Fast Multivariate Spatio-temporal Analysis via Low Rank Tensor Learning Mohammad T aha Bahadori
Accurate and efficient analysis of multivariate spatio-temporal data is critical in climatology, geology, and sociology applications. Existing models usually assume simple inter-dependence among variables, space, and time, and are computationally expensive. We propose a unified low rank tensor learning framework for multivariate spatio-temporal analysis, which can conveniently incorporate different properties in spatio-temporal data, such as spatial clustering and shared structure among variables. We demonstrate how the general framework can be applied to cokriging and forecasting tasks, and develop an efficient greedy algorithm to solve the resulting optimization problem with convergence guarantee. We conduct experiments on both synthetic datasets and real application datasets to demonstrate that our method is not only significantly faster than existing methods but also achieves lower estimation error.

Captain of tanker linked to Russian 'shadow fleet' charged in France
Captain of tanker linked to Russian'shadow fleet' charged in France The captain of an oil tanker believed to be part of Russia's shadow fleet of vessels used to evade sanctions has been charged by French authorities. The Chinese national was handed one count of refusing to follow instructions from the French navy and told to attend a court hearing in the northern coastal city of Brest next February. The Boracay left Russia last month and was off the coast of Denmark when unidentified drones forced the temporary closure of several airports last week. The tanker was earlier boarded by French soldiers because it was on a list of vessels subject to EU sanctions for carrying Russian oil exports. Russian President Vladimir Putin called France's actions piracy.
U-20 World Cup Who would you play for?
Game Theory U-20 World Cup Who would you play for? FIFA calls the U-20 World Cup "the tournament of tomorrow's superstars" - it's also the first fork in the road for these young players. At youth level they can still choose which country to play for. Samantha Johnson asks where should your loyalty lie? The country you're born in, or the country of your heritage?
UN warns of potential 'ethnically driven' atrocities in Sudan's el-Fasher
UN warns of potential'ethnically driven' atrocities in Sudan's el-Fasher At least 91 people have been killed in Sudan's besieged city of el-Fasher in attacks by the paramilitary Rapid Support Forces (RSF) over 10 days last month, the United Nations says. The attacks took place during intensified fighting between the RSF and Sudan's army around the city, the largest urban centre in the Darfur region that remains under the control of the military and its allies, known as the Joint Forces. UN rights chief Volker Turk said on Thursday that the city's Daraja Oula neighbourhood was repeatedly attacked and subjected to RSF artillery shelling, drone strikes and ground incursions from September 19 to 29. He called for urgent action to prevent "large-scale, ethnically driven attacks and atrocities in el-Fasher." He said "atrocities are not inevitable", adding that "they can be averted if all actors take concrete action to uphold international law, demand respect for civilian life and property, and prevent the continued commission of atrocity crimes".
Cross-Domain Matching for Bag-of-Words Data via Kernel Embeddings of Latent Distributions
Yuya Yoshikawa, Tomoharu Iwata, Hiroshi Sawada, Takeshi Yamada
We propose a kernel-based method for finding matching between instances across different domains, such as multilingual documents and images with annotations. Each instance is assumed to be represented as a multiset of features, e.g., a bag-of-words representation for documents. The major difficulty in finding cross-domain relationships is that the similarity between instances in different domains cannot be directly measured. To overcome this difficulty, the proposed method embeds all the features of different domains in a shared latent space, and regards each instance as a distribution of its own features in the shared latent space. To represent the distributions efficiently and nonparametrically, we employ the framework of the kernel embeddings of distributions. The embedding is estimated so as to minimize the difference between distributions of paired instances while keeping unpaired instances apart. In our experiments, we show that the proposed method can achieve high performance on finding correspondence between multi-lingual Wikipedia articles, between documents and tags, and between images and tags.

Tesla sales jump as buyers scramble before EV tax credit expires
Tesla sales have surged in the third quarter as buyers in the United States rushed to take advantage of electric vehicle (EV) tax credits that were eliminated under President Donald Trump's sweeping tax bill passed this year. On Thursday, the automaker reported a 7.4 percent increase in sales compared with the same period last year as demand was driven by customers looking to buy before the credits officially expired at the end of September. Tesla also delivered 481,166 units of its Model 3 compact sedan and Model Y crossover in the quarter, well above Wall Street expectations. The Elon Musk-led carmaker frequently talked up the expiry of the tax credits, using it alongside discounts and financing deals to spur sales and leases of its EVs. Investors are worried because sales are now expected to slump as the $7,500 federal tax credit disappears.
