Phys.Org Mobile: New algorithm can separate unstructured text into topics with high accuracy and reproducibility

Phys.Org Mobile: New algorithm can separate unstructured text into topics with high accuracy and reproducibility | Science, Technology, and Current Futurism | Scoop.it
"To create a better algorithm, Amaral took a network approach. The result, called TopicMapping, begins by preprocessing data to replace words with their stem (so "star" and "stars" would be considered the same word). It then builds a network of connecting words and identifies a "community" of related words (just as one could look for communities of people in Facebook). The words within a given community define a topic. "The algorithm was able to perfectly separate the documents according to language and was able to reproduce its results. It also had high accuracy and reproducibility when separating 23,000 scientific papers and 1.2 million Wikipedia articles by topic."

Nine Scientific Pioneers Receive the 2014 Kavli Prizes | The Kavli Foundation

Nine Scientific Pioneers Receive the 2014 Kavli Prizes | The Kavli Foundation | Science, Technology, and Current Futurism | Scoop.it

Nine pioneering scientists have been named this year’s recipients of the Kavli Prizes – prizes that recognize scientists for their seminal advances in astrophysics, nanoscience and neuroscience. This year’s laureates were selected for pioneering the theory of cosmic inflation, for transformative contributions to the field of nano-optics and for the discovery of specialized brain networks for memory and cognition.

 
Sharrock's insight:

My main interest is in the neuroscience fields: "The Kavli Prize in Neuroscience is shared between Brenda Milner, Montreal Neurological Institute, McGill University, Canada, John O’Keefe, University College London, UK, andMarcus E. Raichle, Washington University in St.Louis School of Medicine, USA. They receive the prize “for the discovery of specialized brain networks for memory and cognition”.

The recipients of the Kavli Prize in Neuroscience have all played major roles in advancing our understanding of memory and in the development of techniques to measure the brain. They have discovered that these functions are produced by specialized systems in the brain, which they analysed through a variety of research approaches. They have found the specific regions of the brain that are involved in memory, and how specialized nerve cells perform different roles.

The higher cognitive functions of our brains such as attention, memory, and planning are crucial to create our rich mental lives: memory is essential for humans, from the recognition of where we are, through learning new skills, to being able to recall events. In humans memory can be said to define who we are, and we know that loss of memory can have devastating effects on an individual’s personality. Knowing how memory function should work in healthy people could open the door to understanding what has changed in patients with dementia and memory loss."

Boris "sees" objects with depth sensors on its face and wrists. In 10 seconds it calculates up to a thousand possible ways to grasp a novel object with its five robotic fingers and plans a path of arm movements to reach its target, avoiding obstructions.

"It's not been programmed to pick it up - it's been programmed to learn how to pick it up," explained Professor Wyatt.

The school standards rebellion

The school standards rebellion | Science, Technology, and Current Futurism | Scoop.it
Florida students no longer need chemistry, physics or Algebra II to graduate from high school. Texas just scrapped its Algebra II requirement. And the Washington state board of education last month reversed its own resolution calling for a foreign language mandate, over concerns that it appeared too elitist. A standards rebellion — or in the...
Sharrock's insight:

Push-back leading to reduced standards. The rationale for educating students with skills that will get them jobs *NOW* may seem rational and effective *NOW*, but that's not what planning or preparation is. I agree with the statement that vocational skills are valuable, but also agree that students should also be challenged to reach standards of other students. My conderns mirror those indicated in this statement: "Especially worrisome: The risk that low-income and minority students, as well as children with disabilities, could be pushed into the vocational tracks."
