Secretary of Defense Lloyd Austin said during a briefing on Wednesday that the collision of a Russian jet with a U.S. drone follows a "pattern" of unsafe and risky behavior from Russia. Chairman of the Joint Chiefs of Staff Mark Milley said during a briefing on Wednesday that America doesn't seek "armed conflict" with Russia after the collision of a Russian jet and a U.S. drone On Tuesday, a Russian Su-27 fighter plane collided with a U.S. MQ-9 Reaper drone while traveling over the Black Sea, a U.S. defense official told Fox News. The collision occurred in international airspace while over international waters, with the jet in question being one of two Su-27s flying in tandem. The drone's propeller was damaged, forcing it to be ditched in the Black Sea west of Crimea, the defense official said. Secretary of Defense Lloyd Austin described the incident as a continuation of risky behavior from Russia during Tuesday's press briefing.

BRIAN KENNY: Artificial intelligence or AI for short is certainly creating a lot of buzz these days. And although it may seem like this amorphous thing that's somewhere off in our future, it's already very much in our midst. Navigation apps have turned printed maps into relics. Alexa, knows what you need from the grocery store before you do. Google Nest has the house at just the right temperature before you roll out from under the covers. And this is all great, but now you have to wonder if this intro is written by me or chat GPT. Which raises an important question.

Fox News correspondent Mike Tobin has the latest on the Russia-Ukraine war on'Special Report.' Tensions remain between Russia and the United States after a collision in international airspace. U.S. military command officials said Tuesday that a Russian fighter jet dumped fuel on a U.S. drone over the Black Sea, clipped the drone's propeller and forced it into the water. An MQ-9 Reaper remotely piloted aircraft is parked in a hanger at Creech Air Force Base in Indian Springs, Nevada. Russia is now denying that the aircraft touched one another, and accusing the U.S. of unnecessarily escalating the issue.

Fox News Flash top headlines are here. Check out what's clicking on Foxnews.com. The U.K. and Germany scrambled fighter jets to intercept two Russian aircraft flying near Estonia late Tuesday. The Russian aircraft, a Russian Il-78 Midas refueling plane and an Antonov 148 military transport, approached NATO airspace without contacting Estonian authorities. The incident was the first time the U.K. and Germany have conducted a joint air intercept as part of the NATO treaty.

A robotic shark hungry for plastic is to snap up waste in the River Thames as part of efforts to tackle water pollution. WasteShark is the first marine robot to take London's river by storm, with the ability to'eat' up to 1,100lbs of waste everyday - equivalent to 22,700 plastic bottles. The electric shark has been released in Canary Wharf where it can travel through 3.1 miles (5km) of water before needing a recharge. It comes at a time when plastic waste has almost doubled globally since 2000, with only nine per cent of this successfully recycled, according to an Organisation for Economic Co-operation and Development report. But Britvic-owned Aqua Libra, which is launching the shark, hope to combat this by recycling the collected rubbish wherever possible.

Francis Fukuyama famously said in his 1992 book, The End of History and the Last Man, that history had come to an end circa 1989 with the fall of the Berlin Wall. It announced the end of the Cold War, the collapse of Soviet Russia and, generally, of communism as an economic system, and, correlatively, the unopposed global spread of liberal democracy. One hundred and eighty years before Fukuyama, Hegel had said something similar when he saw Napoleon on horseback riding into the town of Jena in 1806. Napoleon was, for many in those early days, the symbol of the spread of freedom through Europe and against the tyranny of monarchy. There is today the suspicion coming from both Marxists and conservatives alike that the imminent transformation of the labour process, its complete automation through robotics and artificial intelligence (AI), will bring about the end of history.

Youssef Jira, a fresh-faced 18-year-old in a hoodie with a bandana around his head, has big ambitions in a Libyan society where dictatorship and violence has dominated, rather than youthful creativity. Jira is one of a group of young tech fanatics who took part in the Libya Regional Championship for robotics in a suburb of Tripoli this month. Some 20 teams of 12-to-18-year-olds competed in the inclusive event. He wants to encourage other young people to use hi-tech to help modernise the divided and conflict-scarred country. "We want to send a message to the whole of society, because what we've learned has changed us a lot," Jira said, adding that he has gained new skills and learned about teamwork in pursuit of a common goal.

This work proposes a model for continual learning on tasks involving temporal sequences, specifically, human motions. It improves on a recently proposed brain-inspired replay model (BI-R) by building a biologically-inspired conditional temporal variational autoencoder (BI-CTVAE), which instantiates a latent mixture-of-Gaussians for class representation. We investigate a novel continual-learning-to-generate (CL2Gen) scenario where the model generates motion sequences of different classes. The generative accuracy of the model is tested over a set of tasks. The final classification accuracy of BI-CTVAE on a human motion dataset after sequentially learning all action classes is 78%, which is 63% higher than using no-replay, and only 5.4% lower than a state-of-the-art offline trained GRU model.

In this paper, we approach the problem of optimizing blackbox functions over large hybrid search spaces consisting of both combinatorial and continuous parameters. We demonstrate that previous evolutionary algorithms which rely on mutation-based approaches, while flexible over combinatorial spaces, suffer from a curse of dimensionality in high dimensional continuous spaces both theoretically and empirically, which thus limits their scope over hybrid search spaces as well. In order to combat this curse, we propose ES-ENAS, a simple and modular joint optimization procedure combining the class of sample-efficient smoothed gradient techniques, commonly known as Evolutionary Strategies (ES), with combinatorial optimizers in a highly scalable and intuitive way, inspired by the one-shot or supernet paradigm introduced in Efficient Neural Architecture Search (ENAS). By doing so, we achieve significantly more sample efficiency, which we empirically demonstrate over synthetic benchmarks, and are further able to apply ES-ENAS for architecture search over popular RL benchmarks.

InfoMap is a popular approach for detecting densely connected "communities" of nodes in networks. To detect such communities, InfoMap uses random walks and ideas from information theory. Motivated by the dynamics of disease spread on networks, whose nodes may have heterogeneous disease-removal rates, we adapt InfoMap to absorbing random walks. To do this, we use absorption-scaled graphs, in which the edge weights are scaled according to absorption rates, along with Markov time sweeping. One of our adaptations of InfoMap converges to the standard version of InfoMap in the limit in which the node-absorption rates approach $0$. The community structure that we obtain using our adaptations of InfoMap can differ markedly from the community structure that one detects using methods that do not take node-absorption rates into account. Additionally, we demonstrate that the community structure that is induced by local dynamics can have important implications for susceptible-infected-recovered (SIR) dynamics on ring-lattice networks. For example, we find situations in which the outbreak duration is maximized when a moderate number of nodes have large node-absorption rates.
