You Are What You Talk About: Inducing Evaluative Topics for Personality Analysis
Jukić, Josip, Vukojević, Iva, Šnajder, Jan
Expressing attitude or stance toward entities and concepts is an integral part of human behavior and personality. Recently, evaluative language data has become more accessible with social media's rapid growth, enabling large-scale opinion analysis. However, surprisingly little research examines the relationship between personality and evaluative language. To bridge this gap, we introduce the notion of evaluative topics, obtained by applying topic models to pre-filtered evaluative text from social media. We then link evaluative topics to individual text authors to build their evaluative profiles. We apply evaluative profiling to Reddit comments labeled with personality scores and conduct an exploratory study on the relationship between evaluative topics and Big Five personality facets, aiming for a more interpretable, facet-level analysis. Finally, we validate our approach by observing correlations consistent with prior research in personality psychology.
Six with ties to MIT honored as 2022 ACM Fellows
On Jan. 18, the Association for Computing Machinery (ACM) announced its 2022 fellows, those it recognizes "for significant contributions in areas including cybersecurity, human-computer interaction, mobile computing, and recommender systems among many other areas." Included in the crop of new fellows were six distinguished scientists with ties to MIT. Constantinos Daskalakis, the Armen Avanessians (1982) Professor in the Department of Electrical Engineering and Computer Science (EECS), was honored "for contributions to the foundations of algorithmic game theory, mechanism design, sublinear algorithms, and theoretical machine learning." Daskalakis is a theoretical computer scientist who works at the interface of game theory, economics, probability theory, statistics, and machine learning. His current work focuses on multi-agent learning, learning from biased and dependent data, causal inference and econometrics.
Council Post: How An Automation CMO Views ChatGPT
Robocorp CMO Dave Dabbah is a full-stack marketing leader with a proven record of success driving growth and brand recognition. The ChatGPT revolution has officially gone into full unicorn mode, which theoretically should mean that marketers across the globe can now significantly increase their ability to produce high-quality content at scale. I'll let the cat out of the bag early in this article to say that I believe the underlying technology that makes ChatGPT so good will revolutionize how marketing teams produce content in the future. Although "revolutionize" is an overused term, the potentially far-reaching effects of an AI-powered service delivering high-quality content are among the most exciting developments in the tech industry that I have seen, reminiscent of the game-changing impact of Napster (in which I may have downloaded the entire Nirvana collection in under 60 seconds). I believe that the introduction of ChatGPT, which utilizes AI to deliver information, will be as impactful on content producers as the birth of the internet.

An investigation of challenges encountered when specifying training data and runtime monitors for safety critical ML applications
Heyn, Hans-Martin, Knauss, Eric, Malleswaran, Iswarya, Dinakaran, Shruthi
Context and motivation: The development and operation of critical software that contains machine learning (ML) models requires diligence and established processes. Especially the training data used during the development of ML models have major influences on the later behaviour of the system. Runtime monitors are used to provide guarantees for that behaviour. Question / problem: We see major uncertainty in how to specify training data and runtime monitoring for critical ML models and by this specifying the final functionality of the system. In this interview-based study we investigate the underlying challenges for these difficulties. Principal ideas/results: Based on ten interviews with practitioners who develop ML models for critical applications in the automotive and telecommunication sector, we identified 17 underlying challenges in 6 challenge groups that relate to the challenge of specifying training data and runtime monitoring. Contribution: The article provides a list of the identified underlying challenges related to the difficulties practitioners experience when specifying training data and runtime monitoring for ML models. Furthermore, interconnection between the challenges were found and based on these connections recommendation proposed to overcome the root causes for the challenges.
B2B Marketing and AI for Streamlined and Strategic Communications: Peter Prodromou on Marketing Smarts [Podcast]
What can marketers bring to the mix when AI is so powerful? Don't miss a MarketingProfs podcast, subscribe to our free newsletter! Passion, for one thing, says Peter Prodromou of Boathouse. "If you're in the upper right-hand corner with passion, chances are people are going to want to work with you or buy your product," he says on the latest episode of Marketing Smarts. "Think about Apple and Tesla; those are two brands that are very much about passion. Your ability to convey that is critically important." AI is just an algorithm, after all. "Everybody is going to shop at Amazon because they have the best algorithm, and there may or may not be passion for it," Peter says.
Artificial intelligence predicts climate change coming faster than we recently thought, new study says
The world faces a significant risk of passing a crucial global warming threshold earlier than scientists had suggested, possibly as soon as 2050, a paper published Monday found. The threshold is the point at which Earth's overall temperature has increased by 2.0 degrees Celsius, or 3.6 degrees Fahrenheit. If greenhouse gas emissions remain at high levels, there's a 50% probability the world could reach that catastrophic milestone before 2050, said co-author Noah Diffenbaugh, a climate scientist at Stanford University. The chance it could reach 2.0 degrees before 2058 is 84 in 100. Earlier estimates had put it closer to the end of the century.
Artificial intelligence used to predict space weather - SpaceRef
A Northumbria University physicist has been awarded more than half a million pounds to develop artificial intelligence which will protect the Earth from devastating space storms. Activity from the Sun such as solar eruptions, known as Coronal Mass Ejections, results in plasma being fired towards Earth at supersonic speeds, which can result in serious disruption to power and communication systems. With our increasing reliance on technology, solar storms pose a serious threat to our everyday lives, leading to severe space weather being added to the UK National Risk Assessment for the first time in 2011. Northumbria's Dr Andy Smith has recently been awarded a Research Fellowship from the Natural Environment Research Council (NERC) to explore how physics-inspired machine learning could be used to forecast space weather more accurately and predict serious space storms. During the Next Generation, Physics-Inspired AI for Space Weather Forecasting project, Dr Smith and his team will analyse huge amounts of data from satellites and space missions over the last 20 years to gain a better understanding of the conditions under which storms are likely to occur.
