Subgroup Discovery in Machine Learning Problems with Formal Concepts Analysis and Test Theory Algorithms

Algorithms, 2023
A number of real-world problems of automatic grouping of objects or clustering require a reasonable solution and the possibility of interpreting the result. More specific is the problem of identifying homogeneous subgroups of objects.

Exponential and weakly exponential subgroups of finite groups [PDF]

International Journal of Group Theory
Sabatini [L. Sabatini, Products of subgroups, subnormality, and relative orders of elements, Ars Math. Contemp., 24 no. 1 (2024) 9 pp.] defined a subgroup $H$ of $G$ to be an exponential subgroup if $x^{|G:H|} \in H$ for all $x \in G$, in which case we ...

Outcomes of Live Virus Vaccination in Patients With Vascular Anomalies Being Treated With Sirolimus

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Live vaccination in patients with vascular anomalies (VA) receiving sirolimus remains controversial due to immunosuppressive effects and theoretical risks. Procedure This single‐center retrospective study included patients with VA less than 4 years old at the start of sirolimus therapy who were incompletely vaccinated.

On the factorised subgroups of products of cyclic and non-cyclic finite $p$-groups

Comptes Rendus. Mathématique
Let $p$ be an odd prime and let $ G = AB $ be a finite $p$-group that is the product of a cyclic subgroup $A$ and a non-cyclic subgroup $B$. Suppose in addition that the nilpotency class of $B$ is less than $\frac{p}{2}$.

Smokers’ strategies to reduce tobacco spending: self-reported use and differences across subgroups. Findings from the International Tobacco Control (ITC) Netherlands Survey

BMC Public Health, 2023
Background The cost of tobacco is one of the most reported reasons for smoking cessation. Rather than quitting, smokers can use also strategies to reduce tobacco expenditure while continuing smoking, such as smoking less or using price-minimising ...

SURFACE SUBGROUPS OF GRAPH PRODUCTS OF GROUPS [PDF]

International Journal of Algebra and Computation, 2012
Let G be a graph product of a collection of groups and H be the direct product of the same collection of groups, so that there is a natural surjection p : G → H. The kernel of this map p is called a graph product kernel. We prove that a graph product kernel of countable groups is special, and a graph product of finite or cyclic groups is virtually ...
