Federated learning with hyper-parameter optimization

open access: yesJournal of King Saud University: Computer and Information Sciences, 2023
Federated Learning is a new approach for distributed training of a deep learning model on data scattered across a large number of clients while ensuring data privacy.

Test–retest reliability of reinforcement learning parameters [PDF]

open access: yesBehavior Research Methods, 2023
AbstractIt has recently been suggested that parameter estimates of computational models can be used to understand individual differences at the process level. One area of research in which this approach, called computational phenotyping, has taken hold is computational psychiatry.

W-Trans: A Weighted Transition Matrix Learning Algorithm for the Sensor-Based Human Activity Recognition

open access: yesIEEE Access, 2020
The sensor-based human activity recognition has been wildly applied in behavior tracking, health monitoring, indoor localization etc. Using activity continuity to assist activity recognition is an important research issue, in which the activity ...

A Novel Qualitative Maximum a Posteriori Estimation for Bayesian Network Parameters Based on Computing the Center Point of Constrained Parameter Regions

open access: yesIEEE Access, 2022
Introducing parameter constraints has become a mainstream approach for learning Bayesian network parameters with small datasets. The QMAP (Qualitative Maximum a Posteriori) estimation has produced the best learning accuracy among existing learning ...

Learning physical parameters from dynamic scenes [PDF]

open access: yesCognitive Psychology, 2018
Humans acquire their most basic physical concepts early in development, and continue to enrich and expand their intuitive physics throughout life as they are exposed to more and varied dynamical environments. We introduce a hierarchical Bayesian framework to explain how people can learn physical parameters at multiple levels.

Active learning BSM parameter spaces

open access: yesEuropean Physical Journal C: Particles and Fields, 2023
Active learning (AL) has interesting features for parameter scans of new models. We show on a variety of models that AL scans bring large efficiency gains to the traditionally tedious work of finding boundaries for BSM models.

Construction and Reasoning Approach of Belief Rule-Base for Classification Base on Decision Tree

open access: yesIEEE Access, 2020
The classical belief rule-based (BRB) systems are usually constructed by arranging and combining referential values of antecedent attributes or by setting special fixed values, which can lead to overly large size of BRB systems in complex problems.

Manifold learning for parameter reduction

open access: yesJournal of Computational Physics, 2019
Large scale dynamical systems (e.g. many nonlinear coupled differential equations) can often be summarized in terms of only a few state variables (a few equations), a trait that reduces complexity and facilitates exploration of behavioral aspects of otherwise intractable models.

Research on Intelligent Maneuvering Decision-Making in Close Air Combat Based on Deep Q Network [PDF]

open access: yesHangkong bingqi, 2023
Aiming at the problem of UCAV maneuvering decision-making in close air combat, the design of reinforcement learning reward function and the selection of hyper-parameters are studied based on the framework of deep Q network algorithm.

Parameter learning in production economies

open access: yesJournal of Monetary Economics, 2018
We examine how parameter learning amplifies the impact of macroeconomic shocks on equity prices and quantities in a standard production economy where a representative agent has Epstein-Zin preferences. An investor observes technology shocks which follow a regime-switching process but does not know the underlying model parameters governing the short ...
