Ordinary Differential Equation-based MIMO Signal Detection
Ayano Nakai-Kasai, Tadashi Wadayama
The required signal processing rate in future wireless communication systems exceeds the performance of the latest electronics-based processors. Introduction of analog optical comp…
Stochastic Dynamics of Noisy Average Consensus: Analysis and Optimization
Tadashi Wadayama, Ayano Nakai-Kasai
A continuous-time average consensus system is a linear dynamical system defined over a graph, where each node has its own state value that evolves according to a simultaneous linea…
Ordinary Differential Equation-based Sparse Signal Recovery
Tadashi Wadayama, Ayano Nakai-Kasai
This study investigates the use of continuous-time dynamical systems for sparse signal recovery. The proposed dynamical system is in the form of a nonlinear ordinary differential e…
Gradient Flow Decoding for LDPC Codes
Tadashi Wadayama, Kensho Nakajima, Ayano Nakai-Kasai
The power consumption of the integrated circuit is becoming a significant burden, particularly for large-scale signal processing tasks requiring high throughput. The decoding proce…
Deep Unfolding-based Weighted Averaging for Federated Learning in Heterogeneous Environments
Ayano Nakai-Kasai, Tadashi Wadayama
Federated learning is a collaborative model training method that iterates model updates by multiple clients and aggregation of the updates by a central server. Device and statistic…
Deterministic Fault-Tolerant Connectivity Labeling Scheme
Taisuke Izumi, Yuval Emek, Tadashi Wadayama +1
The \emph{-fault-tolerant connectivity labeling} (-FTC labeling) is a scheme of assigning each vertex and edge with a small-size label such that one can determine the connect…
