Mental models vs cell schemes [PDF]

open access: yesInvestigações em Ensino de Ciências, 2002
Student's mental representations of cell are examined from the perspectives of Johnson-Laird's mental models theory five years after instruction. The observed identity and stability of such representations are then interpreted under the framework of ...

COVID-19: Data-Driven Mean-Field-Type Game Perspective

open access: yesGames, 2020
In this article, a class of mean-field-type games with discrete-continuous state spaces is considered. We establish Bellman systems which provide sufficiency conditions for mean-field-type equilibria in state-and-mean-field-type feedback form.

Towards a Unified Theory of Learning and Information

open access: yesEntropy, 2020
In this paper, we introduce the notion of “learning capacity” for algorithms that learn from data, which is analogous to the Shannon channel capacity for communication systems.

Machine learned synthesizability predictions aided by density functional theory

open access: yesCommunications Materials, 2022
In data-driven approaches for materials discovery, it is essential to account for phase stability when predicting synthesizability. Here, by combining density functional theory calculations and machine learning, the authors predict the synthesizability ...

Design and Implementation of Novel LMI-Based Iterative Learning Robust Nonlinear Controller

open access: yesComplexity, 2021
An iterative learning robust fault-tolerant control algorithm is proposed for a class of uncertain discrete systems with repeated action with nonlinear and actuator faults. First, by defining an actuator fault coefficient matrix, we convert the iterative

An Actor-Critic Framework for Online Control With Environment Stability Guarantee

open access: yesIEEE Access, 2023
Online actor-critic reinforcement learning is concerned with training an agent on-the-fly via dynamic interaction with the environment. Due to the specifics of the application, it is not generally possible to perform long pre-training, as it is commonly ...

Evolving stochastic learning algorithm based on Tsallis entropic index [PDF]

open access: yes, 2005
In this paper, inspired from our previous algorithm, which was based on the theory of Tsallis statistical mechanics, we develop a new evolving stochastic learning algorithm for neural networks.
