Federated Empirical Risk Minimization via Second-Order Method

no code implementations27 May 2023 Song Bian, Zhao Song, Junze Yin

Many convex optimization problems with important applications in machine learning are formulated as empirical risk minimization (ERM).

Certifiable Robustness for Naive Bayes Classifiers

no code implementations8 Mar 2023 Song Bian, Xiating Ouyang, Zhiwei Fan, Paraschos Koutris

We present (i) a linear time algorithm in the number of entries in the dataset that decides whether a test point is certifiably robust for NBC, (ii) an algorithm that counts for each label, the number of cleaned datasets on which the NBC can be trained to predict that label, and (iii) an efficient optimal algorithm that poisons a clean dataset by inserting the minimum number of missing values such that a test point is not certifiably robust for NBC.

Virtual Secure Platform: A Five-Stage Pipeline Processor over TFHE

1 code implementation19 Oct 2020 Kotaro Matsuoka, Ryotaro Banno, Naoki Matsumoto, Takashi Sato, Song Bian

Our experiments show that both the pipelined architecture and the CMUX Memory technique are effective in improving the performance of the proposed processor.

FedNNNN: Norm-Normalized Neural Network Aggregation for Fast and Accurate Federated Learning

no code implementations11 Aug 2020 Kenta Nagura, Song Bian, Takashi Sato

In this work, we find out that averaging models from different clients significantly diminishes the norm of the update vectors, resulting in slow learning rate and low prediction accuracy.

AutoPrivacy: Automated Layer-wise Parameter Selection for Secure Neural Network Inference

no code implementations NeurIPS 2020 Qian Lou, Song Bian, Lei Jiang

Prior HPPNNs over-pessimistically select huge HE parameters to maintain large noise budgets, since they use the same set of HE parameters for an entire network and ignore the error tolerance capability of a network.

ENSEI: Efficient Secure Inference via Frequency-Domain Homomorphic Convolution for Privacy-Preserving Visual Recognition

no code implementations CVPR 2020 Song Bian, Tianchen Wang, Masayuki Hiromoto, Yiyu Shi, Takashi Sato

In this work, we propose ENSEI, a secure inference (SI) framework based on the frequency-domain secure convolution (FDSC) protocol for the efficient execution of privacy-preserving visual recognition.

NASS: Optimizing Secure Inference via Neural Architecture Search

no code implementations30 Jan 2020 Song Bian, Weiwen Jiang, Qing Lu, Yiyu Shi, Takashi Sato

Due to increasing privacy concerns, neural network (NN) based secure inference (SI) schemes that simultaneously hide the client inputs and server models attract major research interests.

Are Powerful Graph Neural Nets Necessary? A Dissection on Graph Classification

1 code implementation11 May 2019 Ting Chen, Song Bian, Yizhou Sun

In this work, we propose a dissection of GNNs on graph classification into two parts: 1) the graph filtering, where graph-based neighbor aggregations are performed, and 2) the set function, where a set of hidden node features are composed for prediction.
