LAVASET is an enhanced Random Forest method that can address correlation in datasets by grouping features based on different correlation metrics and creating fully interpretable latent variables; it reduces noise in feature importance and assigns more accurate importance values

CONFIRMED: Analysis of data obtained over the past 2 weeks by the #DARTMission team shows impact with Dimorphos has successfully altered the asteroid’s orbit by 32 minutes - marking the 1st time humans have changed the orbit of a celestial object in space! go.nasa.gov/3g2C5kp

A black and white image shows a bright object in the upper center of the graphic. This image was taken by the Italian Space Agency's LICIACube and shows white plumes of ejecta streaming from the Dimorphos asteroid after NASA’s Double Asteroid Redirect Test, or DART, mission, made impact with it on Sept. 26, 2022. Rectangles appear to zoom in on the asteroid and represent different levels of contrast. These levels allow scientist's to better see fine structures in the plumes. By studying these streams of material, we will be able to learn more about the asteroid and the impact process.
