Prediction of repurposed drugs for Coronaviruses using artificial intelligence and machine learning - PubMed

#artificialintelligence

The world is facing the COVID-19 pandemic caused by Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2). Likewise, other viruses of the Coronaviridae family were responsible for causing epidemics earlier. To tackle these viruses, there is a lack of approved antiviral drugs. Therefore, we have developed robust computational methods to predict the repurposed drugs using machine learning techniques namely Support Vector Machine, Random Forest, k-Nearest Neighbour, Artificial Neural Network, and Deep Learning. We used the experimentally validated drugs/chemicals with anticorona activity (IC50/EC50) from'DrugRepV' repository.


Can we be friends? Dating apps say sex isn't everything in a post-pandemic world

The Japan Times

I've just come out of a long-term lockdown. Instead, they crave the friendships and social groups they have been starved of over the past year. That's the verdict of dating apps such as Tinder and Bumble, which are launching or acquiring new services focused entirely on making and maintaining friends. "There's a really interesting trend that has been taking place in the connection space, which is this desire to have platonic relationships," said Bumble founder and CEO Whitney Wolfe Herd. "People are seeking friendship in ways they would have only done offline before the pandemic."


6 Steps Companies Can Take to Strengthen Their Cyber Strategy - InformationWeek

While these technical skills are certainly important, we're also now looking more holistically at candidates to test their abilities to think critically and creatively as well as uncover new solutions. As we face new and unprecedented challenges in cyber protection, it's critical that cyber leaders hire team members who think outside-the-box, have intellectual curiosity, employ bold thinking, and are natural problem solvers. Protecting an organization against advanced cyber threats requires innovative thinking and techniques; people, process and technology capabilities are needed to properly defend ourselves against sophisticated attackers, such as nation states. Cyber threats will continue to evolve, as will the new techniques described above to enable cyber resiliency. Ariel Weintraub is currently the Head of Enterprise Cyber Security at MassMutual.

Machine learning enhances non-verbal communication in online classrooms

#artificialintelligence

June 21, 2021--Researchers in the Center for Research on Entertainment and Learning (CREL) at the University of California San Diego have developed a system to analyze and track eye movements to enhance teaching in tomorrow's virtual classrooms – and perhaps future virtual concert halls. UC San Diego music and computer science professor Shlomo Dubnov, an expert in computer music who directs the Qualcomm Institute-based CREL, began developing the new tool to deal with a downside of teaching music over Zoom during the COVID-19 pandemic. "In a music classroom, non-verbal communication such as facial affect and body gestures is critical to keep students on task, coordinate musical flow and communicate improvisational ideas," said Dubnov. "Unfortunately, this non-verbal aspect of teaching and learning is dramatically hampered in the virtual classroom where you don't inhabit the same physical space." To overcome the problem, Dubnov and Ph.D. student Ross Greer recently published a conference paper on a system that uses eye tracking and machine learning to allow an educator to make'eye contact' with individual students or performers in disparate locations – and lets each student know when he or she is the focus of the teacher's attention.


As U.S. Cruises Resume, Operators Outfit Ships With Contact-Tracing Tech

WSJ.com: WSJD - Technology

"All of that technology helps health and safety as we return to service," said Jay Schneider, a Royal Caribbean Group senior vice president and its chief product innovation officer. The Morning Download delivers daily insights and news on business technology from the CIO Journal team. Large cruise ships, capable of hosting 5,000 passengers or more, proved a ready setting for the spread of Covid-19 during the early days of the pandemic. Now, cruises will have the advantage of catering to a population with access to the vaccine, though there is no guarantee every passenger will be vaccinated. Royal Caribbean, which owns and operates the Royal Caribbean International, Celebrity Cruises and Silversea Cruises brands, recently developed a wrist device, the "Tracelet," to help with contact-tracing.


The CDC launches a Spanish language WhatsApp chatbot to help people find vaccines

Engadget

The CDC and WhatsApp have teamed up on a Spanish language vaccine-finder service to help reach people who have yet to get COVID-19 vaccines. The service, called "Mi chat sobre vacunas COVID," is a chatbot that helps users find locations to get vaccinated, and find free rides to get there. Importantly, the service will also counter common misinformation about the shots, with details on side effects and why it's important to get vaccinated. That extra info is important as Latino communities in particular have been targeted by a wave of vaccine misinformation throughout the pandemic -- much of it spread via WhatsApp -- that officials say has fueled vaccine hesitancy. The chatbot is available by messaging "hola" to 1-833-636-1122 or can be accessed directly here.


Responsible Computing During COVID-19 and Beyond

Communications of the ACM

The COVID-19 pandemic has both created and exacerbated a series of cascading and interrelated crises whose impacts continue to reverberate. From the immediate effects on people's health to the pressures on healthcare systems and mass unemployment, millions of people are suffering. For many of us who work in the digital technology industry, our first impulse may be to devise technological solutions to what we perceive as the most urgent problems when faced by crises such as these. Although the desire to put our expertise to good use is laudable, technological solutions that fail to consider broader social, political, and economic contexts can have unintended consequences, undermining their efficacy and even harming the very communities that they are intended to help.10 To ensure our contributions achieve their intended results without causing inadvertent harm, we must think carefully about which projects we work on, how we should go about working on them, and with whom such work should be done.


An Enlightened Future with Artificial Intelligence

#artificialintelligence

The decisions that we make now and in the near future will set the tone for the rest of the decade including how artificial intelligence (AI) may develop and how we will use it. It will require enlightened leadership to maximise the benefit for human society. This article is focused on providing a moment of reflection in terms of where we are and where we are going from a policy and philosophical perspective and to serve as a prelude to a more technical article on the next generation of AI that will follow. Positive use case potential for AI includes the fight against Covid -19. For example The Lancet published an article authored by Zhou et al. entitled "Artificial Intelligence in COVID-19 drug repurposing" and state that " In this Review, we introduce guidelines on how to use AI for accelerating drug repurposing or repositioning, for which AI approaches are not just formidable but are also necessary. We discuss how to use AI models in precision medicine, and as an example, how AI models can accelerate COVID-19 drug repurposing."


Customer Insights 2021 Predictions: Evolution And Collaboration

#artificialintelligence

CI leaders will shift 10% of their budgets to emotion analytics. Emotions are a more important driver of consumer decisions than rational thought and thus are the largest factor in brand energy, customer experience, and marketing effectiveness. But for the past decade, CI professionals have leaned into the precision of big data analytics instead of the traditionally unquantifiable territory of emotion. New techniques change this dynamic: AI-based text analytics tools such as Clarabridge and IBM Watson improve the precision of cruder sentiment analysis tools, while firms such as Nielsen and Realeyes bring biometric and facial analysis methodologies from the lab to the business world. As data analytics becomes commoditized, firms will shift 10% of the insights budget to emotion analytics to pilot new techniques in search of competitive advantage in the "why" behind consumer behavior, not just the "what" that data analytics addresses. Companies will reorganize to ensure CX and CI collaboration.


I'm Scared of the Person TikTok Thinks I Am

The Atlantic - Technology

Something is wrong with me, and TikTok knows it. I can tell because its recommendation algorithm keeps providing me with videos that only a horrible person would like. One morning last week, the app recommended a video of a girl in a red dress saying slowly, "I'm officially at the age where I can date you … or your dad." In the next video, a "doctor" tried to sell me some kind of coffee-based weight-loss drink. An "age reveal" came after, from a woman who looked like she was in her 20s but was actually 43.
