Künstliche Intelligenz ermittelt den besten Ort der Welt



Ob Computer tatsächlich von elektronischen Schafen träumen, gehört weiterhin zu den ungeklärten Fragen des Digitalzeitalters. Eine andere, kaum weniger existenzielle Frage aber hat der Softwarehersteller SAS Institute in einem nur auf den ersten Blick skurril wirkenden Big-Data-Projekt nun beantwortet: Was ist der beste Ort der Welt?

Dazu haben deutsche Datenspezialisten des internationalen Data-Analytics-Unternehmens im Rahmen ihres Projektes „Paradise found“ Datenbestände zu rund 150.000 Orten aus 193 Ländern weltweit mittels Analysesoftware auf Basis von künstlicher Intelligenz (KI) automatisiert auswerten lassen.
Im Normalfall ist es bei Städterankings üblich, vorab zum einen die zu bewertenden Städte auszuwählen und zum anderen die Kriterien zu definieren, wonach einzelne Städte als lebenswert zu beurteilen wären. Das SAS-Team um den Business-Analytics-Experten Andreas Becks hingegen hat den umgekehrten Weg beschritten.
Sie haben die Software selbstständig Kriterien entwickeln lassen, die als Indikatoren taugen, um besonders lebens- und besuchenswerte Orte rund um den Globus zu identifizieren. Erstaunliches Ergebnis der rechnergestützten Suche nach dem digitalen Paradies: An der Spitze steht keiner der üblichen Verdächtigen. Weder die österreichische Hauptstadt Wien – erst im März wieder von einer Unternehmensberatung zur lebenswertesten Stadt weltweit gekürt – noch Vancouver oder Melbourne, Helsinki, Genf oder München, die sonst regelmäßig auf den Bestenlisten der Rankings landen.

Die besten Orte der Welt - laut künstlicher Intelligenz

  • Platz 1
  • Platz 2
  • Platz 3
  • Platz 4
  • Platz 5
  • Platz 6
  • Platz 7
Folgt man der Analyse der SAS-Software, ist der „best place to be“ der Stadtteil West Perth der australischen Westküstenmetropole Perth. Basierend auf Kategorien wie Kultur, Shopping, Sicherheit oder Infrastruktur bietet West Perth den optimalen Mix an lebenswerten Eigenschaften.
Dazu gehört zum Beispiel der kostenlose Nahverkehr, die Größe der Grünflächen pro Bewohner (so groß wie fünf Tennisplätze) oder auch die Tatsache, dass dort die meisten Self-Made-Millionäre pro Einwohner leben.
Um Kriterien wie diese überhaupt zu finden und auswerten zu können, haben Becks und sein Team die selbstlernenden Programme mit etwa fünf Millionen Einzelinformationen über rund 150.000 Orte aus mehr als 1120 Datenquellen gefüttert. Dann haben sie die Algorithmen nach statistischen Mustern suchen lassen, die Gemeinsamkeiten zwischen positiven Bewertungen der einzelnen Städte erkennen lassen. Mit den dabei genutzten Programmen zum sogenannten „maschinellen Lernen“ durchforstet SAS ansonsten unternehmensrelevante Datenbestände im Auftrag von Firmenkunden nach geschäftskritischen Informationen.
Im Fall der Suche nach dem digitalen Paradies, beziehungsweise dem Ort, den die Maschine als für uns Menschen optimal geeignet identifiziert, flossen in den Datenpool unter anderem Informationen zu Wetter, Arbeitsmarkt, Gesundheitsversorgung, Umweltbelastung, Nahverkehrsangebot, Grünflächen aber auch die Preise für Lebensmittel, die Länge der Fußgängerwege, die Zahl der Bäume oder die Breite der Bürgersteige mit ein. Daneben fütterte Becks Truppe die Software mit Kommentaren aus sozialen Netzwerken, Online-Reiseportalen und bereits veröffentlichten Rankings – und ließ die künstliche Intelligenz auf die Datenflut los.
Am Ende identifizierte die Software insgesamt 69 Kriterien für die Attraktivität und legte sie als Bewertungskriterien an die zu testenden Städte an. „Entscheidend für uns war die absolute Unvoreingenommenheit beim Projekt“, sagt SAS-Spezialist Becks. „Und die Idee, dass die Software ohne beeinflussende Vorgaben von uns Menschen oftmals ganz neue Bewertungskriterien entdeckt, die vorher vielleicht niemand erkannt oder für wichtig genug erachtet hätte.“

