Is Big Data Taking Us Closer to the Deeper Questions in Artificial Intelligence?
There's huge progress in AI, or at least huge interest in AI--a bigger interest than there's ever been in my lifetime. I've been interested in AI since I was a little kid trying to program computers to play chess, and do natural language databases, and things like that, though not very well. I've watched the field and there have been ups and downs. There were a couple of AI winters where people stopped paying attention to AI altogether. People who were doing AI stopped saying that they were in the field of AI. They say, "Yes, I do artificial intelligence," where two years ago they would have said, "I do statistics." Even though there's a lot of hype about AI and a lot of money being invested in AI, I feel like the field is headed in the wrong direction. There's been a local maximum where there's a lot of low-hanging fruit right now in a particular direction, which is mainly deep learning and big data. People are very excited about the big data and what it's giving them right now, but I'm not sure it's taking us closer to the deeper questions in artificial intelligence, like how we understand language or how we reason about the world. The big data paradigm is great in certain scenarios. One of the most impressive advances is in speech recognition. You can now dictate into your phone and it will transcribe most of what you say right most of the time. That doesn't mean it understands what you're saying. Each new update of Siri adds a new feature. First, you could ask about movie times, then sports, and so forth. The natural language understanding is coming along slowly. You wouldn't be able to dictate this conversation into Siri and expect it to come out with anything whatsoever. But you could get most of the words right, and that's a big improvement. It turns out that it works best with a lot of brute force data available. When you're doing speech recognition on white males, who are native language speakers, in a quiet room, it works pretty well.
eBay acquires an artificial intelligence and analytics company
Acquiring Expertmaker is part of eBay's structured data push to better organize products on its marketplace. EBay Inc. took another step this week to better organize its product data and make items easier to find when the online marketplace acquired a Swedish company focused on artificial intelligence, machine learning and big data analytics. EBay bought Malmo, Sweden-based Expertmaker, which has worked with eBay since 2010 and also has offices in San Francisco. When the transaction is final, Expertmaker employees will become part of eBay's structured data product and technology team, with founder and CEO Lars Hard joining as director, data science, according to eBay. The online marketplace continues to press its initiative to have sellers define their products using structured data, which means characterizing items in a standard way.
"SophieCo" Rise of the machines
Humanity may be wiped out by machines this century โ leading AI scientist. It took millions of years of evolution for nature to come up with something that changed the face of the planet forever โ the human brain. Now, the new mind is to be born, and the best cyber scientists will be its midwife. Artificial Intelligence is said to be just decades away from creation, and it will probably change life on Earth entirely. Some predict the coming of Utopia, where machines will help humanity fight disease, poverty and even death. But that's as others see a way more darker future, with machines rising up to eradicate humankind once and for all.
White House to launch AI push with new workshop series
The White House is planning to hold four public workshops this summer to develop plans and spur dialog about the federal government's use of artificial intelligence technologies. In a White House blog post announcing the workshops earlier this week, Deputy U.S. Chief Technology Officer Ed Felten described some of the potential use cases for AI in government, as well as some of the challenges. "In education, AI has the potential to help teachers customize instruction for each student's needs. And, of course, AI plays a key role in self-driving vehicles, which have the potential to save thousands of lives, as well as in unmanned aircraft systems, which may transform global transportation, logistics systems and countless industries over the coming decades," Felten wrote. The four planned workshops have partnerships with academic and non-profit organizations, and the discussions will feed into the development of a public report later this year, according to the blog.
Belief Merging by Source Reliability Assessment
Merging beliefs requires the plausibility of the sources of the information to be merged. They are typically assumed equally reliable in lack of hints indicating otherwise; yet, a recent line of research spun from the idea of deriving this information from the revision process itself. In particular, the history of previous revisions and previous merging examples provide information for performing subsequent mergings. Yet, no examples or previous revisions may be available. In spite of the apparent lack of information, something can still be inferred by a try-and-check approach: a relative reliability ordering is assumed, the merging process is performed based on it, and the result is compared with the original information. The outcome of this check may be incoherent with the initial assumption, like when a completely reliable source is rejected some of the information it provided. In such cases, the reliability ordering assumed in the first place can be excluded from consideration. The first theorem of this article proves that such a scenario is indeed possible. Other results are obtained under various definition of reliability and merging.
Matching models across abstraction levels with Gaussian Processes
Caravagna, Giulio, Bortolussi, Luca, Sanguinetti, Guido
Biological systems are often modelled at different levels of abstraction depending on the particular aims/resources of a study. Such different models often provide qualitatively concordant predictions over specific parametrisations, but it is generally unclear whether model predictions are quantitatively in agreement, and whether such agreement holds for different parametrisations. Here we present a generally applicable statistical machine learning methodology to automatically reconcile the predictions of different models across abstraction levels. Our approach is based on defining a correction map, a random function which modifies the output of a model in order to match the statistics of the output of a different model of the same system. We use two biological examples to give a proof-of-principle demonstration of the methodology, and discuss its advantages and potential further applications.
Announcing the winner of our second competition - Jackknife regression
The winner for our second data science competition is Tom De Smedt, biostatistician completing a Ph.D program at University of Leuven, Belgium. His special interests are in spatial statistics, environmental epidemiology, novel regression techniques and data visualization. The competition consisted of simulating data and testing the Jackknife regression technique recently developed in our laboratory, on correlated features or variables. The technique provides an approximation to standard regression, but is far more robust and deemed suitable for automated or black-box data science. The easiest version consists of pretending that variables are uncorrelated, to very quickly obtain robust regression coefficients that are easy to interpret.
India could soon use drones to transfer human ORGANS
For someone who is in need of an organ transplant, every second counts. To save more lives, a group of scientists in India have designed a new method of transportation that is much faster than hauling them in the back of an ambulance. Called, Rs 100-crore National Programme for Micro Air, the project is set to use unmanned aerial vehicles to delivery of hearts and other vital organs, cutting time by more than 50 percent. A group of scientists from India are working on a way that will transport hearts and vital organs much faster than hauling them in the back of an ambulance. Currently the team has two options: design a drone with technology to preserve organs or variants that are able to carry the organ in a special box.
'Battlefield' video game travels to World War I
While many video games are pushing their stories toward the future, the classic franchise Battlefield is stepping back to revisit the past. Publisher Electronic Arts announced Battlefield 1, the latest chapter in the military action series that will take players to the battlefields of World War I. It launches October 21 for PC, PlayStation 4 and Xbox One. The game will take place across multiple locations around the world, including France, the Italian Alps and the deserts of Arabia. Battlefield 1's story kicks off right around the start of World War I, as players "witness the birth of modern warfare."
