Can Chen and two of his former doctoral students, Shiyang Xiao at Syracuse University and Boyuan Zhao at Florida International University,…

Credit: Pixabay/CC0 Public Domain Issues such as abrupt changes in speed limits and incomplete lane markings are among the most influential factors that can predict road crashes, finds new research by University of Massachusetts Amherst engineers. The study then used machine learning to predict which roads may be the most dangerous based on these features.…

The experiment can be divided into two stages, as seen in this schematic. In stage 1, the subject takes an interview conversation experiment and the procedure is recorded by the camera for further analysis. In stage 2, the subject completes a questionnaire related to supervisor-student effect evaluation. The questionnaire data are added to construct a structural equation model for study 2 analysis.

Computer scientists at MIT joined forces with oceanographers to develop a machine-learning model that incorporates knowledge from fluid dynamics to generate more accurate predictions about the velocities of ocean currents. This figure shows drifting buoy trajectories in the Gulf of Mexico superimposed on surface currents. The red dots mark the buoys’ positions on March 9, 2016, and the tails are 14 days long.

Researchers develop tools to help data scientists make the features used in machine-learning models more understandable for end users. Explanation methods that help users understand and trust machine-learning models often describe how much certain features used in the model contribute to its prediction.

An overview and story of various different preprocessing techniques, as well as where they apply in machine-learning(image by padrefilar on pixabay)A very common misconception that new and aspiring Data Scientists often have when entering the domain is that most of Data Science revolves around artificial intelligence, machine-learning, and other popular and obscure buzzwords. While many of these buzzwords are certainly different aspects of Data Science, and we really do program machine-learning models, the majority of the…

A predictive map of Cook County in 2030, far right, shows how the racial composition of neighborhoods will change compared to maps using U.S. Census data from 2010 and 2020. Credit: Tomasz Stepinski/UC A map created by researchers at the University of Cincinnati can predict with surprising accuracy how the racial makeup of neighborhoods will change.…

MIT researchers find that the explanation methods designed to help users determine whether to trust a machine-learning model’s predictions can perpetuate biases and lead to worse outcomes for people from disadvantaged groups.
