Naya Rivera — Baby #1 Is a True Outlaw | HollyPost .com

"Glee" star Naya Rivera and husband Ryan Dorsey might be huge Clint Eastwood fans because their first baby has a definite tie to the ole gunslinger. Naya and the "Justified" star just had their first kid -- a boy born on September 17 -- and…

Des diamants gros comme le RitzMenthe fresh

John DerekJohn Derek, lui, coûte que coûte, nous case sa Bo et l’impose au regard des ciné-phages en la présentant sous tous les angles, comme un curieux objet du désir (de son désir sans doute) et dans toutes les postures avec «Elle», «Changements de saisons», «Tarzan l’homme singe» et autres singeries pseudo-érotico-esthétiques. Jean-Luc Godard, lui, nous avait fait le coup de sa Karina l’espace de six films, tous géniaux. Assurément, elle était sa muse au même titre qu’Anne Wiazemski qui lui succéda Même Ingmar Bergman sacrifia au – rite cinématographique du couple fétiche, et encore tant d’autres. Le plus joli reste peut-être celui que forma Ingrid Bergman avec Roberto Rossellini. Orson Welles et Rita Hayworth n’étaient pas mal non plus dans le one-shot meurtrier de «La dame de Shanghai»! Revenons à la Bergman qui quitta Hollywood et ses sunlights qui lui brulaient les ailes pour l’Italie, Rossellini et l’amour… Roma-amor ! Cette échappée belle donna naissance à plein d’enfants et quelques films : «Stromboli», «Europa 51», «Voyage en Italie». On ne pardonna jamais vraiment à Ingrid Bergman d’avoir ainsi trahi Hollywood pour se donner à un homme, sa vie, son œuvre… Restent les films, une œuvre sublime qu’Hollywood n’aurait jamais pu financer, même avec des dollars à la tonne ! Quant au couple Clint East-wood/Sondra Locke, si leur liaison cinématographique et amoureuse dure depuis longtemps, il a su se protéger des «bloody sunlights» d’Hollywood. Sondra Locke passe même pour une marginale, elle qui vient de réaliser son premier film, «Ratboy», un conte truffé d’allusions à la célébrité et son infortune. La frêle Sondra et son divin Clint se sont immortalisés dès 1976 à travers «Josey Wales hors-la-loi», puis «L’épreuve de force», «Dirty Harry/Sudden impact» et «Bronco Billy»… des films réalisés par Clint Eastwood lui-même. Carlos Saura, lui, a eu ses années Geraldine Chaplin avec «La madriguera», «Maman a cent ans», «Ana et les loups», «Cria cuer-vos», «Les yeux bandés». Exit Geraldine et les règlements de compte avec l’époque franquiste. Avec Laura, Del Sol, Saura trouve une autre source d’inspiration, nettement plus orientée vers la musique, la danse. Avec la complicité des yeux de Laura, c’est «Carmen» puis «L’amour sorcier».

SAT - Neuroscience News

The Allen Institute for Artificial Intelligence (AI2) and University of Washington researchers have created an artificial intelligence (AI) system that can solve SAT geometry questions as well as the average American 11th-grade student, a breakthrough in AI research.

This system, called GeoS, uses a combination of computer vision to interpret diagrams, natural language processing to read and understand text and a geometric solver to achieve 49 percent accuracy on official SAT test questions. If these results were extrapolated to the entire Math SAT test, the computer roughly achieved an SAT score of 500 (out of 800), the average test score for 2015.

A paper outlining the research, “Solving Geometry Problems: Combining Text and Diagram Interpretation,” was a joint effort between the UW Computer Science & Engineering department and AI2.

These results, presented at the 2015 Conference on Empirical Methods in Natural Language Processing (EMNLP) in Lisbon, Portugal, were achieved by GeoS solving unaltered SAT questions that it had never seen before and that required an understanding of:

* Implicit relationships

* Ambiguous references

* The relationships between diagrams and natural-language text

“Unlike the Turing Test, standardized tests such as the SAT provide us today with a way to measure a machine’s ability to reason and to compare its abilities with that of a human,” said Oren Etzioni, CEO of AI2. “Much of what we understand from text and graphics is not explicitly stated, and requires far more knowledge than we appreciate. Creating a system to be able to successfully take these tests is challenging, and we are proud to achieve these unprecedented results.”

Said Ali Farhadi, senior research manager for Vision at AI2 and UW assistant professor of computer science and engineering, “We are excited about GeoS’s performance on real-world tasks. Our biggest challenge was converting the question to a computer-understandable language. One needs to go beyond standard pattern-matching approaches for problems like solving geometry questions that require in-depth understanding of text, diagram and reasoning.”

How GeoS Works

GeoS is the first end-to-end system that solves SAT plane geometry problems. It does this by first interpreting a geometry question by using the diagram and text in concert to generate the best possible logical expressions of the problem, which it sends to a geometric solver to solve. Then it compares that answer to the multiple-choice answers for that question.

A demonstration of the system’s problem-solving is available here.

This process is complicated by the fact that SAT questions contain many unstated assumptions.

For example, in the SAT problem at right, there are several unstated assumptions, such as the fact that lines BD and AC intersect at E, that “circle O has a radius of 5” is the same as “circle O radius equals 5” and that the drawing may or may not be to scale.

GeoS had a 96 percent accuracy rate on questions it was confident enough to answer, which is an important dimension of learning. Today, GeoS can solve plane geometry questions; AI2 is moving to solve the full set of SAT math questions in the next three years.

As part of AI2’s commitment to sharing its research for the common good, all data sets and software are available for other researchers to use.

AI2 is also building systems that can tackle science tests, which require a knowledge base that includes elements of the unstated, common-sense knowledge that humans generate over their lives. This Aristo project is described here.
