  • The machine-learning algorithm works by analyzing the online behavior of visitors to the Northwell Health website and comparing that data to future COVID-19 hospitalizations.
  • The tool, which uses anonymized data, has so far predicted hospitalizations with an accuracy rate of 80 percent.
  • Machine-learning tools are helping health-care professionals worldwide better constrain and treat COVID-19.

    Catching serial killers with an algorithm

    This week, Big Think is partnering with Freethink to bring you amazing stories of the people and technologies that are shaping our future.

    • There are over 250,000 unsolved murder cases in the United States. Thomas Hargrove, cofounder of Murder Accountability Project, wants that number to be as close to zero as possible, and he has just the tool to help.
    • Hargrove developed an algorithm that, through cluster analysis, is capable of finding connections in murder data that human investigators tend to miss.
    • The technology exists, but a considerable roadblock that the project faces is getting support and cooperation from law enforcement offices.