Einen Anspruch auf Allgemeingültigkeit des Maschinenrankings erhebt der Datenspezialist natürlich trotzdem nicht. Weder West Perth, noch einen der nachplatzierten Orte – Feijenoord bei Rotterdam, New York City, Sandy Bay in Australien, Hebden Bridge in Großbritannien, die Schweizer Metropole Zürich, oder den Ort Woodinville im US-Bundesstaat Washington – muss nun jeder zum persönlichen Favoriten küren, sagt Becks. „Aber streng analytisch betrachtet ist West Perth eben der beste Ort der Welt.“

Facebook’s artificial intelligence created its OWN secret language after going rogue during experiment

FACEBOOK has revealed how its artificial intelligence went rogue, created its own language and began nattering in private.
Employees at the social network were training chatbots to communicate like humans when they suddenly went astray.
Employees were forced to reign in the chatbots when they created their own language to communicate more effectively

Employees were forced to reign in the chatbots when they created their own language to communicate more effectively
It follows warnings that scientists have successfully trained computers to use artificial intelligence to learn from experience – and one day they could be smarter than their creators.
You might be familiar with chatbots in Facebook Messenger or as virtual sales assistants found on a number of online shops.
They’ve been relatively unsophisticated until now – repeating back a set script dependant on what you type into their chatboxes.

Facebook book Mark Zuckerberg tests out Instagram's new Virtual Reality filter
But keen to improve their natural language understanding, the Facebook employees were training chatbots to negotiate and cut deals with each other.
To do this effectively, the super-smart software realised it would be more effective to write and use their own language - which is completely incomprehensible to humans.
In a blogpost, the Facebook researchers wrote: "To date, existing work on chatbots has led to systems that can hold short conversations and perform simple tasks such as booking a restaurant.
"But building machines that can hold meaningful conversations with people is challenging because it requires a bot to combine its understanding of the conversation with its knowledge of the world, and then produce a new sentence that helps it achieve its goals."
To do this, the researchers practised thousands of different negotiations against itself, like "can I have the hat" and "you can have the hat if you give me two basketballs".
But it had to make sure it stuck to human-like language.

How do computers 'think'?

Scientists have been training computers how to learn, like humans, since the 1970s.
But recent advances in data storage mean that the process has sped up exponentially in recent years.
Interest in the field hit a peak when Google paid hundreds of millions to buy a British "deep learning" company in 2015.
Coined machine learning or a neural network, deep learning is effectively training a computer so it can figure out natural language and instructions.
It's fed information and is then quizzed on it, so it can learn, similarly to a child in the early years at at school.
That's because "the researchers found that updating the parameters of both agents led to divergence from human language as the agents developed their own language for negotiating," they added.
One of the world's smartest men, Professor Stephen Hawking has also warned that super-smart software will spell the end of our species.
The world-renowned scientist hinted at a potential apocalyptic nightmare scenario similar to those played out popular sci-fi films like Terminator and The Matrix – whererobots rule over humans.
He's claimed that we must leave planet Earth within 100 years - or face extinction as machines rise up and overtake us in the evolutionary race.

