Knowledge graph embedding (KGE) is a technique for learning continuous embeddings for entities and relations in the knowledge graph.Due to its benefit to a variety of downstream tasks such as knowledge graph completion, question answering and recommendation, KGE has gained significant attention recently. Despite its effectiveness in a benign environment, KGE' robustness to adversarial attacks is not well-studied. Existing attack methods on graph data cannot be directly applied to attack the embeddings of knowledge graph due to its heterogeneity. To fill this gap, we propose a collection of data poisoning attack strategies, which can effectively manipulate the plausibility of arbitrary targeted facts in a knowledge graph by adding or deleting facts on the graph. The effectiveness and efficiency of the proposed attack strategies are verified by extensive evaluations on two widely-used benchmarks.

Governance and independent oversight on the design and implementation of all forms of artificial intelligence (AI) and automation is a cresting wave about to break comprehensively on the field of information technology and computing. If this is a surprise to you, then you may have missed the forest for the trees on a myriad of news stories over the past three to five years. Privacy failures, cybersecurity breeches, unethical choices in decision engines, and biased datasets have repeatedly sprung up as corporations around the world deploy increasing numbers of AIs throughout their organizations. The world, broadly speaking, combined with legislative bodies, regulators, and a dedicated body of academics operating in the field of AI Safety, have been pressing the issue. Now guidelines are taking hold in a practical format.

More than 15,000 Twitter bots used the I Voted hashtag on midterm Election Day in 2018. If you want to make more money, maybe you should become an active Twitter user. It's a hub of highly educated adults who earn higher salaries than the U.S. public overall. Tweeters also tend to have some distinct political views. Pew Research recently set out to find out which voices are loudest on the social media site by sampling accounts held by about 2,700 random U.S. adults.

Facial recognition technology at airports is being called into question after a viral Twitter exchange highlighted the privacy concerns associated with the systems, which are rapidly being deployed by airlines across the U.S. Writer MacKenzie Fegan was startled when her photo was taken by facial recognition cameras as she boarded her international JetBlue flight. Fegan confronted JetBlue about the experience in a lengthy Twitter thread, asking questions about how the system operated, but the airline didn't provide many answers. It comes as the U.S. Department of Homeland Security recently said it hopes to expand use of facial recognition at airports to scan 97 percent of all passengers departing the country by 2023. 'I just boarded an international @JetBlue flight,' Fegan wrote on Twitter. 'Instead of scanning my boarding pass or handing over my passport, I looked into a camera before being allowed down the jet bridge.

The photonic switch is built with more than 50,000 microscopic "light switches" etched into a silicon wafer. Each light switch (small raised squares) directs one of 240 tiny beams of light to either make a right turn when the switch is on, or to pass straight through when the switch is off. Engineers at the University of California, Berkeley have built a new photonic switch that can control the direction of light passing through optical fibers faster and more efficiently than ever. This optical "traffic cop" could one day revolutionize how information travels through data centers and high-performance supercomputers that are used for artificial intelligence and other data-intensive applications. The photonic switch is built with more than 50,000 microscopic "light switches," each of which directs one of 240 tiny beams of light to either make a right turn when the switch is on, or to pass straight through when the switch is off.

The UK government is happy to allow Huawei equipment to form part of the UK's 5G network – just not any of the crucial parts, according to leaked discussions from the National Security Council. The United States and Australia have taken much more hardline approach, with complete bans on using Huawei equipment to form any part of their 5G network. What is all the worry about? According to telecoms firm Qualcomm, 5G mobile internet gives a massive speed boost – at least 10 or 20 times greater – over our current 4G networks. As devices start sharing more and more data, from phones streaming data-rich video to self-driving cars, it's vital to have a speedy connection.

Facebook has said that it expects to be fined up to $5bn by the Federal Trade Commission for privacy violations. The penalty would be a record by the agency against a technology company and a sign that the United States was willing to punish big tech companies. The social network disclosed the amount in its quarterly financial results on Wednesday, saying it estimated a one-time charge of $3bn to $5bn in connection with an "ongoing inquiry" by the commission. Facebook added that "the matter remains unresolved, and there can be no assurance as to the timing or the terms of any final outcome". We'll tell you what's true.

Today, Zipline is officially opening the first of four distribution centers in Ghana, inaugurating a drone-delivery network that will eventually serve 2,000 hospitals and clinics covering 12 million people. Here's what Zipline says in a press release about the new operation: The revolutionary new service will use drones to make on-demand, emergency deliveries of 148 different vaccines, blood products, and life-saving medications. The service will operate 24 hours a day, seven days a week, from 4 distribution centers--each equipped with 30 drones--and deliver to 2,000 health facilities serving 12 million people across the country. Together, all four distribution centers will make up to 600 on-demand delivery flights a day on behalf of the Government of Ghana. Each Zipline distribution center has the capacity to make up to 500 flights per day. Zipline's contract with the government of Ghana is worth US $12.5 million, but there has been significant criticism over the deal from the minority party in the Ghanaian government (backed by the Ghana Medical Association) arguing that funding was urgently needed for basic services rather than for medical drone delivery.

Wing achieved a significant milestone today, becoming the first drone delivery company to receive Air Carrier Certification from the United States Federal Aviation Administration (FAA). This is an important step for the FAA and the drone industry in the United States; the result of years of work to safely integrate drones into the national airspace. We're grateful for the vision of the Administration, the Department of Transportation, and the FAA for creating the Unmanned Aircraft System Integration Pilot Program (UAS IPP) to advance the drone industry in the US. "This is an important step forward for the safe testing and integration of drones into our economy. Safety continues to be our Number One priority as this technology continues to develop and realize its full potential," said U.S. Secretary of Transportation, Elaine L. Chao.
