CCSMR: A Combinatorial Category Space-Based Model for Recommendation

open access: yesIEEE Access, 2019
Various side information has been exploited in recommender systems to help users finding items they prefer to alleviate data sparsity. Because item category can be used to view the user's preference in a high-level scope and an item can have more than ...

Category Theory Framework for System Engineering and Safety Assessment Model Synchronization Methodologies

open access: yesApplied Sciences, 2022
In recent decades, there has been a significant increase in systems’ complexity, leading to a rise in the need for more and more models. Models created with different intents are written using different formalisms and give diverse system representations.

On Combinatorial Model Categories [PDF]

open access: yesApplied Categorical Structures, 2008
Combinatorial model categories were introduced by J. H. Smith as model categories which are locally presentable and cofibrantly generated. He has not published his results yet but proofs of some of them were presented by T. Beke or D. Dugger. We are contributing to this endeavour by proving that weak equivalences in a combinatorial model category form ...

Toward A Dual-Learning Systems Model of Speech Category Learning

open access: yesFrontiers in Psychology, 2014
More than two decades of work in vision posits the existence of dual-learning systems of category learning. The reflective system uses working memory to develop and test rules for classifying in an explicit fashion, while the reflexive system operates by

Category-Theoretic Formulation of the Model-Based Systems Architecting Cognitive-Computational Cycle

open access: yesApplied Sciences, 2021
We introduce the Concept→Model→Graph→View Cycle (CMGVC). The CMGVC facilitates coherent architecture analysis, reasoning, insight, and decision making based on conceptual models that are transformed into a generic, robust graph data structure (GDS).

Model categories with simple homotopy categories

open access: yesTheory and Applications of Categories, 2015
In the present article, we describe constructions of model structures on general bicomplete categories. We are motivated by the following question: given a category $\mathcal{C}$ with a subcategory $w\mathcal{C}$ closed under retracts, when is there a model structure on $\mathcal{C}$ with $w\mathcal{C}$ as the subcategory of weak equivalences? We begin

Homotopy theory of Moore flows (II)

open access: yesExtracta Mathematicae, 2021
This paper proves that the q-model structures of Moore flows and of multipointed d-spaces are Quillen equivalent. The main step is the proof that the counit and unit maps of the Quillen adjunction are isomorphisms on the q-cofibrant objects (all objects ...

Implementation of the Inquiry Model on the Critical Thinking Ability of Prospective Physical Education Teachers in Football Learning

open access: yesPhysical Activity Journal, 2023
Currently, football needs to be supported by critical thinking skills to produce a focused and efficient game. This research aims to implement an inquiry learning model on students' critical thinking skills in football learning ...

Detecting model categories among Quillen categories using homotopies

open access: yesTheory and Applications of Categories, 2022
A Quillen category is a category equipped with two weak factorization systems \((\mathcal{C},\mathcal{F}_t)\) and \((\mathcal{C}_t,\mathcal{F})\) such that \(\mathcal{C}_t\subset \mathcal{C}\) and \(\mathcal{F}_t\subset \mathcal{F}\). Every model category gives rise to a Quillen category. The paper gives conditions so that a Quillen category gives rise
