Federated Learning with Flexible Control

no code implementations16 Dec 2022 Shiqiang Wang, Jake Perazzone, Mingyue Ji, Kevin S. Chan

In this paper, we address this problem and propose FlexFL - an FL algorithm with multiple options that can be adjusted flexibly.

Joint Coreset Construction and Quantization for Distributed Machine Learning

no code implementations13 Apr 2022 Hanlin Lu, Changchang Liu, Shiqiang Wang, Ting He, Vijay Narayanan, Kevin S. Chan, Stephen Pasteris

Coresets are small, weighted summaries of larger datasets, aiming at providing provable error bounds for machine learning (ML) tasks while significantly reducing the communication and computation costs.

Communication-efficient k-Means for Edge-based Machine Learning

no code implementations8 Feb 2021 Hanlin Lu, Ting He, Shiqiang Wang, Changchang Liu, Mehrdad Mahdavi, Vijaykrishnan Narayanan, Kevin S. Chan, Stephen Pasteris

We consider the problem of computing the k-means centers for a large high-dimensional dataset in the context of edge-based machine learning, where data sources offload machine learning computation to nearby edge servers.

Connecting the Dots: Detecting Adversarial Perturbations Using Context Inconsistency

no code implementations ECCV 2020 Shasha Li, Shitong Zhu, Sudipta Paul, Amit Roy-Chowdhury, Chengyu Song, Srikanth Krishnamurthy, Ananthram Swami, Kevin S. Chan

There has been a recent surge in research on adversarial perturbations that defeat Deep Neural Networks (DNNs) in machine vision; most of these perturbation-based attacks target object classifiers.

Sharing Models or Coresets: A Study based on Membership Inference Attack

no code implementations6 Jul 2020 Hanlin Lu, Changchang Liu, Ting He, Shiqiang Wang, Kevin S. Chan

Distributed machine learning generally aims at training a global model based on distributed data without collecting all the data to a centralized location, where two different approaches have been proposed: collecting and aggregating local models (federated learning) and collecting and training over representative data summaries (coreset).

A4 : Evading Learning-based Adblockers

no code implementations29 Jan 2020 Shitong Zhu, Zhongjie Wang, Xun Chen, Shasha Li, Umar Iqbal, Zhiyun Qian, Kevin S. Chan, Srikanth V. Krishnamurthy, Zubair Shafiq

Efforts by online ad publishers to circumvent traditional ad blockers towards regaining fiduciary benefits, have been demonstrably successful.

GLEE: Geometric Laplacian Eigenmap Embedding

3 code implementations23 May 2019 Leo Torres, Kevin S. Chan, Tina Eliassi-Rad

Graph embedding seeks to build a low-dimensional representation of a graph G. This low-dimensional representation is then used for various downstream tasks.

Learning and Planning in the Feature Deception Problem

no code implementations13 May 2019 Zheyuan Ryan Shi, Ariel D. Procaccia, Kevin S. Chan, Sridhar Venkatesan, Noam Ben-Asher, Nandi O. Leslie, Charles Kamhoua, Fei Fang

In order to formally reason about deception, we introduce the feature deception problem (FDP), a domain-independent model and present a learning and planning framework for finding the optimal deception strategy, taking into account the adversary's preferences which are initially unknown to the defender.

Robust Coreset Construction for Distributed Machine Learning

no code implementations11 Apr 2019 Hanlin Lu, Ming-Ju Li, Ting He, Shiqiang Wang, Vijaykrishnan Narayanan, Kevin S. Chan

Coreset, which is a summary of the original dataset in the form of a small weighted set in the same sample space, provides a promising approach to enable machine learning over distributed data.
