Model-Free Connectedness Measures

open access: yesSSRN Electronic Journal, 2023
This paper introduces a model-free connectedness approach by constraining the model-based connectedness approach of Diebold and Yilmaz (2012). By doing so, we demonstrate how the adoption of this benchmark model is relevant for statistical, theoretical ...

Model-free reinforcement learning with a non-linear reconstructor for closed-loop adaptive optics control with a pyramid wavefront sensor [PDF]

open access: yes, 2022
We present a model-free reinforcement learning (RL) predictive model with a supervised learning non-linear reconstructor for adaptive optics (AO) control with a pyramid wavefront sensor (P-WFS). First, we analyse the additional problems of training an RL

Complete model-free sliding mode control (CMFSMC)

open access: yes, 2021
This study presents a complete model-free sliding mode control (CMFSMC) framework for the control of continuous-time non-affine nonlinear dynamic systems with unknown models. The novelty lies in the introduction of two equalities to assign the derivative

A Synchronized Current Difference Updating Technique for Model-Free Predictive Current Control of PMSM Drives

open access: yesIEEE Access, 2021
Model-free predictive current control (MFPCC) is a promising substitute for model predictive current control (MPCC). However, the performance of the MFPCC, to a large extent, hinges on the update frequency of its lookup table.

Model-Free PI/PID Controller Tuning of Higher Order Nonlinear Dynamic Systems [PDF]

open access: yesModeling, Identification and Control, 2019
This paper concerns model-free PI/PID controller tuning of possible (nonlinear) higher order systems. The method can be considered as a three-step procedure.

Model-Free Guidance Method for Drones in Complex Environments Using Direct Policy Exploration and Optimization

open access: yesDrones, 2023
In the past few decades, drones have become lighter, with longer hang times, and exhibit more agile performance. To maximize their capabilities during flights in complex environments, researchers have proposed various model-based perception, planning ...

On the Six-Vertex Model’s Free Energy

open access: yesCommunications in Mathematical Physics, 2022
AbstractIn this paper, we provide new proofs of the existence and the condensation of Bethe roots for the Bethe Ansatz equation associated with the six-vertex model with periodic boundary conditions and an arbitrary density of up arrows (per line) in the regime$$\Delta <1$$Δ<1.

Metacontrol of decision-making strategies in human aging

open access: yeseLife, 2019
Humans employ different strategies when making decisions. Previous research has reported reduced reliance on model-based strategies with aging, but it remains unclear whether this is due to cognitive or motivational factors. Moreover, it is not clear how

Model-Free Plant Tuning

open access: yesIEEE Transactions on Automatic Control, 2017
Given a static plant described by a differentiable input-output function, which is completely unknown, but whose Jacobian takes values in a known polytope in the matrix space, this paper considers the problem of tuning (i.e., driving to a desired value) the output, by suitably choosing the input.

Model-Free Model Reconciliation [PDF]

open access: yesProceedings of the Twenty-Eighth International Joint Conference on Artificial Intelligence, 2019
Designing agents capable of explaining complex sequential decisions remains a significant open problem in human-AI interaction. Recently, there has been a lot of interest in developing approaches for generating such explanations for various decision-making paradigms. One such approach has been the idea of explanation as model-reconciliation.
