinforcement learning parameters captures long‐term changes in rat behaviour
European Journal of Neuroscience, Volume 60, Issue 4, Page 4469-4490, August 2024.In a three‐armed bandit task conducted over several sessions, rats show improved performance and decreased exploration, which cannot be captured by a Q‐learning model with static parameters. Meta‐learning models in which the average reward rate regulates either the exploration‐exploitation trade‐off or the rate of learning captures these long‐term ...

European Journal of Neuroscience, Volume 59, Issue 7, Page 1657-1680, April 2024.The experimental results from numerous stimulation studies in the monkey basal ganglia are combined so as to identify the possible transmission delays in the basal ganglia circuitry. These delays are then injected into an existing computational model of the monkey basal ganglia, revealing that simulating dopaminergic depletion at extrastriatal sites ...

Ecology and Evolution, Volume 14, Issue 3, March 2024.Our research harnesses cutting‐edge technologies, including remote underwater stereo‐video and AI‐driven multi‐object tracking, to measure functional traits and the rates of energy expenditure of key grazing fish species on coral reefs. By doing so, we uncover the substantial influence of species like the Brown surgeonfish and Yellowtail tang on ...

Somatosensory Loss Influences the Adoption of Self-Centered Versus Decentered Perspectives
Frontiers in Psychology, 2019 The body and the self are commonly experienced as forming a unity. Experiencing the external world as distinct from the self and the body strongly relies on adopting a single self-centered perspective which results in integrating multisensory sensations ...

Algorithms, 2020 Understanding the behaviors and intentions of humans is still one of the main challenges for vehicle autonomy. More specifically, inferring the intentions and actions of vulnerable actors, namely pedestrians, in complex situations such as urban traffic ...

International Journal of Advanced Robotic Systems, 2016 In this article, we present a simple agent which learns an internal representation of space without a priori knowledge of its environment, body, or sensors. The learned environment is seen as an internal space representation.

Indirect genetic effects allow escape from the inefficient equilibrium in a coordination game
Evolution Letters, 2020 Social interactions involving coordination between individuals are subject to an “evolutionary trap.” Once a suboptimal strategy has evolved, mutants playing an alternative strategy are counterselected because they fail to coordinate with the majority ...
