New dinosaur discovered in Sahara desert was a horned 'hell heron'

Popular Science

New dinosaur discovered in Sahara desert was a horned'hell heron' 'Spinosaurus mirabilis' sported a 20-inch-tall'scimitar' on its head. Spinosaurus mirabilis stands along river's edge over its prey some 95 million years ago. A scimitar-shaped head crest and interdigitating teeth characterize this wading giant, one of the last-surviving spinosaurid species. Breakthroughs, discoveries, and DIY tips sent six days a week. Paleontologists still know comparatively little about fin-backed dinosaurs .


Optimal Subsampling with Influence Functions

Neural Information Processing Systems

As the amount of data increases, the question arises as to how best to deal with the large datasets. While computational platforms such as Spark [28] and Ray [23] help process large datasets once a desired model is chosen, simply using smaller data can be a faster solution for exploratory data modeling, rapid prototyping, or other tasks where the accuracy obtainable from the full dataset is notneeded.
