Modular DFR: Digital Delayed Feedback Reservoir Model for Enhancing Design Flexibility

no code implementations5 Jul 2023 Sosei Ikeda, Hiromitsu Awano, Takashi Sato

However, digital DFRs emulate analog nonlinear components in the digital domain, resulting in a lack of design flexibility and higher power consumption.

Adaptive Outlier Detection for Power MOSFETs Based on Gaussian Process Regression

no code implementations25 Jan 2022 Kyohei Shimozato, Michihiro Shintani, Takashi Sato

Outlier detection of semiconductor devices is important since manufacturing variation is inherently inevitable.

Accelerating Parameter Extraction of Power MOSFET Models Using Automatic Differentiation

no code implementations22 Oct 2021 Michihiro Shintani, Aoi Ueda, Takashi Sato

The extraction of the model parameters is as important as the development of compact model itself because simulation accuracy is fully determined by the accuracy of the parameters used.

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.

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.
