A Sequential Markov Probabilistic Aggregation Algorithm for Causal Emergence in Markov Aggregation [PDF]

Entropy
Causal emergence (CE) is a phenomenon in which macrodynamics provide better effective information (EI) than microdynamics. The CE is widely used as the objective function in Markov aggregation. The existing works focus on deterministic aggregation, which

Optogenetic control of mitochondrial aggregation and function

Frontiers in Bioengineering and Biotechnology
The balance of mitochondrial fission and fusion plays an important role in maintaining the stability of cellular homeostasis. Abnormal mitochondrial fission and fragmentation have been shown to be associated with oxidative stress, which causes a variety ...

Personalized neural network-based aggregation function in multi-criteria collaborative filtering

Journal of King Saud University: Computer and Information Sciences
Modeling an effective aggregation function to improve the accuracy of recommendations remains an issue in model-based multi-criteria collaborative filtering (MCCF). The total-based aggregation function is efficient, but it lacks personalization. The user-

Clopidogrel Improves Skin Microcirculatory Endothelial Function in Persons With Heightened Platelet Aggregation

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2016
BackgroundPlatelet activation can lead to enhanced oxidative stress, inflammatory response, and endothelial dysfunction. To quantify the effects of platelet inhibition on endothelial function, we assessed platelet activity of healthy persons before and ...

Choquet-inspired aggregation functions

Information Fusion
In this work, we propose a new family of aggregation functions inspired by the well-known Choquet integral. To build these functions, we replace the measure in the definition of the Choquet integral by an appropriate function. We study the properties of these aggregation functions and explore the relations with some other common aggregation functions ...

Another look at inheritance of uniform continuity of 1-dimensional aggregation functions by their super-additive transformations [PDF]

Journal of Mahani Mathematical Research, 2022
In an earlier paper by Seliga, Siran and the second author (J. Mahani Math. Res. Center 8 (2019) 37–51) on lifting continuity properties of aggregation functions to their super- and sub-additive transformations it was shown that uniform continuity is ...

Learning Aggregation Functions [PDF]

Proceedings of the Thirtieth International Joint Conference on Artificial Intelligence, 2021
Learning on sets is increasingly gaining attention in the machine learning community, due to its widespread applicability. Typically, representations over sets are computed by using fixed aggregation functions such as sum or maximum. However, recent results showed that universal function representation by sum- (or max-) decomposition requires either ...

n-K-Increasing Aggregation Functions

Axioms, 2023
We introduce and discuss the concept of n-ary K-increasing fusion functions and n-ary K-increasing aggregation functions, K being a subset of the index set {1,…,n} indicating in which variables a considered function is increasing. It is also assumed that

Whole-Body Keypoint and Skeleton Augmented RGB Networks for Video Action Recognition

Applied Sciences, 2022
Incorporating multi-modality data is an effective way to improve action recognition performance. Based on this idea, we investigate a new data modality in which Whole-Body Keypoint and Skeleton (WKS) labels are used to capture refined body information ...

Preassociative Aggregation Functions [PDF]

Fuzzy Sets and Systems, 2014
The classical property of associativity is very often considered in aggregation function theory and fuzzy logic. In this paper we provide axiomatizations of various classes of preassociative functions, where preassociativity is a generalization of associativity recently introduced by the authors.
