Implementation of digital MemComputing using standard electronic components

1 code implementation21 Sep 2023 Yuan-Hang Zhang, Massimiliano Di Ventra

Digital MemComputing machines (DMMs), which employ nonlinear dynamical systems with memory (time non-locality), have proven to be a robust and scalable unconventional computing approach for solving a wide variety of combinatorial optimization problems.

Self-averaging of digital memcomputing machines

1 code implementation20 Jan 2023 Daniel Primosch, Yuan-Hang Zhang, Massimiliano Di Ventra

Digital memcomputing machines (DMMs) are a new class of computing machines that employ non-quantum dynamical systems with memory to solve combinatorial optimization problems.

Directed percolation and numerical stability of simulations of digital memcomputing machines

no code implementations6 Feb 2021 Yuan-Hang Zhang, Massimiliano Di Ventra

To investigate the reasons behind the robustness and effectiveness of this method, we employ three explicit integration schemes (forward Euler, trapezoid and Runge-Kutta 4th order) with a constant time step, to solve 3-SAT instances with planted solutions.

Topological Quantum Compiling with Reinforcement Learning

1 code implementation9 Apr 2020 Yuan-Hang Zhang, Pei-Lin Zheng, Yi Zhang, Dong-Ling Deng

Quantum compiling, a process that decomposes the quantum algorithm into a series of hardware-compatible commands or elementary gates, is of fundamental importance for quantum computing.

Deformation Flow Based Two-Stream Network for Lip Reading

1 code implementation12 Mar 2020 Jing-Yun Xiao, Shuang Yang, Yuan-Hang Zhang, Shiguang Shan, Xilin Chen

Observing on the continuity in adjacent frames in the speaking process, and the consistency of the motion patterns among different speakers when they pronounce the same phoneme, we model the lip movements in the speaking process as a sequence of apparent deformations in the lip region.

$M^3$T: Multi-Modal Continuous Valence-Arousal Estimation in the Wild

1 code implementation7 Feb 2020 Yuan-Hang Zhang, Rulin Huang, Jiabei Zeng, Shiguang Shan, Xilin Chen

This report describes a multi-modal multi-task ($M^3$T) approach underlying our submission to the valence-arousal estimation track of the Affective Behavior Analysis in-the-wild (ABAW) Challenge, held in conjunction with the IEEE International Conference on Automatic Face and Gesture Recognition (FG) 2020.

LRW-1000: A Naturally-Distributed Large-Scale Benchmark for Lip Reading in the Wild

2 code implementations16 Oct 2018 Shuang Yang, Yuan-Hang Zhang, Dalu Feng, Mingmin Yang, Chenhao Wang, Jing-Yun Xiao, Keyu Long, Shiguang Shan, Xilin Chen

It has shown a large variation in this benchmark in several aspects, including the number of samples in each class, video resolution, lighting conditions, and speakers' attributes such as pose, age, gender, and make-up.
