Rotation Invariant Quantization for Model Compression

Post-training Neural Network (NN) model compression is an attractive approach for deploying large, memory-consuming models on devices with limited memory resources. In this study, we investigate the rate-distortion tradeoff for NN model compression.

libFastMesh: An optimized finite-volume framework for computational aeroacoustics

This paper presents an optimized framework for simulating aeroacoustic flow on unstructured meshes. The libFastMesh (LFM) framework is based on a low-dissipation finite–volume discretization, together with high-order explicit time integration, for direct computation of aeroacoustic fields. These methods were previously...

Hyper Burst Buffer: A Lightweight Burst Buffer I/O Library for High Performance Computing Applications

The growth of computing power of large-scale HPC clusters has lead to the need for large high-bandwidth I/O systems. However, directly writing the large and bursty datasets to centralized parallel file systems can raise significant I/O contention issues on storage...

Assessment of a Flow-dependent Subgrid Characteristic Length for Large-Eddy Simulation on Anisotropic Grids

This paper presents the latest results of a long track development activity in the context of low-dissipative finite volume method for compressible flows. Specifically, here we focus our attention on the Large-Eddy Simulation (LES) approach which can be considered a...

Facial Expression Re-targeting from a Single Character

Video retargeting for digital face animation is used in virtual reality, social media, gaming, movies, and video conference, aiming to animate avatars' facial expressions based on videos of human faces. The standard method to represent facial expressions for 3D characters...

FACIAL EXPRESSION RE-TARGETING FROM A SINGLE CHARACTER

Video retargeting for digital face animation is used in virtual reality, social media, gaming, movies, and video conference, aiming to animate avatars’ facial expressions based on videos of human faces. The standard method to represent facial expressions for 3D characters...

A Full Duplex RF Front End Employing an Electrical Balanced Duplexer and a Chebyshev Load-Balancing Filter

This paper presents a new Chebyshev load-balance (LB) circuit for electrical-balanced RF front-ends targeted for simultaneous transmit-receive (STR) operation. TX reflection of a commercial Wi-Fi antenna with near 3:1 VSWR and direct TX leakage of a commercial quadrature-hybrid are considered...

Theoretical Bounds of the Self-Interference Cancellation-Bandwidth Integral in Full Duplex RF Front Ends

This paper studies the behavior of lumped self-interference cancellation (SIC) filters in simultaneous transmit-receive (STR) RF front ends. The crux that enables a different approach in this work for finding an optimal network solution is converting the SIC circuit design...
