Scaling Private Deep Learning with Low-Rank and Sparse Gradients

no code implementations6 Jul 2022 Ryuichi Ito, Seng Pei Liew, Tsubasa Takahashi, Yuya Sasaki, Makoto Onizuka

Applying Differentially Private Stochastic Gradient Descent (DPSGD) to training modern, large-scale neural networks such as transformer-based models is a challenging task, as the magnitude of noise added to the gradients at each iteration scales with model dimension, hindering the learning capability significantly.

Shuffle Gaussian Mechanism for Differential Privacy

1 code implementation20 Jun 2022 Seng Pei Liew, Tsubasa Takahashi

We study Gaussian mechanism in the shuffle model of differential privacy (DP).

Privacy Amplification via Shuffled Check-Ins

1 code implementation7 Jun 2022 Seng Pei Liew, Satoshi Hasegawa, Tsubasa Takahashi

We study a protocol for distributed computation called shuffled check-in, which achieves strong privacy guarantees without requiring any further trust assumptions beyond a trusted shuffler.

Network Shuffling: Privacy Amplification via Random Walks

no code implementations8 Apr 2022 Seng Pei Liew, Tsubasa Takahashi, Shun Takagi, Fumiyuki Kato, Yang Cao, Masatoshi Yoshikawa

However, introducing a centralized entity to the originally local privacy model loses some appeals of not having any centralized entity as in local differential privacy.

Universal Adversarial Spoofing Attacks against Face Recognition

no code implementations2 Oct 2021 Takuma Amada, Seng Pei Liew, Kazuya Kakizaki, Toshinori Araki

We assess the vulnerabilities of deep face recognition systems for images that falsify/spoof multiple identities simultaneously.

PEARL: Data Synthesis via Private Embeddings and Adversarial Reconstruction Learning

1 code implementation ICLR 2022 Seng Pei Liew, Tsubasa Takahashi, Michihiko Ueno

We propose a new framework of synthesizing data using deep generative models in a differentially private manner.

Advances in Multi-Variate Analysis Methods for New Physics Searches at the Large Hadron Collider

1 code implementation16 May 2021 Anna Stakia, Tommaso Dorigo, Giovanni Banelli, Daniela Bortoletto, Alessandro Casa, Pablo de Castro, Christophe Delaere, Julien Donini, Livio Finos, Michele Gallinaro, Andrea Giammanco, Alexander Held, Fabricio Jiménez Morales, Grzegorz Kotkowski, Seng Pei Liew, Fabio Maltoni, Giovanna Menardi, Ioanna Papavergou, Alessia Saggio, Bruno Scarpa, Giles C. Strong, Cecilia Tosciri, João Varela, Pietro Vischia, Andreas Weiler

Between the years 2015 and 2019, members of the Horizon 2020-funded Innovative Training Network named "AMVA4NewPhysics" studied the customization and application of advanced multivariate analysis methods and statistical learning tools to high-energy physics problems, as well as developed entirely new ones.

FaceLeaks: Inference Attacks against Transfer Learning Models via Black-box Queries

no code implementations27 Oct 2020 Seng Pei Liew, Tsubasa Takahashi

We investigate if one can leak or infer such private information without interacting with the teacher model directly.
