A zero-inflated gamma model for deconvolved calcium imaging traces

1 code implementation5 Jun 2020 Xue-Xin Wei, Ding Zhou, Andres Grosmark, Zaki Ajabi, Fraser Sparks, Pengcheng Zhou, Mark Brandon, Attila Losonczy, Liam Paninski

However, statistical modeling of deconvolved calcium signals (i. e., the estimated activity extracted by a pre-processing pipeline) is just as critical for interpreting calcium measurements, and for incorporating these observations into downstream probabilistic encoding and decoding models.

Short and Sparse Deconvolution --- A Geometric Approach

1 code implementation ICLR 2020 Yenson Lau, Qing Qu, Han-Wen Kuo, Pengcheng Zhou, Yuqian Zhang, John Wright

Short-and-sparse deconvolution (SaSD) is the problem of extracting localized, recurring motifs in signals with spatial or temporal structure.

Regression via Arbitrary Quantile Modeling

1 code implementation13 Nov 2019 Faen Zhang, Xinyu Fan, Hui Xu, Pengcheng Zhou, Yujian He, Junlong Liu

In the regression problem, L1 and L2 are the most commonly used loss functions, which produce mean predictions with different biases.

Short-and-Sparse Deconvolution -- A Geometric Approach

1 code implementation28 Aug 2019 Yenson Lau, Qing Qu, Han-Wen Kuo, Pengcheng Zhou, Yuqian Zhang, John Wright

This paper is motivated by recent theoretical advances, which characterize the optimization landscape of a particular nonconvex formulation of SaSD.

Efficient and accurate extraction of in vivo calcium signals from microendoscopic video data

8 code implementations24 May 2016 Pengcheng Zhou, Shanna L. Resendez, Jose Rodriguez-Romaguera, Jessica C. Jimenez, Shay Q. Neufeld, Garret D. Stuber, Rene Hen, Mazen A. Kheirbek, Bernardo L. Sabatini, Robert E. Kass, Liam Paninski

In vivo calcium imaging through microscopes has enabled deep brain imaging of previously inaccessible neuronal populations within the brains of freely moving subjects.

False discovery rate regression: an application to neural synchrony detection in primary visual cortex

1 code implementation12 Jul 2013 James G. Scott, Ryan C. Kelly, Matthew A. Smith, Pengcheng Zhou, Robert E. Kass

But this may be inappropriate for many of today's large-scale screening problems, where auxiliary information about each test is often available, and where a combined analysis can lead to poorly calibrated error rates within different subsets of the experiment.
