False Discovery Rate Control and Statistical Quality Assessment of Annotators in Crowdsourced Ranking
Xu, Qianqian, Xiong, Jiechao, Cao, Xiaochun, Yao, Yuan
With the rapid growth of crowdsourcing platforms it has become easy and relatively inexpensive to collect a dataset labeled by multiple annotators in a short time. However due to the lack of control over the quality of the annotators, some abnormal annotators may be affected by position bias which can potentially degrade the quality of the final consensus labels. In this paper we introduce a statistical framework to model and detect annotator's position bias in order to control the false discovery rate (FDR) without a prior knowledge on the amount of biased annotators - the expected fraction of false discoveries among all discoveries being not too high, in order to assure that most of the discoveries are indeed true and replicable. The key technical development relies on some new knockoff filters adapted to our problem and new algorithms based on the Inverse Scale Space dynamics whose discretization is potentially suitable for large scale crowdsourcing data analysis. Our studies are supported by experiments with both simulated examples and real-world data. The proposed framework provides us a useful tool for quantitatively studying annotator's abnormal behavior in crowdsourcing data arising from machine learning, sociology, computer vision, multimedia, etc.
LSTM Neural Reordering Feature for Statistical Machine Translation
Cui, Yiming, Wang, Shijin, Li, Jianfeng
Artificial neural networks are powerful models, which have been widely applied into many aspects of machine translation, such as language modeling and translation modeling. Though notable improvements have been made in these areas, the reordering problem still remains a challenge in statistical machine translations. In this paper, we present a novel neural reordering model that directly models word pairs and their alignment. Further by utilizing LSTM recurrent neural networks, much longer context could be learned for reordering prediction. Experimental results on NIST OpenMT12 Arabic-English and Chinese-English 1000-best rescoring task show that our LSTM neural reordering feature is robust, and achieves significant improvements over various baseline systems. 1 Introduction In statistical machine translation, the language model, translation model, and reordering model are the three most important components.
Microsoft features machine-learning startups at pitch night
One startup makes a website that connects high-school students with the ideal college. Another operates a chatbot that can answer your simple medical questions. All have the resources of Microsoft backing them. Nine companies made pitches onstage Thursday night at Showbox SoDo as part of Microsoft Accelerator's third demo day in Seattle. The program selects 10 to 15 companies twice a year to participate in a startup accelerator program that provides resources, Microsoft Azure credits, and -- perhaps most compelling -- introductions to Microsoft's deep pool of customers.
Deep learning: How the mining industry got smart
Recovering the planet's natural resources is hard. It's difficult, dangerous, and can be environmentally damaging. Cue an IT revolution, with smart communications, 'extreme Wi-Fi' covering vast deserts, autonomous vehicles that extract vital rocks and minerals, and geofenced employees who receive warnings if they get close to a mine's famously colossal big machinery. There's even a'smart bolt' that creates an underground support structure which is classic Internet of Things. The final goal is the autonomous mine, where humans are completely removed from the mining process.
We now have the tech to fingerprint babies โ but should we?
That's the age of one participant in a recent study looking at ways to take the fingerprints of infants. "The pattern is there at birth," says Anil Jain at Michigan State University in East Lansing. But it is hard to capture. Now Jain and his colleagues are developing a device that could be up to the task. Taking fingerprints from very young children โ even newborns โ is part of a drive in developing countries to monitor the health of infants, who often lack other forms of identification.

Russian robot escapes testing area to cause chaos on local streets
It is not every day you see a runaway robot causing traffic chaos in a city centre. The robot, named Promobot, was being put through its paces at a research lab in the city of Perm in central Russia's Perm Krai region. The robot, designed to avoid obstacles and to turn around when it reached a boundary, had been left walking around an outside yard. This is the hilarious moment a runaway robot causes traffic chaos in a city centre. The robot - called Promobot - was being put through its paces at a research lab in the city of Perm in central Russia's Perm Krai region Promobot - short for Promotional Robot - is a unique robot created by Russian scientists and is designed to work in customer relations.
Data scientist dreams up ideas and then brings them to life - JobsBlog: Life at Microsoft
Anirudh Koul's grandfather was slowly losing his ability to see. By 2014, he was having a hard time recognizing Koul's face in their weekly Skype calls bridging the vast distance between the Silicon Valley, where Koul is a data scientist at Microsoft, and the elderly man's home in New Delhi. So Koul started reading up on the challenges of vision loss and thinking about how the recent advances in deep learning, a potential-packed area of machine learning, could help give people a new way to recognize what's around them without actually seeing it. That was the modest beginning of Seeing AI. Two years later, Microsoft CEO Satya Nadella introduced the budding technology to thundering applause at this year's Build conference.
Financial Institutions Fears Of Artificial Intelligence
The Monetary Authority of Singapore (MAS) ordered BSI Bank Singapore to shut down recently on 24 May 2016. This serious action is due to their compliance oversight in money laundering which resulted in a criminal case. This is also a stark reminder of the compliance challenges that financial institutions are facing today. They had attracted millions of dollars of regulatory fines in the aftermath of the 2008 Global Financial Crisis. A distinguished law firm, Baker and McKenzie, commissioned a survey of 424 senior executives from financial institutions.
