Mitigating Data Injection Attacks on Federated Learning

no code implementations4 Dec 2023 Or Shalom, Amir Leshem, Waheed U. Bajwa

However, despite its advantages, federated learning can be susceptible to false data injection attacks.

Fair Multi-Agent Bandits

no code implementations7 Jun 2023 Amir Leshem

This significantly improves previous results which had the same upper bound on the regret of order $O(f(\log T) \log T )$ but an exponential dependence on the number of agents.

Communication Efficient Distributed Learning over Wireless Channels

no code implementations4 Sep 2022 Idan Achituve, Wenbo Wang, Ethan Fetaya, Amir Leshem

Vertical distributed learning exploits the local features collected by multiple learning workers to form a better global model.

Medium Access Control protocol for Collaborative Spectrum Learning in Wireless Networks

no code implementations25 Oct 2021 Tomer Boyarski, Wenbo Wang, Amir Leshem

Based on the algorithm we provide a medium access control protocol which allows distributed implementation of the algorithm in ad-hoc networks.

Distributed Deep Reinforcement Learning for Collaborative Spectrum Sharing

no code implementations6 Apr 2021 Pranav M. Pawar, Amir Leshem

In this paper, we combine game-theoretic insights with deep Q-learning to provide a novel asymptotically optimal solution to the spectrum collaboration problem.

Multi-Gigabit Wireline Systems over Copper: An Interference Cancellation Perspective

no code implementations17 May 2020 S. M. Zafaruddin, Amir Leshem

Interference cancellation is the main driving technology in enhancing the transmission rates over telephone lines above 100 Mbps.

Decentralized Learning for Channel Allocation in IoT Networks over Unlicensed Bandwidth as a Contextual Multi-player Multi-armed Bandit Game

1 code implementation30 Mar 2020 Wenbo Wang, Amir Leshem, Dusit Niyato, Zhu Han

We study a decentralized channel allocation problem in an ad-hoc Internet of Things network underlaying on the spectrum licensed to a primary cellular network.

The Restless Hidden Markov Bandit with Linear Rewards and Side Information

no code implementations22 Oct 2019 Michal Yemini, Amir Leshem, Anelia Somekh-Baruch

Furthermore, we assume structural side information where the decision maker knows in advance that there are two types of hidden states; one is common to all arms and evolves according to a Markovian distribution, and the other is unique to each arm and is distributed according to an i. i. d.

Distributed Learning for Channel Allocation Over a Shared Spectrum

no code implementations17 Feb 2019 S. M. Zafaruddin, Ilai Bistritz, Amir Leshem, Dusit Niyato

When the CSI is time varying and unknown to the users, the users face the challenge of both learning the channel statistics online and converge to a good channel allocation.

Distributed Multi-Player Bandits - a Game of Thrones Approach

no code implementations NeurIPS 2018 Ilai Bistritz, Amir Leshem

Each player has different expected rewards for the arms, and the instantaneous rewards are independent and identically distributed.

Decentralized Caching for Content Delivery Based on Blockchain: A Game Theoretic Perspective

no code implementations23 Jan 2018 Wenbo Wang, Dusit Niyato, Ping Wang, Amir Leshem

In this paper, we propose a decentralized framework of proactive caching in a hierarchical wireless network based on blockchains.

RIDS: Robust Identification of Sparse Gene Regulatory Networks from Perturbation Experiments

no code implementations20 Dec 2016 Hoi-To Wai, Anna Scaglione, Uzi Harush, Baruch Barzel, Amir Leshem

To overcome this challenge, we develop the Robust IDentification of Sparse networks (RIDS) method that reconstructs the GRN from a small number of perturbation experiments.

Active Sensing of Social Networks

no code implementations21 Jan 2016 Hoi-To Wai, Anna Scaglione, Amir Leshem

The model used for the regression is based on the steady state equation in the linear DeGroot model under the influence of stubborn agents, i. e., agents whose opinions are not influenced by their neighbors.

Algorithms for Linear Bandits on Polyhedral Sets

no code implementations26 Sep 2015 Manjesh K. Hanawal, Amir Leshem, Venkatesh Saligrama

We then provide a nearly optimal algorithm and show that its expected regret scales as $O(N\log^{1+\epsilon}(T))$ for an arbitrary small $\epsilon >0$.

A Gaussian Tree Approximation for Integer Least-Squares

no code implementations NeurIPS 2009 Jacob Goldberger, Amir Leshem

The factor graph that corresponds to this problem is very loopy; in fact, it is a complete graph.
