Contention detection by throttling: A black-box on-line approach

2015

Visualization technology powers up the cloud computing paradigm and inevitably raises concerns about performance isolation of collocated virtual machines (VM). It is imperative for public cloud providers to guarantee performance targets for tenants' VMs while …

Profiling Memory Vulnerability of Big-Data Applications

2016

Motivated by the increasing popularity of hosting in-memory big-data analytics in cloud, we present a profiling methodology that can understand how different memory subsystems, i.e., cache and memory bandwidth, are susceptible to the impact of …

DTGAN: Differential Private Training for Tabular GANs

2021 · arXiv (Cornell University)

Tabular generative adversarial networks (TGAN) have recently emerged to cater to the need of synthesizing tabular data -- the most widely used data format. While synthetic tabular data offers the advantage of complying with privacy …

BatMan-CLR: Making Few-shots Meta-Learners Resilient Against Label Noise

2023 · arXiv (Cornell University)

The negative impact of label noise is well studied in classical supervised learning yet remains an open research question in meta-learning. Meta-learners aim to adapt to unseen learning tasks by learning a good initial model …

A Performance Analysis for Confidential Federated Learning

2024

Federated Learning (FL) has emerged as a solution to preserve data privacy by keeping the data locally on each participant’s device. However, FL alone is still vulnerable to attacks that can cause privacy leaks. Therefore, …
