Yen and dollar highs offer macro hedge funds some relief - Artificial Intelligence Online

#artificialintelligence

June was kind to macro hedge funds. They were up more than 3 per cent, in what was their best month since 2010, according to data from Hedge Fund Research, buoyed by long positions on the yen and -- for the most fortunate -- long on both the yen and the dollar, and short sterling. Currencies and currency-related trades have been among the few bright spots for hedge funds recently (along with gold, which has risen more than 30 per cent since the end of 2015, according to Credit Suisse). Riding the yen and dollar up and taking on derivative trades, such as shorting Chinese companies that have lots of US dollar debt and dollar costs, have been among the few clear trends to follow. But generally, these are challenging times for the industry both in the short and longer term.


Retrospective Causal Inference with Machine Learning Ensembles: An Application to Anti-Recidivism Policies in Colombia

arXiv.org Machine Learning

We present new methods to estimate causal effects retrospectively from micro data with the assistance of a machine learning ensemble. This approach overcomes two important limitations in conventional methods like regression modeling or matching: (i) ambiguity about the pertinent retrospective counterfactuals and (ii) potential misspecification, overfitting, and otherwise bias-prone or inefficient use of a large identifying covariate set in the estimation of causal effects. Our method targets the analysis toward a well defined ``retrospective intervention effect'' (RIE) based on hypothetical population interventions and applies a machine learning ensemble that allows data to guide us, in a controlled fashion, on how to use a large identifying covariate set. We illustrate with an analysis of policy options for reducing ex-combatant recidivism in Colombia.


US Artificial Intelligence Market to Grow at a Staggering 75% CAGR Until 2021: TechSci Research /PR Newswire UK/

#artificialintelligence

According to TechSci Research report, "United States Artificial Intelligence Market, By Application, By Region, By End User Competition Forecast & Opportunities, 2011-2021", the artificial intelligence market in the US is projected to grow at a CAGR of 75% during 2016 - 2021 on account of growing artificial intelligence technology adoption in consumer electronic devices, research and developmental activities in healthcare industry, unmanned aerial vehicles, autonomous cars, etc. Moreover, venture capital investments in this sector, are in full swing, especially in the US. The country is witnessing numerous start-ups sprouting every year, backed by various angel investors and venture capitalists. Major venture capitalist active in the United States artificial intelligence market include Accel, General Catalyst Partners, GV, Work-Bench, Promus Ventures, Kleiner Perkins Caulfield & Byers, Khosla Ventures, Samsung Electronics, Wipro Technologies, Samsung Global Innovation Centre, Goldman Sachs, Bank of America Merrill Lynch, and Formation 8, among others. In 2015, western region of the United States dominated the artificial intelligence market of the country, on account of presence of major end users such as cyber security solution providers, healthcare institutes, government headquarters, etc., in the region.


What it actually takes for schools to 'go digital' - The Hechinger Report

#artificialintelligence

Soon, the glow of hundreds of screens illuminates each face in every classroom. Inside Skye Templeton's seventh-grade Social Studies class, students are enthralled by online documents and videos about the casualties of World War II. Nearby, in Sara Sharpe's sixth-grade math class, a small group of students works through computer drills covering ratios and percents. And, across the hallway, English and Language Arts teacher Lori Meyer expresses amazement at how much her eighth graders enjoyed doing their final project: a research paper and iMovie on the 1960s. With their MacBooks, students researched topics, wrote their papers, and submitted to their teacher via email. "This is the first time in my 12 years of teaching that students said writing the research paper was their favorite assignment," Meyer said, "and I know it was due to the laptops."


Robot-delivered lethal explosive in Dallas police standoff was a first, experts say

PBS NewsHour

Members of the Boston Police bomb squad demonstrate a robot named "Slick" during an active shooter drill at Fenway Park in Boston, Massachusetts, U.S. June 12, 2016. Experts say Dallas police executed an unprecedented move Friday morning, when officers used a robot-delivered bomb to engage a suspect accused of fatally shooting five police officers and injuring seven others during a protest. The shooting started toward the end of a non-violent protest over recent fatal police shootings. Police engaged in a standoff with the suspect, who was later identified as Micah Xavier Johnson, after he barricaded himself inside a parking garage. Following lengthy negotiations with the police, Johnson told officers he had planted bombs in the area.


Beating level-set methods for 3D seismic data interpolation: a primal-dual alternating approach

arXiv.org Machine Learning

Acquisition cost is a crucial bottleneck for seismic workflows, and low-rank formulations for data interpolation allow practitioners to `fill in' data volumes from critically subsampled data acquired in the field. Tremendous size of seismic data volumes required for seismic processing remains a major challenge for these techniques. We propose a new approach to solve residual constrained formulations for interpolation. We represent the data volume using matrix factors, and build a block-coordinate algorithm with constrained convex subproblems that are solved with a primal-dual splitting scheme. The new approach is competitive with state of the art level-set algorithms that interchange the role of objectives with constraints. We use the new algorithm to successfully interpolate a large scale 5D seismic data volume, generated from the geologically complex synthetic 3D Compass velocity model, where 80% of the data has been removed.


5 bots that could change democracy

#artificialintelligence

You may have heard about the Donald Trump bot army and the Twitter bots that have influenced elections in Latin America, but there are other bots out there, bots that connect citizens to services, bots that plan to crowdsource the election of a president or act as your personal assistant in government. They're going to change civil society, how people interact with government, and the self-governance of free societies. Here are five example of bots that have already impacted or will impact democracy. Dirty Water VT sends a tweet each time a sewage spill occurs in the state of Vermont. Trib IL CampaignCash sends a tweet any time a campaign contribution is made above 1,000 in the state of Illinois.


SendPulse - Product Hunt

Therefore, SendPulse will add Italian, French, German, Turkish, Simple Chinese, Indonesian, Korean, Japanese, Arabic, and by the way, Spanish (LatAmerica), Brazilian Portuguese localization. Currently we've used pre-launch product for English and Russian audience. In total we will be have 13 foreign language groups. The language detection are based on geolocation. The modeling technology is based on math method, behavioral analyses to find lookalike audiences (digital twins) to create on behavior models in consuming content, clicks, design, social demographics - the simple comparison will be Facebook Artificial Intelligence for native advertising.


The AI Law Firm - Turing & Partners

#artificialintelligence

'We have arrived,' the personal assistant announced as the automated share car pulled up outside Turing & Partners, one of London's best-known AI-powered law firms. Elon Turing looked up from his notes that were projected before him and got out at the curb on Gresham Street, not far from the Bank of England. It was very warm, as it always was these days, though there was a heaviness in the air that promised a thunder storm. Elon nodded to the car, which zipped away into the pollution free morning and disappeared into a sea of auto-taxis, self-driving buses and other share cars. He took a deep breath and marched up to the front door of the building. The door scanned his face and opened, greeting him politely as he walked into the cooled lobby. At the reception desk was Albert.
