Using the photo-sharing site Instagram as a test case, Columbia researchers found that recommendation algorithms influence social status by amplifying network disparities.
Columbia will hold its third annual Data Science Day on March 28. The conference is open to the public and aims to foster collaboration and deepen understanding of issues such as public health and medical research, climate change and financial risk.
The RAD, an audio-based interface that can easily be integrated into existing video games, enables people who are visually impaired to play video games with the same speed and control as sighted players, with full 3D graphics and complex, challenging racetracks.
Columbia engineers are the first to miniaturize dual-frequency combs by putting two frequency comb generators on a single millimeter-sized silicon-based chip — work that could lead to low-cost, real-time portable sensing and spectroscopy in the field.
In this video, Jeannette Wing, Ivan Corwin, John Cunningham, and David Madigan — four of Columbia’s leading investigators — explain their research and Columbia’s commitment to harnessing data science and big data for the benefit of society.
