Inductive Moment Matching

CoRR
Diffusion models and Flow Matching generate high-quality samples but are slow at inference, and distilling them into few-step models often leads to instability and extensive tuning. To resolve these trade-offs, we propose Inductive Moment Matching (IMM), a new class of generative models for one- or few-step sampling with a single-stage training ...

EXIT Chart Analysis of Expectation Propagation-Based Iterative Detection and Decoding

IEEE Open Journal of the Communications Society
This paper proposes a novel framework for extrinsic information transfer (EXIT) chart analysis to examine the convergence behavior of iterative detection and decoding (IDD) algorithms based on expectation propagation (EP), specifically addressing the ...

Gramian Preserving Moment Matching for Linear Systems*

2023 European Control Conference (ECC), 2023
Time-domain moment matching-based model order reduction is an efficient technique that provides a family of parametrized reduced order models with identical moments evaluated in a set of points. The free parameters provide flexibility to impose additional constraints such as stability, passivity, and derivative matching.

A Moment-Based Shape Similarity Measurement for Areal Entities in Geographical Vector Data

ISPRS International Journal of Geo-Information, 2018
Shape similarity measurement model is often used to solve shape-matching problems in geospatial data matching. It is widely used in geospatial data integration, conflation, updating and quality assessment. Many shape similarity measurements apply only to

Health Literacy, Self‐Efficacy and Knowledge of Sickle Cell Disease Among Caregivers

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Sickle cell disease (SCD) is a hereditary blood disorder in which abnormal haemoglobin leads to severe anaemia, painful crises and organ failure. Caregivers’ health literacy (HL) – their ability to assess, understand and apply information, and interact with healthcare professionals – is crucial for managing children with SCD, yet ...

A revised moment error expression for the AIRGA algorithm

Analele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2018
The fully adaptive rational global Arnoldi method (AIRGA) for the modelorder reduction of second-order multi-input multi-output systems with proportional damping is revisited. The method automatically generates a reduced system approximating the transfer

Multivariate moment-matching for model order reduction of quadratic-bilinear systems using error bounds

Advanced Modeling and Simulation in Engineering Sciences, 2022
We propose an adaptive moment-matching framework for model order reduction of quadratic-bilinear systems. In this framework, an important issue is the selection of those shift frequencies where moment-matching is to be achieved.

Measurable Residual Disease Monitoring During Treatment for Pediatric Acute Myeloid Leukemia in First Relapse

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Survival after relapse in pediatric acute myeloid leukemia (AML) remains poor, highlighting the critical importance of identifying prognostic factors to guide optimal relapse management. Methods We investigated the prognostic impact of multiparameter flow cytometry (MFC) measurable residual disease (MRD) in 188 patients with first ...

Approximation of Any Particle Size Distribution Employing a Bidisperse One Based on Moment Matching

Colloids and Interfaces
Dispersed phases like colloidal particles and emulsions are characterized by their particle size distribution. Narrow distributions can be represented by the monodisperse distribution. However, this is not the case for broader distributions.
