Chinese carrier strike group, drones operating near Japan, which dispatched aircraft to monitor situation

FOX News

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.


Transformer Based Geocoding

arXiv.org Artificial Intelligence

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.


2022 military hardware to remember

FOX News

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.


22 Things That Made the World a Better Place in 2022

WIRED

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 Says Repelled Russia Nighttime Drone Attack

International Business Times

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.


Web scraping and text analysis in R and GGplot2 – A.Z. Andis Arietta

#artificialintelligence

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.



A Deep Learning Method for Real-time Bias Correction of Wind Field Forecasts in the Western North Pacific

arXiv.org Artificial Intelligence

Forecasts by the European Centre for Medium-Range Weather Forecasts (ECMWF; EC for short) can provide a basis for the establishment of maritime-disaster warning systems, but they contain some systematic biases.The fifth-generation EC atmospheric reanalysis (ERA5) data have high accuracy, but are delayed by about 5 days. To overcome this issue, a spatiotemporal deep-learning method could be used for nonlinear mapping between EC and ERA5 data, which would improve the quality of EC wind forecast data in real time. In this study, we developed the Multi-Task-Double Encoder Trajectory Gated Recurrent Unit (MT-DETrajGRU) model, which uses an improved double-encoder forecaster architecture to model the spatiotemporal sequence of the U and V components of the wind field; we designed a multi-task learning loss function to correct wind speed and wind direction simultaneously using only one model. The study area was the western North Pacific (WNP), and real-time rolling bias corrections were made for 10-day wind-field forecasts released by the EC between December 2020 and November 2021, divided into four seasons. Compared with the original EC forecasts, after correction using the MT-DETrajGRU model the wind speed and wind direction biases in the four seasons were reduced by 8-11% and 9-14%, respectively. In addition, the proposed method modelled the data uniformly under different weather conditions. The correction performance under normal and typhoon conditions was comparable, indicating that the data-driven mode constructed here is robust and generalizable.


On the road in San Francisco, riding in a driverless taxi

Al Jazeera

Perched on the edge of a curb, squinting down the length of Market Street in the US city of San Francisco, I find myself twitchily tapping my phone, only to wince as the time ticks away. And up the Market Street rail line rumbles my deliverance: a 1928 wood-panelled tram in green-and-white trim. Oh, the irony: I'm headed to test out one of the city's newest transportation options while creaking down the road on one of its oldest. San Francisco has long been a hub for transportation innovation. It was here that the first cable car system was put into use.


Tesla behind eight-vehicle crash was in 'full self-driving' mode, says driver

The Guardian

The driver of a 2021 Tesla Model S told California authorities the vehicle was in "full self-driving mode" when the technology malfunctioned, causing an eight-vehicle crash on the San Francisco Bay bridge last month. The crash on Thanksgiving Day resulted in two juveniles being transported to hospital and led to lengthy delays on the bridge. The incident was made public in a police report on Wednesday. It is the latest in a series of accidents blamed on Tesla technology. The electric automaker's chief executive, Elon Musk, has heavily promoted "Full Self-Driving" (FSD) software, sold as $15,000 add-on to Tesla vehicles, but it faces legal, regulatory and public scrutiny.
