This Indian-origin scientist has discovered a new way to filter fake news; read details IANS New York: Using machine learning (ML), a team of US researchers led by Indian-American computer scientist Anshumali Shrivastava at Rice University has discovered an efficient way for social media companies to keep misinformation from spreading online. Their method applies machine learning in a smarter way to improve the performance of Bloom filters, a widely used technique devised a half-century ago. Using test databases of fake news stories and computer viruses, Shrivastava and statistics graduate student Zhenwei Dai showed their Adaptive Learned Bloom Filter (Ada-BF) required 50 per cent less memory to achieve the same level of performance as learned Bloom filters.
