Conservative Flows: A New Paradigm of Generative Models
Eshed Gal, Md Shahriar Rahim Siddiqui, Moshe Eliasof +1
Modern generative modeling is dominated by transport from a noise prior to data. We propose an alternative paradigm in which generation is performed by a discrete stochastic dynami…
Preconditioned Flow Matching
Shadab Ahamed, Eshed Gal, Md Shahriar Rahim Siddiqui +3
Flow matching (FM) learns vector fields by regressing stochastic velocity targets along intermediate distributions . We identify a geometric optimization bottleneck in this re…
Graph Flow Matching: Enhancing Image Generation with Neighbor-Aware Flow Fields
Md Shahriar Rahim Siddiqui, Moshe Eliasof, Eldad Haber
Flow matching casts sample generation as learning a continuous-time velocity field that transports noise to data. Existing flow matching networks typically predict each point's vel…
Iterative Flow Matching: Path Correction and Gradual Refinement for Enhanced Generative Modeling
Eldad Haber, Shadab Ahamed, Md. Shahriar Rahim Siddiqui +2
Generative models for image generation are now commonly used for a wide variety of applications, ranging from guided image generation for entertainment to solving inverse problems.…
Learning Regularization for Graph Inverse Problems
Moshe Eliasof, Md Shahriar Rahim Siddiqui, Carola-Bibiane Schönlieb +1
In recent years, Graph Neural Networks (GNNs) have been utilized for various applications ranging from drug discovery to network design and social networks. In many applications, i…
Deep Optimal Experimental Design for Parameter Estimation Problems
Md Shahriar Rahim Siddiqui, Arman Rahmim, Eldad Haber
Optimal experimental design is a well studied field in applied science and engineering. Techniques for estimating such a design are commonly used within the framework of parameter…
Radio impulsive events in quiet solar corona and Axion Quark Nugget Dark Matter
Shuailiang Ge, Md Shahriar Rahim Siddiqui, Ludovic Van Waerbeke +1
The Murchison Widefield Array (MWA) recorded \cite{Mondal-2020} impulsive radio events in the quiet solar corona at frequencies 98, 120, 132, and 160 MHz. We propose that these rad…
X-ray annual modulation observed by XMM-Newton and Axion Quark Nugget Dark Matter
Shuailiang Ge, Hikari Rachmat, Md Shahriar Rahim Siddiqui +2
The XMM-Newton observatory shows evidence, with a 11 confidence level, for seasonal variation of the X-ray background in the near-Earth environment in the 2-6 keV energy range (…
Axion Quark Nugget Dark Matter: Time Modulations and Amplifications
Xunyu Liang, Alexander Mead, Md Shahriar Rahim Siddiqui +2
We study the new mechanism of the axion production suggested recently in [1,2]. This mechanism is based on the so-called Axion Quark Nugget (AQN) dark matter model, which was origi…
Gravitationally trapped axions on Earth
Kyle Lawson, Xunyu Liang, Alexander Mead +3
We advocate for the idea that there is a fundamentally new mechanism for axion production on Earth, as recently suggested in Fischer et al. (2018) and Liang & Zhitnitsky (2018). We…
