TpopT: Efficient Trainable Template Optimization on Low-Dimensional Manifolds

no code implementations16 Oct 2023 Jingkai Yan, Shiyu Wang, Xinyu Rain Wei, Jimmy Wang, Zsuzsanna Márka, Szabolcs Márka, John Wright

In this work, we study TpopT (TemPlate OPTimization) as an alternative scalable framework for detecting low-dimensional families of signals which maintains high interpretability.

Boosting the Efficiency of Parametric Detection with Hierarchical Neural Networks

no code implementations23 Jul 2022 Jingkai Yan, Robert Colgan, John Wright, Zsuzsa Márka, Imre Bartos, Szabolcs Márka

Various approaches have been proposed for improving the efficiency of the detection scheme, with hierarchical matched filtering being an important strategy.

Resource-Efficient Invariant Networks: Exponential Gains by Unrolled Optimization

1 code implementation9 Mar 2022 Sam Buchanan, Jingkai Yan, Ellie Haber, John Wright

Achieving invariance to nuisance transformations is a fundamental challenge in the construction of robust and reliable vision systems.

Detecting and Diagnosing Terrestrial Gravitational-Wave Mimics Through Feature Learning

no code implementations9 Mar 2022 Robert E. Colgan, Zsuzsa Márka, Jingkai Yan, Imre Bartos, John N. Wright, Szabolcs Márka

As engineered systems grow in complexity, there is an increasing need for automatic methods that can detect, diagnose, and even correct transient anomalies that inevitably arise and can be difficult or impossible to diagnose and fix manually.

Architectural Optimization and Feature Learning for High-Dimensional Time Series Datasets

no code implementations27 Feb 2022 Robert E. Colgan, Jingkai Yan, Zsuzsa Márka, Imre Bartos, Szabolcs Márka, John N. Wright

As our ability to sense increases, we are experiencing a transition from data-poor problems, in which the central issue is a lack of relevant data, to data-rich problems, in which the central issue is to identify a few relevant features in a sea of observations.

Square Root Principal Component Pursuit: Tuning-Free Noisy Robust Matrix Recovery

no code implementations NeurIPS 2021 Junhui Zhang, Jingkai Yan, John Wright

We show that a single, universal choice of the regularization parameter suffices to achieve reconstruction error proportional to the (a priori unknown) noise level.

Generalized Approach to Matched Filtering using Neural Networks

no code implementations8 Apr 2021 Jingkai Yan, Mariam Avagyan, Robert E. Colgan, Doğa Veske, Imre Bartos, John Wright, Zsuzsa Márka, Szabolcs Márka

Moreover, we show that the proposed neural network architecture can outperform matched filtering, both with or without knowledge of a prior on the parameter distribution.
