Stochastic evolution equations describing the dynamics of systems under the influence of both deterministic and stochastic forces are prevalent in all fields of science. Yet, identifying these systems from sparse-in-time observations remains still a challenging endeavour. Existing approaches focus either on the temporal structure of the observations by relying on conditional expectations, discarding thereby information ingrained in the geometry of the system's invariant density; or employ geometric approximations of the invariant density, which are nevertheless restricted to systems with conservative forces. Here we propose a method that reconciles these two paradigms. We introduce a new data-driven path augmentation scheme that takes the local observation geometry into account. By employing non-parametric inference on the augmented paths, we can efficiently identify the deterministic driving forces of the underlying system for systems observed at low sampling rates.

The recognition or understanding of the scenes observed with a SAR system requires a broader range of cues, beyond the spatial context. These encompass but are not limited to: imaging geometry, imaging mode, properties of the Fourier spectrum of the images or the behavior of the polarimetric signatures. In this paper, we propose a change of paradigm for explainability in data science for the case of Synthetic Aperture Radar (SAR) data to ground the explainable AI for SAR. It aims to use explainable data transformations based on well-established models to generate inputs for AI methods, to provide knowledgeable feedback for training process, and to learn or improve high-complexity unknown or un-formalized models from the data. At first, we introduce a representation of the SAR system with physical layers: i) instrument and platform, ii) imaging formation, iii) scattering signatures and objects, that can be integrated with an AI model for hybrid modeling. Successively, some illustrative examples are presented to demonstrate how to achieve hybrid modeling for SAR image understanding. The perspective of trustworthy model and supplementary explanations are discussed later. Finally, we draw the conclusion and we deem the proposed concept has applicability to the entire class of coherent imaging sensors and other computational imaging systems.

Former Assistant Secretary of State Robert Charles joined'Fox & Friends First' to discuss the surge of COVID cases in China and Kim Jong Un vowing to bolster North Korea's nuclear weapons. Chinese drones were operating near Japan this week, prompting Japanese defense officials to dispatch aircraft and naval ships to monitor the situation, according to media reports. The unmanned aerial vehicles (UAVs) have been transiting the Miyako Strait from the East China Sea into the Pacific and returning the same way, USNI News reported. The Miyako Strait is a waterway between Miyako Island and Okinawa. Meanwhile, Chinese warships were also seen in the East China Sea after two weeks near the Philippines.

In this paper, we formulate the problem of predicting a geolocation from free text as a sequence-to-sequence problem. Using this formulation, we obtain a geocoding model by training a T5 encoder-decoder transformer model using free text as an input and geolocation as an output. The geocoding model was trained on geo-tagged wikidump data with adaptive cell partitioning for the geolocation representation. All of the code including Rest-based application, dataset and model checkpoints used in this work are publicly available.

Rep. Rob Wittman, R-Va., joins'Fox News Live' to react to the United States Air Force's unveiling of its new B-21 raider stealth bomber, named'The Raider' for Jimmy Doolittle's famous bombing raid on Japan in WW2. With the launch of the Air Force's hypersonic missile off the coast of California earlier this month, the Navy's development of water-based drones over the summer and the recent unveiling of the B-21 Raiders, the U.S. military has made major technological advancements over the past year. The military unveiled the U.S. Air Force B-21 Raider in Palmdale, California. The B-21 Raider is the first new American bomber aircraft in more than three decades. In an email to Fox News Digital, a spokesperson confirmed the Air Force would transition its three-bomber fleet to a two-bomber fleet of B-21s and modernized B-52s.

It seemed as if the world was plunging from one crisis to another this year. Just as most countries broke free from the shackles of the pandemic, the horror of war returned to Europe, millions around the world suffered at the hands of extreme weather, and the double pain of energy shortages and inflation arrived. Here's our rundown of the best news to come out of 2022. More than one-fifth of all electricity in the US now comes from hydropower, wind, and solar, meaning that renewables have narrowly overtaken coal and nuclear, which make up 20 percent and 19 percent of the energy mix respectively. The only other year this was the case was 2020--but back then overall power generation was reduced due to the pandemic.

Ukraine said Friday it repelled a nighttime drone attack from Russia, a day after Moscow launched a new wave of missile strikes in the run-up to New Year celebrations. The attacks came 10 months into Moscow's invasion of Ukraine. In recent months Russian strikes have targeted the energy grid, leaving millions in the cold in the middle of winter. Ukraine's air force said on Friday morning that Russia attacked Ukraine overnight using "Iranian-made kamikaze drones". A total of 16 drones were launched from the southeastern and northern directions and they were "all" destroyed by Ukraine's air defence, it said.

I recently needed to learn text mining for a project at work. I generally learn more quickly with a real-world project. So, I turned to a topic I love: Wilderness, to see how I could apply the skills of text scrubbing and natural language processing. You can clone my Git repo for the project or follow along in the post below. The first portion of this post will cover web scraping, then text mining, and finally analysis and visualization.
