Voice-Face Homogeneity Tells Deepfake [PDF]

ACM Trans. Multim. Comput. Commun. Appl., 2022
Detecting forgery videos is highly desirable due to the abuse of deepfake. Existing detection approaches contribute to exploring the specific artifacts in deepfake videos and fit well on certain data.

Virtual Homogeneity Learning: Defending against Data Heterogeneity in Federated Learning [PDF]

International Conference on Machine Learning, 2022
In federated learning (FL), model performance typically suffers from client drift induced by data heterogeneity, and mainstream works focus on correcting client drift.

Polyamide-based membranes with structural homogeneity for ultrafast molecular sieving

Nature Communications, 2022
Thin-film composite membranes formed by conventional interfacial polymerization generally suffer from the depth heterogeneity of the polyamide layer, i.e., nonuniformly distributed free volume pores, leading to the inefficient permselectivity.

Statistical tests for homogeneity of variance for clinical trials and recommendations

Contemporary Clinical Trials Communications, 2023
In most clinical trials, the main interest is to test whether there are differences in the mean outcomes among the treatment groups. When the outcome is continuous, a common statistical test is a usual t-test for a two-group comparison.

On the elimination of the sweeping interactions from theories of hydrodynamic turbulence [PDF]

, 2006
In this paper, we revisit the claim that the Eulerian and quasi-Lagrangian same time correlation tensors are equal. This statement allows us to transform the results of an MSR quasi-Lagrangian statistical theory of hydrodynamic turbulence back to the ...

Testing Slope Homogeneity in Large Panels

Social Science Research Network, 2005
This paper proposes a modi?ed version of Swamy’s test of slope homogeneity for panel data models where the cross section dimension (N) could be large relative to the time series dimension (T).

Preparation of a reference material for microplastics in water—evaluation of homogeneity

Analytical and Bioanalytical Chemistry, 2021
Validation of analytical methods for measurements of microplastics (MP) is severely hampered because of a general lack of reference materials, RM. There is a great need to develop such reference materials. This study presents a concept of three-component

“Homogenization with non‐homogeneous plastic flow”

International Journal for Numerical and Analytical Methods in Geomechanics, 2023
AbstractThis paper provides the solution of a homogenization model that simultaneously considers the plastic and elastic strain fields in a single analytical formulation. In addition, the authors aim to decouple plastic flows triggered in the inclusions, in the matrix at the interfaces with the inclusions, and in the matrix at a large distance from the

Characterization of Structural Defects in (Cd,Zn)Te Crystals Grown by the Travelling Heater Method

Crystals, 2021
Structural defects and compositional uniformity remain the major problems affecting the performance of (Cd, Zn)Te (CZT) based detector devices. Understanding the mechanism of growth and defect formation is therefore fundamental to improving the crystal ...
