Curvature accelerated decentralized non-convex optimization for high-dimensional machine learning problems
Dingran Yi, Fanhao Zeng, Nikolaos M. Freris
We consider distributed optimization as motivated by machine learning in a multi-agent system: each agent holds local data and the goal is to minimize an aggregate loss function ov…
Anteumbler: Non-Invasive Antenna Orientation Error Measurement for WiFi APs
Dawei Yan, Panlong Yang, Fei Shang +2
The performance of WiFi-based localization systems is affected by the spatial accuracy of WiFi AP. Compared with the imprecision of AP location and antenna separation, the imprecis…
Communication-efficient distributed optimization with adaptability to system heterogeneity
Ziyi Yu, Nikolaos M. Freris
We consider the setting of agents cooperatively minimizing the sum of local objectives plus a regularizer on a graph. This paper proposes a primal-dual method in consideration of t…
TPMDP: Threshold Personalized Multi-party Differential Privacy via Optimal Gaussian Mechanism
Jiandong Liu, Lan Zhang, Chaojie Lv +3
In modern distributed computing applications, such as federated learning and AIoT systems, protecting privacy is crucial to prevent adversarial parties from colluding to steal othe…
SpiRobs: Logarithmic Spiral-shaped Robots for Versatile Grasping Across Scales
Zhanchi Wang, Nikolaos M. Freris, Xi Wei
Realizing a soft manipulator with biologically comparable flexibility and versatility often requires careful selection of materials and actuation, as well as attentive design of it…
Distributed optimization on directed graphs based on inexact ADMM with partial participation
Dingran Yi, Nikolaos M. Freris
We consider the problem of minimizing the sum of cost functions pertaining to agents over a network whose topology is captured by a directed graph (i.e., asymmetric communication).…
