Differential privacy is a widely accepted notion of statistical privacy. Besides, I am also interested in evaluating the privacy risks of machine learning models (e.g., membership inference, property inference, etc), and defending these potential threats using . First, I will present a practical DP training framework for centralized setting with better empirical and theoretical utility (IJCAI'21). (1) Local DP is comprised of applying noise directly to the user data. The models should not expose private information in these datasets. efficiently protect user privacy in a collaborative bandit learning environment remains unknown. , R.Shokri et al. ) The intellectual impact of di erential privacy has been broad, with in uence on the thinking about privacy being noticeable in a huge range of disciplines, ranging from traditional areas of computer science (databases, machine learning, networking, In this talk, I will present our recent work on achieving 1) differential privacy (DP) to ensure privacy of the training data and 2) certified robustness against adversarial examples for deep learning models. We thus consider local gradients as private information to be protected. Recent advances in differentially private deep learning have demonstrated that the application of differential privacy-- specifically the DP-SGD algorithm-- has a disparate impact on different sub-groups in the population, which leads to a significantly high drop-in model utility for sub-populations that are under-represented (minorities . Springer . In the GDP setting, there is a trusted curator who applies carefully calibrated random noise to the real values returned for a particular query. import nest_asyncio. that other attempts at de ning privacy have faced. Differential privacy, on the other hand, looks at the ML system as a whole, and cares about protecting the privacy of the training set, used to train the model. Before we begin. With Non-IID (Not Independent and Identically Distributed) issues existing in the federated learning setting, a myriad of approaches has been proposed to crack this hard nut.

Time Series Analysis of Production Decline in Carbonate Reservoirs with Machine Learning. While numerous techniques have been proposed for privacy-preserving deep learning over non-relational data, there is less work addressing the privacy issues pertained to applying . differential privacy if for all pairs of neighboring data sets Yand Y0that differ in only a single observation P(A(Y) 2S) e P(A(Y0) 2S); (1) for all subsets Sin the range of A( ). This is generally achieved by randomizing the output of the computation through the addition of noise [ Dwork et al., 2014 ]. I received my PhD in Computer Science from Georgia Institute of Technology in Spring 2022. 2 Preliminaries This section provides preliminaries and background infor- Two databases D and D′ are neighbors if they differ in only one entry. Extensive experiments are conducted on three large-scale Re-ID datasets Market1501, CUHK03, MSMT17, and two other occluded datasets. In this paper, we aim to develop a novel mechanism to preserve differential privacy (DP) in lifelong learning (L2M) for deep neural networks. We will focus on PATE Analysis, specifically. submodel learning scheme coupled with a private set union pro-tocol as a cornerstone. To the best of our knowledge, this is the first work that studies and provides theoretical guarantees for the stochastic linear combination of non-linear regressions model. . Featuring Dmitrii Usynin - Speaker at #PriCon2020 - Sept 26 & 27 With the upcoming OpenMined Private Conference 2020 around the corner Don't worry if you are not familiar with these terms as we will introduce these concepts first. Local Differential Privacy for Deep Learning M.A.P. As depicted in Figure 1, global differential privacy (GDP) and local differential privacy (LDP) are two approaches that can be used by randomized algorithms to achieve differential privacy. 7, no. Dec 2022 I am invited as a reviewer for CVPR22. Each client train local model using DP-SGD ( [2], tensorflow-privacy) to perturb model parameters. Local DP is used by Google in order to track changes to user's Chrome settings and combat malicious software that changes these settings without user permission. Alternatively, we could specify the periods in terms of dates or time points; see Section 5 for an example. Requirements torch 1.7.1 tensorflow-privacy 0.5.1 numpy 1.16.2 Files You will understand the basics on how privacy is preserved in databases, used with machine learning, and deep learning. LATENT enables a data owner to add a randomization layer before data leave the data owners' devices and reach a potentially untrusted machine learning service. Machine learning techniques based on neural networks are achieving remarkable results in a wide variety of domains. News [May-22] Our paper "Differentially Private Multivariate Time Series Forecasting of Aggregated Human Mobility With Deep Learning: Input or Gradient Perturbation?" has been accepted to Neural Computing and Applications and can be accessed . The origin of the Non-IID phenomenon is the personalization of users, who generate the Non-IID data. Currently, my research interests are differential privacy and machine learning privacy and fairness. Although understanding differential privacy requires a mathematical background, this article will cover a very basic overview of the concepts. Di Wang* , Xiangyu Guo* , Chaowen Guan, Shi Li and Jinhui Xu (* equal contribution). PROJECT DESCRIPTION Differential privacy in Deep learning is the process where the concept of Differential Privacy is applied in Deep Learning models. 7, no. 2, pp: 1655-1666 Differential privacy is defined as the distance between the output distribution of an algorithm on neighboring datasets that differ in one entry. We focus on local differential privacy, which we refer to as local privacy. data owner learns a teacher model using its own . Stochastic gradient descent (SGD) is commonly used for FL due to its good empirical performance, but sensitive user information can still be inferred from weight updates shared during FL iterations. Unlike Differential Privacy no trust in a central authority is necessary as noise is added to user inputs locally. In this article we propose two numerical methods based on machine learning and on Picard iterations, respectively, to approximately solve non-local nonlinear PDEs. In particular, we focus on distributed deep learning approaches under the constraint that local data sources of clients (e.g. Federated Learning is a collaborative form of machine learning where the training process is distributed among many users. Learning Objectives. The secure scheme features the properties of randomized response, secure aggregation, and Bloom filter, and endows each client with customized plausible deniability (in terms of local differential privacy) against the position of its desired sub- Definition 3 (Local Differential Privacy (LDP) [ 11]) For an input set X and the set of noisy outputs Y, a randomized algorithm M:X →Y is said to be (ϵ,δ) -LDP if ∀x,x′∈X and ∀y∈Y the following holds, 2.2. On the other hand, when using global differential privacy . The aim of any privacy algorithm is to keep one's private information safe and secured from external attacks. Generally, global differential privacy can lead to more accurate results compared to local differential privacy, while keeping the same privacy level. Considering the fact that the IRS-aided secure communication system has high-dimensional and high-dynamical characteristics according to the system state that is defined in and uncertain CSI, we propose a deep PDS-PER learning based secure beamforming approach, as shown in Fig. Paper: Kai Zheng, Tianle Cai, Weiran Huang, Zhenguo Li, Liwei Wang. xargs -P 20 -n 1 wget -nv < neurips2018.txt.

