In this paper, we propose FFCI, a framework for fine-grained summarization evaluation that comprises four elements: faithfulness (degree of factual consistency with the source), focus (precision of summary content relative to the reference), coverage (recall of summary content relative to the reference), and inter-sentential coherence (document fluency between adjacent sentences). We construct a novel dataset for focus, coverage, and inter-sentential coherence, and develop automatic methods for evaluating each of the four dimensions of FFCI based on cross-comparison of evaluation metrics and model-based evaluation methods, including question answering (QA) approaches, semantic textual similarity (STS), next-sentence prediction (NSP), and scores derived from 19 pre-trained language models. We then apply the developed metrics in evaluating a broad range of summarization models across two datasets, with some surprising findings.

Phishing attacks are cyber-attacks through which criminals trick users into sending them money and sensitive information, or into installing malware on their computer, by sending them deceptive emails or messages. As these attacks have become increasingly widespread, developers have been trying to develop more advanced tools to detect them and protect potential victims. Researchers at Monash University and CSIRO's Data61 in Australia have recently developed a machine learning-based approach that could help users to identify phishing emails, so that they don't inadvertently install malware or send sensitive data to cyber-criminals. This model was introduced in a paper pre-published on arXiv and set to be presented at AsiaCCS 2022, a cyber-security conference. "We have identified a gap in current phishing research, namely realizing that existing literature focuses on rigorous'black and white' methods to classify whether something is a phishing email or not," Tingmin (Tina) Wu, one of the researchers who carried out the study, told TechXplore.

This slow pace frustrated many fans of the games -- myself included. We know the backstory of Catherine Halsey (Natascha McElhone) and her use of kidnapped children for the Spartan soldier program that created the Master Chief. Except in this series, Master Chief is kept in the dark of his adopted mother and creator's sinister machinations, and the United Nations Space Command, humanity's authoritarian military power, is also unaware of Halsey's most dehumanizing, illegal experiments. His discovery of this scheme plays out rather slowly, and given that lack of action, the dramatic tension felt repetitive to knowing fans of the games' story.

Severe wildfires, raging storms and other extreme weather conditions are all indications that the climate is changing and not for the better. Earlier this month, the United Nations Intergovernmental Panel on Climate Change released its sixth report on the assessment of global climate conditions. The report looks at environments that are growing warmer, rising sea levels and species becoming extinct. The warning is clear: Something must be done to save the climate. But some have attempted to use AI to combat climate change.

AI will close the gap with human capabilities in the next few decades and surpass them in many domains. This will lead to a reduced need for astronauts, giving mankind a choice to "ride-along" as adventurers or stay at home on the couch watching robots boldly go where no man has gone before. This is the prediction of science writer Donald Goldsmith and astronomer Martin Rees in their new book The End of Astronauts [1]. However, while it's likely that we'll see an increase in AI space missions, humans' obsessive desire for exploration means that we're not likely to see the complete demise of astronauts. AI has come a long way since Alan Turing's mid-1920s vision of "Intelligent Machinery," and it's improving exponentially.

The US Postal Service is facing more than just stern warnings over its decision to buy mostly gas-powered mail delivery trucks. Environmental activist groups (including the Center for Biological Diversity and the Sierra Club) and 16 states have filed lawsuits in California and New York State to challenge the Postal Service's Next Generation Delivery Vehicle purchasing decision. They argue the USPS's environmental review was flawed and illegal, ignoring the "decades of pollution" the combustion-engine trucks would produce. The USPS allegedly violated the National Environmental Policy Act by committing to buy 165,000 delivery vehicles (just 10 percent of them electric) without first conducting a "lawful" environmental review. The service only started its review six months after it had signed a contract, according to the California lawsuit.

The subject of AI has long been on the lips of business leaders. But rather than simply being a subject of aspirational keynotes, it has moved from theory to practice in businesses. Susana Duran is Vice President of Digital Experiences at Sage. The exponential boom in data means businesses have a huge opportunity on their hands to gain real-time, tailored insights to enhance business agility. However, they also risk being swamped by data if they don't embrace intelligent tech soon.

We are excited to bring Transform 2022 back in-person July 19 and virtually July 20 - 28. Join AI and data leaders for insightful talks and exciting networking opportunities. Gaps in cybersecurity tech stacks, especially in endpoint security and patch management, are increasingly leaving enterprises vulnerable to attacks. CISOs are focusing on how to drive new digital revenue strategies while reducing risk and protecting virtual workforces amidst the various threats. From cybercriminal gangs trying to recruit AI engineers, to state-funded Advanced Persistent Threat (APT) networks capable of simultaneously launching attacks across multiple attack vectors, cybercriminals are getting smarter all the time. Studies of job ads on the dark web show that those who know how to breach web services, have AI-based hacking skills and can capture privileged access credentials are the most in-demand.

MARSEILLE, France and PROVIDENCE, R.I., April 27, 2022 (GLOBE NEWSWIRE) -- Volta Medical, a pioneering medtech startup advancing novel artificial intelligence (AI) algorithms to treat cardiac arrhythmias, today announced it will participate at Heart Rhythm 2022, where Volta VX1 digital AI companion technology will be featured in several venues, including a poster session, podium presentation, Rhythm Theater program and the Volta exhibit booth. VX1 is a machine and deep learning-based algorithm designed to assist operators in the real-time manual annotation of 3D anatomical and electrical maps of the human atria during atrial fibrillation (AF) or atrial tachycardia. It is the first FDA cleared AI-based tool in interventional cardiac electrophysiology (EP). On Friday, April 29, VX1 will be highlighted in two scientific sessions: session DH-202, "Machine Learning Applications for Arrhythmia Detection and Treatment" from 10:30-11:30 a.m. Volta's Rhythm Theater presentation, "Can AI Solve the Persistent AF Paradigm?," will be held Saturday, April 30 from 10:00-11:00 a.m.
