Walmart employees are out to show its anti-shoplifting AI doesn’t work

  • In an effort to refute the claims made in the Business Insider piece, the Concerned Home Office Associates created a video, which purports to show Everseen’s technology failing to flag items not being scanned in three different Walmart stores.
  • In interviews, the workers, whose jobs include knowledge of Walmart’s loss-prevention programs, said their top concern with Everseen was false positives at self-checkout.
  • One Concerned Home Office Associate said they worry false positives could be causing Walmart workers to break social-distancing guidelines unnecessarily.
  • In an internal communication from April obtained by WIRED, a corporate Walmart manager expressed strong concern that workers were being put at risk by the additional contact necessitated by false positives and asked whether the Everseen system should be turned off to protect customers and workers.

More than a million delivery drones expected in the skies by 2026

  • City leaders have a key role to play in adoption and deployment, Pedro Pacheco, Senior Director Analyst, Gartner, told Cities Today.
  • These uses could demonstrate how drones can enable faster transportation of goods and how, along with other robot deliveries, they could disrupt transport and mobility beyond COVID-19, Pacheco said.
  • A Paris court recently suspended the use of drone surveillance to monitor compliance with COVID-19 measures, citing privacy concerns.
  • The Westport Police Department in Connecticut also dropped plans to pilot drones to enforce social distancing and detect COVID-19 symptoms following concerns from citizens and civil liberties groups.
  • Privacy and no-fly zones “should be captured by cities or governments centrally and enforced onto drone operators,” Pacheco commented.
  • Cities also have a role to play in security and making sure drones and their cargo are not victims of vandalism or theft, and officials will need to consider making space available for drone package pick-up and drop-off points, Pacheco added.

No evidence that mutations to SARS-CoV-2 increase transmissibility

  • An analysis of more than 15,000 SARS-CoV-2 genomes finds that mutations to the virus do not increase its transmissibility and are instead either neutral or detrimental to its spread.
  • There have been concerns that some of these mutations could increase the transmissibility of the virus — that is, its ability to spread between people.
  • Identifying mutations that could increase the virus’s ability to spread throughout the human population is critical, as it could help control the pandemic.
  • Using samples from 15,691 SARS-CoV-2 genomes from COVID-19 patients across the globe, the researchers identified 6,822 different mutations.
  • To determine whether or not the mutations could increase the ability of the virus to spread between people, the researchers modeled the evolutionary tree of SARS-CoV-2.
  • Although this analysis did find 12 independent occurrences of this mutation, the researchers found no evidence to suggest that it is associated with increased transmission.

Researchers say Oura rings can predict COVID-19 symptoms three days early

  • One of the challenges to curbing the spread of COVID-19 is that asymptomatic individuals, or carriers, can spread the virus before they realize they are infected.
  • In April, researchers from West Virginia University’s (WVU) Rockefeller Neuroscience Institute (RNI) and WVU Medicine set out to predict symptoms before they appear using wearable rings by Oura and AI prediction models.
  • Now, the researchers claim their digital platform can detect COVID-19 related symptoms up to three days early with over 90 percent accuracy.
  • The platform is currently being tested by more than 600 healthcare professionals and first responders, and RNI is working with partners like Thomas Jefferson University and Vanderbilt University to scale the test to include more than 10,000 participants.
  • Researchers from the University of California San Francisco (UCSF) are also exploring how Oura Ring might be used to detect the virus in emergency medical workers.

The WIRED Coronavirus Glossary

  • A blood test to reveal Covid-19 antibodies can indicate if a person has had exposure to the virus, or developed a sufficient resistance to it.
  • When the donor is a recovered Covid-19 patient, their plasma may help an infected person fight back the virus and build up immunities to it.
  • Personal Protective Equipment, like masks, gloves, and safety glasses, worn by medical workers and others who may come in direct contact with people infected with the virus.
  • The seclusion of someone who does not exhibit outward symptoms, but may have come into contact with an infected person, until the virus’s incubation period has passed.
  • An order instituted by state and local officials requiring people to stay isolated and inside their homes unless their travel is essential, so as to avoid spreading the virus.

Ross McKitrick: Reopening has risks. So did the Industrial Revolution

  • The real parallel is in reopening the economy — which means facing and managing downside risks while pursuing growth and prosperity.
  • This means we will be building economic activity in an environment with large known benefits but also large potential costs that must be carefully monitored and mitigated.
  • When most economies around the world made the decision to harness fossil fuels they knew about the potential benefits and costs.
  • Thus, facing an opportunity to embark on a path of growth with both enormous potential benefits and considerable downside risks that would need to be carefully monitored and mitigated, every country around the world chose to “open.” They chose to harness the energy, manage and mitigate the downside risks, and enjoy what turned out to be net economic and social benefits beyond the wildest expectations of anyone who had lived in previous generations.

Sweeping Towards Better Coronavirus Forecasting

  • Moreover, with sufficient data augmentation techniques and transfer learning the model should be able to deal with a change in distribution such as the end of social distancing.
  • We aim to incorporate the newest research from deep learning for time series forecasting to address these issues.
  • The most obvious initial challenge with using deep learning revolves around the lack of training data: right now we still only have 110 time steps, at the most, for many US counties.
  • However, despite the widespread success of transfer learning in NLP and computer vision, there is little literature examining its utility for time series forecasting.
  • Next we will consider incorporating demographic data on the number of hospitals in a county, average distance to a hospital, average age, population density, total population, etc., to better forecast admissions and COVID spread.

Trump's Protest Reaction Is Even Worse Than His COVID-19 Response

  • In a press conference this afternoon, Donald Trump took a mandatory few moments to express his condolences to George Floyd.
  • He proceeded to express his genuine remorse over how police have been treated.
  • He then announced that he would be using brute force to end the Black Lives Matter protests.
  • Has anyone informed Trump as to why these protests are happening in the first place?
  • Our most vulnerable communities are protesting because they feel utterly unsafe.
  • He vowed to send extra police, National Guard, and possibly military their way.
  • Not long before Trump had a photo-shoot with a bible, Washington D.C. police shot rubber bullets at the peaceful protestors to clear the way.
  • Now that the president is enforcing strict lockdowns and curfews, do they still feel the same way?
