What's the Difference? The potential for Convolutional Neural Networks for transient detection without template subtraction

1 code implementation14 Mar 2022 Tatiana Acero-Cuellar, Federica Bianco, Gregory Dobler, Masao Sako, Helen Qu, The LSST Dark Energy Science Collaboration

We present a study of the potential for Convolutional Neural Networks (CNNs) to enable separation of astrophysical transients from image artifacts, a task known as "real-bogus" classification without requiring a template subtracted (or difference) image which requires a computationally expensive process to generate, involving image matching on small spatial scales in large volumes of data.

Do cities have a unique magnetic pulse?

no code implementations12 Feb 2022 Vincent Dumont, Trevor A. Bowen, Roger Roglans, Gregory Dobler, Mohit S. Sharma, Andy Karpf, Stuart D. Bale, Arne Wickenbrock, Elena Zhivun, Tom Kornack, Jonathan S. Wurtele, Dmitry Budker

We present a comparative analysis of urban magnetic fields between two American cities: Berkeley (California) and Brooklyn Borough of New York City (New York).

Patterns of Urban Foot Traffic Dynamics

no code implementations6 Oct 2019 Gregory Dobler, Jordan Vani, Trang Tran Linh Dam

Projecting all days in our study period onto the weekday/weekend phase space (by regressing against the average weekday and weekend day) we find that Friday foot traffic can be represented as a mixture of both the 3-peak weekday structure and non-peaked weekend structure.

TrackNet: Simultaneous Object Detection and Tracking and Its Application in Traffic Video Analysis

no code implementations4 Feb 2019 Chenge Li, Gregory Dobler, Xin Feng, Yao Wang

We propose a novel network structure named trackNet that can directly detect a 3D tube enclosing a moving object in a video segment by extending the faster R-CNN framework.
