IsoBN: Fine-Tuning BERT with Isotropic Batch Normalization
Proceedings of the AAAI Conference on Artificial Intelligence, 2021 Fine-tuning pre-trained language models (PTLMs), such as BERT and its better variant RoBERTa, has been a common practice for advancing performance in natural language understanding (NLU) tasks. Recent advance in representation learning shows that isotropic (i.e., unit-variance and uncorrelated) embeddings can significantly improve performance on ...

Normal Waves in an Electromagnetic Metachiral Isotropic Medium with Losses [PDF]
Russian Physics Journal, 2020 Plane electromagnetic waves in an isotropic absorbing chiral medium (chiral metamaterial) are considered. A system of constitutive Drude - Born - Fedorov relations with complex values of the dielectric permittivity, magnetic permeability, and the chirality parameter is used. A distinction is made between forward and backward normal waves by introducing

Anisotropic neighborhood searching for point cloud with sharp feature
Measurement + Control, 2020 The k-nearest neighborhoods (kNN) of feature points of complex surface model are usually isotropic, which may lead to sharp feature blurring during data processing, such as noise removal and surface reconstruction. To address this issue, a new method was

Three Dimensional Vibration of an Isotropic Plate Enclosed in a Rigid Body
Hittite Journal of Science and Engineering, 2022 In this study, vibration of plates embedded in a rigid enclosure has been investigated analytically for the first time in the literature. It is assumed that the isotropic plate is always in contact with outer enclosure. Therefore, the normal displacement

Dynamic wormholes with particle creation mechanism [PDF]
, 2015 The present work deals with a spherically symmetric space-time which is asymptotically (at spatial infinity) FRW space-time and represents wormhole configuration: The matter component is divided into two parts--(a) dissipative but homogeneous and ...

A strategy to formulate data-driven constitutive models from random multiaxial experiments
Scientific Reports, 2022 We present a test technique and an accompanying computational framework to obtain data-driven, surrogate constitutive models that capture the response of isotropic, elastic–plastic materials loaded in-plane stress by combined normal and shear stresses ...

Axisymmetric deformations in a nonlocal isotropic thermoelastic solid with two temperature
Forces in Mechanics, 2022 The paper is devoted to the study of the axisymmetric deformations in a two-dimensional nonlocal homogeneous isotropic thermoelastic solid without energy dissipation. The effect of two temperature has been added with normal force over the circular region,
