A new method to boost the speed of online databases
Researchers use machine learning to build faster and more efficient hash functions, which are a key component of databases. Close Hashing is a core operation in most online databases, like a library catalogue or an e-commerce website. A hash function generates codes that replace data inputs. Since these codes are shorter than the actual data, and usually a fixed length, this makes it easier to find and retrieve the original information.

Computer scientists paint a picture of six decades of movies
Researchers say data science may eventually help predict a film's success From the sepia tones of a Coen brothers film set in the Dust Bowl to a child's red coat in Schindler's List, filmmakers have long known the power of colour in movies. Now, computer scientists have analyzed 60 years of films to paint a picture of the past six decades in film.

Phone-based measurements provide fast, accurate information about the health of forests
Researchers have developed an algorithm that uses computer vision techniques to accurately measure trees almost five times faster than traditional, manual methods. Ground-based measurements are hugely valuable, but also time-consuming. We wanted to know whether we could automate this process. Amelia Holcomb The researchers, from the University of Cambridge, developed the algorithm, which gives an accurate measurement of tree diameter, an important measurement used by scientists to monitor forest health and levels of carbon sequestration.
