Deep learning neural networks can be massive, demanding major computing power. In a test of the "lottery ticket hypothesis," MIT researchers have found leaner, more efficient subnetworks hidden within BERT models. The discovery could make natural language processing more accessible.
A groundbreaking study published in Information & Communications Technology Law by experts at the Centre for Law and Development at Qatar University discusses the legal and ethical implications of Big Tech's development of "digital thought clones." Digital thought clones can allow technology companies to accurately predict and influence people's behavior according to their digital habits. The authors call for legislation to protect people from technology companies' malicious use of their digital footprint.
General smartphone usage is a poor predictor of anxiety, depression or stress say researchers, who advise caution when it comes to digital detoxes. Researchers measured the time spent on smartphones by 199 iPhone users and 46 Android users for one week. Surprisingly, the amount of time spent on the smartphone was not related to poor mental health. Instead, the study found that mental health was associated with concerns and worries about their own smartphone usage.
Researchers from the Leibniz Institute of Photonic Technology, Jena University and University Hospital have developed an optical toolbox to build microscopes for a few hundred euros that deliver high-resolution images comparable to commercial microscopes that cost up to a thousand times more. The 3D printed open-source modular system can be combined in the way the research question requires -- from the observation of living organisms in the incubator to a toolbox for education.
Why do so many Republicans still believe that the recent US presidential election was fraudulent? Is it possible to reach coronavirus deniers with factual arguments? A study by researchers at the Max Planck Institute for Human Development and the University of Amsterdam provides insights into what it is that stops people from changing their minds. Their findings have been published in the journal Proceedings of the Royal Society of London B.
The rise of online hate speech is a disturbing, growing trend in countries around the world, with serious psychological consequences and the potential to impact, and even contribute to, real-world violence. A new paper offers a framework for studying the dynamics of online hate and counter speech, and offers the first large-scale classification of millions of instances such interactions on Twitter.
Scientists at the Complexity Science Hub Vienna show that the accelerating fragmentation of society - often referred to as filter bubbles -- is a direct consequence of the growing number of social contacts. According to their new theory of social fragmentation, societies can only be either cohesive or fragmented, with abrupt changes from one state to the other at certain tipping points. Filter bubble societies are a risk for democracies.
In a pair of studies, Hong Tien Vu of the University of Kansas found that the way media organizations and global climate change NGOs frame their messages on the topic does in fact influence how people look at the issue, which in turn affects what action, if any, is taken to fight the problem.
MCUNet is a new MIT system that brings machine learning to microcontrollers. The advance could enhance the function and security of devices connected to the Internet of Things (IoT).
Delivering ECR ads too early can engender worse purchase rates than without delivering them, thus wasting online advertising budgets.
