Enhancing generalized spectral clustering with embedding Laplacian graph regularization

CAAI Transactions on Intelligence Technology, EarlyView.
Abstract An enhanced generalised spectral clustering framework that addresses the limitations of existing methods by incorporating the Laplacian graph and group effect into a regularisation term is presented. By doing so, the framework significantly enhances discrimination power and proves highly effective in handling noisy data.

Higher Jordan triple derivations on ∗-type trivial extension algebras

AIMS Mathematics
In this paper, we investigated the problem of describing the form of higher Jordan triple derivations on trivial extension algebras. We show that every higher Jordan triple derivation on a $ 2 $-torsion free $ * $-type trivial extension algebra is a sum ...

How Can Inflation Contracts Discipline Central Bankers When Agents Are Learning?

Bulletin of Economic Research, EarlyView.
ABSTRACT This paper studies, in a new Keynesian model with a positive optimal output gap, how to design linear inflation contracts to shape the central bank's incentive structure when private expectations are based on adaptive learning. In this model, under rational expectations, inflation contracts could only partially deal with the time‐inconsistency

Market Allocations Under Conflation of Goods

International Economic Review, EarlyView.
ABSTRACT We study competitive equilibria in exchange economies when a continuum of goods is conflated into a finite set of commodities. The design of conflation choices affects the allocation of scarce resources among agents, by constraining trading opportunities and shifting competitive pressures.

On Derivations of Certain Algebras Related to Irreducible Triangular Algebras [PDF]

Transactions of the American Mathematical Society, 1983
This paper deals with derivations on algebras that are generated by a maximal abelian selfadjoint algebra of operators A \mathcal {A} on a Hilbert space and a group of unitary operators acting on it. A necessary and sufficient condition for such a derivation to be implemented by an operator affiliated with ...

Topological Data Analysis Based Characteristics of Electroencephalogram Signals in Children With Sleep Apnea

Journal of Sleep Research, EarlyView.
ABSTRACT This study aims to identify differences in the functional neural connectivity of the brain of paediatric patients with obstructive sleep apnea. Using EEG signals from 3673 paediatric patients, we grouped subjects into OSA or control groups based on sleep oxygen desaturation levels and apnea‐hypopnea index (AHI), and applied topological data ...

Jordan maps on triangular algebras

Linear Algebra and its Applications, 2007
AbstractLet T be a triangular algebra and R′ be an arbitrary ring. Suppose that M:T→R′ and M∗:R′→T are surjective maps such thatM(aM∗(x)+M∗(x)a)=M(a)x+xM(a),M∗(M(a)x+xM(a))=aM∗(x)+M∗(x)afor all a∈T,x∈R′. In this paper, we give sufficient conditions on T such that both M and M∗ are additive. In particular, if T is a standard subalgebra of a nest algebra,

Empirical likelihood for martingale differences

Journal of Time Series Analysis, EarlyView.
In this article, we consider an empirical likelihood with vector observations that are martingale differences and prove a Wilks' type theorem under a conditional Lindeberg condition. We then generalize this result to approximate martingale differences.