Private Deep Learning of Medical Data for Hospitals using Federated Learning and Differential privacy. The aim of any privacy algorithm is to keep one's private information safe and secured from external attacks. We remark that LDP does not require defining adjacency. In this talk, I will present our recent work on achieving 1) differential privacy (DP) to ensure privacy of the training data and 2) certified robustness against adversarial examples for deep learning models. Often, the training of models requires large, representative datasets, which may be crowdsourced and contain sensitive information. We design experiments and report preliminary re-sults, proving the system can achieve compression while maintaining an acceptable level of privacy and utility. However, user data is privacy-sensitive, and the centralized storage of user-item graphs may arouse privacy concerns and risk. Local differential privacy. the first practical differentially private deep learning solu-tion for large-scale computer vision that achieves theoreti-cally meaningful DP guarantees (ǫ < 1). 2.1 Local Differential Privacy Differential Privacy (DP) [ 9, 14] aims to protect the privacy of individuals while releasing aggregated information about the database, which prevents membership inference attacks [ 34] by adding randomness to the algorithm outcome. For several years, Google has spearheaded both foundational research on differential privacy as well as the development of practical differential-privacy mechanisms (see for example here and here), with a recent focus on machine learning applications (see this, that, or this research paper).

Locally Differentially Private (LDP) LinUCB is a variant of LinUCB bandit algorithm with local differential privacy guarantee, which can preserve users' personal data with theoretical guarantee. Differential privacy and k-anonymity for machine learning Image by Author — Toronto, Canada User privacy is a rising concern in the nowadays data-driven world. Local Differential Privacy (LDP) is a state-of-the-art approach which allows statistical computations while protecting each individual user's privacy. The origin of the Non-IID phenomenon is the personalization of users, who generate the Non-IID data. ,Besides a git-based version control system, GitHub integrates several social coding features. Abstract: The shuffle model of differential privacy has recently witnessed significant interest as an intermediate setting between the well-studied central and local differential privacy models. Neurocomputing, Volume 399, 25 July 2020, Pages 129-140. Jinyuan Jia and Neil Zhenqiang Gong. This is generally achieved by randomizing the output of the computation through the addition of noise [ Dwork et al., 2014 ]. First, I will present a practical DP training framework for centralized setting with better empirical and theoretical utility (IJCAI'21). This approach requires the output of computation to be more or less unchanged when a single record in the dataset is modified [ Dwork et al., 2006 ]. The !pip install --quiet --upgrade nest-asyncio. Thales (May 2017-October 2017): worked on anomaly detection using deep learning methods, under the supervision of Marc Schoenauer. improved multimodal deep learning with variation of information: .

Paul Sabatier university of Toulouse (November 2018-December 2018): worked on identity testing under local differential privacy constraint, with Jean-Michel Loubes and Beatrice Laurent-Bonneau. Differentially Private User-based Collaborative Filtering Recommendation Based on K-means Clustering Privacy Partitioning: Protecting User Data During the Deep Learning Inference Phase Optimising for privacy loss at early layers suggests pragmatic approach for protecting privacy of prediction inputs without cryptography nor DP. Our key idea is to employ functional perturbation approaches in an original algorithm to preserve DP in both learning new tasks and memorizing acquired tasks in the past. In other words, if a client's privacy budget is $\epsilon$ and the client is selected $T$ times, the client's budget for each noising is $\epsilon / T$. we'll investigate the impacts of the use of anonymization techniques on public medical-related datasets where some private information of patients is present which could allow re . No DP You can run like this: python main.py --dataset mnist --iid --model cnn --epochs 50 --dp_mechanism no_dp Laplace Mechanism This code is based on Simple Composition in DP. Sijing Duan, Deyu Zhang*, Yanbo Zhou, Lingxiang Li, Yaoxue Zhang " JointRec: A Deep-Learning-Based Joint Cloud Video Recommendation Framework for Mobile IoT ",IEEE Internet of Things Journal, vol. The solution to our problem lies in a privacy preserving method called differential privacy. *Equal contribution. Under this crite-rion, the observations remain private from . Define and apply formal notions of privacy, including k-Anonymity and differential privacy. Indeed, there has been a lot of evidences in the litterature ( M.Fredrikson et al.