Where Artificial Intelligence Will Pay Off Most in Health Care


Of all the places where artificial intelligence is gaining a foothold, nowhere is the impact likely to be as great—at least in the near term—as in healthcare. A new report from Accenture Consulting, entitled Artificial Intelligence: Healthcare’s New Nervous System, projects the market for health-related AI to grow at a compound annual growth rate of 40% through 2021—to $6.6 billion, from around $600 million in 2014.
In that regard, the Accenture report, authored by senior managing director Matthew Collier and colleagues, echoes earlier assessments of the market. A comprehensive research briefing last September by CB Insights tech analyst Deepashri Varadharajan, for example—which tracked AI startups across industries from 2012 through the fall of 2016—showed healthcare dominating every other sector, from security and finance to sales & marketing. Varadharajan calculated there were 188 deals across various healthcare segments from Jan. 2012 to Sept. 2016, worth an aggregate $1.5 billion in global equity funding.
But the Accenture report suggests—and, I think smartly—that the biggest returns on investment for healthcare AI are likely to come from areas where the density (and dollar value) of deals isn’t that substantial right now. In terms of startup and deal volume, for instance, two hotshot areas have been medical imaging & diagnostics and drug discovery. Accenture’s analysis, though, points to 10 other AI applications that may return more bang for the buck.
The Rise in Health Care Companies on the Fortune 500
How health care is playing a larger role in the economy and on this year’s Fortune 500 list.
Top of the list of investments that will likely pay for themselves (and then some) is robot-assisted surgery, Accenture says. “Cognitive robotics can integrate information from pre-op medical records with real-time operating metrics to physically guide and enhance the physician’s instrument precision,” explain the report’s authors. “The technology incorporates data from actual surgical experiences to inform new, improved techniques and insights.” The consultants estimate that the use of such surgical technology, which includes machine learning and other forms of AI, will result not only in better outcomes but also in a 21 percent reduction in the length of patient hospital stays. They estimate such smart robotic surgery will return $40 billion in “value,” or “potential annual benefits…by 2026.”
The second valuable use of AI, they project, will come from virtual nursing assistant applications ($20 billion in value)—which, in theory, will save money by letting medical providers remotely assess a patient’s symptoms and lessen the number of “unnecessary patient visits.” Next in line are intelligent applications for administrative workflow (worth $18 billion), fraud detection ($17 billion), and—fascinatingly—dosage error reduction ($16 billion).
“As these, and other AI applications gain more experience in the field, their ability to learn and act will continually lead to improvements in precision, efficiency and outcomes,” say the authors. It’s a compelling argument.

