Learnable Group Transform For Time-Series

1 code implementation ICML 2020 Romain Cosentino, Behnaam Aazhang

This framework allows us to generalize classical time-frequency transformations such as the Wavelet Transform, and to efficiently learn the representation of signals.

e-G2C: A 0.14-to-8.31 $μ$J/Inference NN-based Processor with Continuous On-chip Adaptation for Anomaly Detection and ECG Conversion from EGM

no code implementations24 Jul 2022 Yang Zhao, Yongan Zhang, Yonggan Fu, Xu Ouyang, Cheng Wan, Shang Wu, Anton Banta, Mathews M. John, Allison Post, Mehdi Razavi, Joseph Cavallaro, Behnaam Aazhang, Yingyan Lin

This work presents the first silicon-validated dedicated EGM-to-ECG (G2C) processor, dubbed e-G2C, featuring continuous lightweight anomaly detection, event-driven coarse/precise conversion, and on-chip adaptation.

Spatial Transformer K-Means

no code implementations16 Feb 2022 Romain Cosentino, Randall Balestriero, Yanis Bahroun, Anirvan Sengupta, Richard Baraniuk, Behnaam Aazhang

This enables (i) the reduction of intrinsic nuisances associated with the data, reducing the complexity of the clustering task and increasing performances and producing state-of-the-art results, (ii) clustering in the input space of the data, leading to a fully interpretable clustering algorithm, and (iii) the benefit of convergence guarantees.

RT-RCG: Neural Network and Accelerator Search Towards Effective and Real-time ECG Reconstruction from Intracardiac Electrograms

no code implementations4 Nov 2021 Yongan Zhang, Anton Banta, Yonggan Fu, Mathews M. John, Allison Post, Mehdi Razavi, Joseph Cavallaro, Behnaam Aazhang, Yingyan Lin

To close this gap and make a heuristic step towards real-time critical intervention in instant response to irregular and infrequent ventricular rhythms, we propose a new framework dubbed RT-RCG to automatically search for (1) efficient Deep Neural Network (DNN) structures and then (2)corresponding accelerators, to enable Real-Time and high-quality Reconstruction of ECG signals from EGM signals.

Deep Autoencoders: From Understanding to Generalization Guarantees

no code implementations20 Sep 2020 Romain Cosentino, Randall Balestriero, Richard Baraniuk, Behnaam Aazhang

Our regularizations leverage recent advances in the group of transformation learning to enable AEs to better approximate the data manifold without explicitly defining the group underlying the manifold.

The Geometry of Deep Networks: Power Diagram Subdivision

1 code implementation NeurIPS 2019 Randall Balestriero, Romain Cosentino, Behnaam Aazhang, Richard Baraniuk

The subdivision process constrains the affine maps on the (exponentially many) power diagram regions to greatly reduce their complexity.

Robust Unsupervised Transient Detection With Invariant Representation based on the Scattering Network

no code implementations23 Nov 2016 Randall Balestriero, Behnaam Aazhang

We present a sparse and invariant representation with low asymptotic complexity for robust unsupervised transient and onset zone detection in noisy environments.