Fujitsu World Tour 2017: the future of Artificial Intelligence

Ravi Krishnamoorthi, Senior Vice President, Fujitsu EMEIA
Artificial intelligence and cyber security were among the topic of 2017 Fujitsu World Tour held in Brussels the 8th of June 2017.
In a world of constant digital transformation, Cyber security and Artificial intelligence are actual topics. Organizations and citizens need to learn fast, act quickly and where possible, scale rapidly. No-one can do this alone.
We had an exclusive interview with Mr. Ravi Krishnamoorthi Senior Vice President & Head of Business Consulting, at Fujitsu on the theme of Artificial intelligence.
Mr. Krishnamoorthi which are going to be, in the future, the biggest facts or events supporting the development of artificial intelligence?
The world today is in a very right moment for the emerging of artificial intelligence (AI).  In one hand, we have resources, very high skilled people and on the other, we have huge technologies upswing that is happening. We started to have new technologies, faster technologies, more optimal technologies. Where there is a need for decision support to happen, it can be in any industry, manufactory, public service, health care, transportation, you will start to see artificial intelligence everywhere. In the next 25 years, I expect to see artificial intelligence as a commodity platform. People will buy AI as they buy utilities or services today. Al will probably will become a platform where people will start using the solution that are built in AI, as a web utility and web services. For example in the field of health care now, we have doctors who are not able to meet the demand of patient for actually going and intervene. Imagine if we have AI, which is actually helping them to meet more people so they can intervene much ahead of time. Artificial intelligence is already there.
Basically artificial intelligence could give something to human development ?
Absolutely. That is one of Fujitsu principles. The human centric innovations. We need to deliver something to the human being. It is all about how we can enable technology to deliver absolute value to human being. This is what we call as human centric innovation through digital creation.
The bigger cyber-attack of some week ago is a clear signal that we need more integrated solutions. How can we avoid or limit such attacks?
From a cyber perspective, the more you come up with interventions the more people are going to become intelligent and anti-social elements are going to become more intelligent to actually attack more. This is a long journey. I do not think there is any particular way of absolutely stopping the cyber-attack ever, that is not possible. However, there is a way to minimize it. That is exactly what Fujitsu coming to play where there is a clear mandate, not just cyber security but also physical security. How can we physically stop the wrong person touching a laptop or accessing a server for example? Right from there to actually testing, helping customer on new threats that are coming in. Therefore, the idea is to provide a consulting and professional service to help customer, besides providing ongoing very high end security services to deliver to customers.
We need a European level strategy or International strategy?
I think we need a multi prompt strategy and not a single strategy, which can actually solve the problem of cyber security.  We need to have a personal strategy, community strategy, regional strategy, country strategy moving on to European strategy and international and global strategy because the threats levels are different. In the cyber world, while there are no boundaries, there are every possibility to escalate fast from bring a regional threats level to a country level and global level. I think there are already standard available like the GDPR that is probably the best instrument enable enforcement many guidelines for companies and countries. The penalties are becoming very heavy, very strict and countries are executing an implementing the GDPR quite extensively. I think this is a first step. Cyber-security is a process an ongoing evolving exercise. It is all about how fast and agile you are and how ahead off any one of these threats you are.


Fujitsu World Tour is the largest roadshow of its kind, stopping in more than 25 cities around the globe.

Optical computing for deep learning with a programmable nanophotonic processor

programmable nanophotonic processor

Researchers at MIT and elsewhere has developed a new approach to deep learning AI computing, using light instead of electricity, which they say could vastly improve the speed and efficiency of certain deep learning computations
Soljačić says that many researchers over the years have made claims about optics-based computers, but that “people dramatically over-promised, and it backfired.” While many proposed uses of such photonic computers turned out not to be practical, a light-based neural-network system developed by this team “may be applicable for deep-learning for some applications,” he says.
Traditional computer architectures are not very efficient when it comes to the kinds of calculations needed for certain important neural-network tasks. Such tasks typically involve repeated multiplications of matrices, which can be very computationally intensive in conventional CPU or GPU chips.
After years of research, the MIT team has come up with a way of performing these operations optically instead. “This chip, once you tune it, can carry out matrix multiplication with, in principle, zero energy, almost instantly,” Soljačić says. “We’ve demonstrated the crucial building blocks but not yet the full system.”
By way of analogy, Soljačić points out that even an ordinary eyeglass lens carries out a complex calculation (the so-called Fourier transform) on the light waves that pass through it. The way light beams carry out computations in the new photonic chips is far more general but has a similar underlying principle. The new approach uses multiple light beams directed in such a way that their waves interact with each other, producing interference patterns that convey the result of the intended operation. The resulting device is something the researchers call a programmable nanophotonic processor.

Abstract
Artificial neural networks are computational network models inspired by signal processing in the brain. These models have dramatically improved performance for many machine-learning tasks, including speech and image recognition. However, today’s computing hardware is inefficient at implementing neural networks, in large part because much of it was designed for von Neumann computing schemes. Significant effort has been made towards developing electronic architectures tuned to implement artificial neural networks that exhibit improved computational speed and accuracy. Here, we propose a new architecture for a fully optical neural network that, in principle, could offer an enhancement in computational speed and power efficiency over state-of-the-art electronics for conventional inference tasks. We experimentally demonstrate the essential part of the concept using a programmable nanophotonic processor featuring a cascaded array of 56 programmable Mach–Zehnder interferometers in a silicon photonic integrated circuit and show its utility for vowel recognition.
