News in Google News

02 Jul

After several announcements, finally in the second half of May Google launched its new application, only now I have been able to take a look at the application that replaces Google Play Nwesstad, now with use of Artificial Intelligence.

The application works on using machine learning to train algorithms that scour complex and recent news stories and divides them into an easy-to-understand format with timelines, local news and stories presented in a sequence according to the evolution of the facts, for example , the start of a football match, its most important bids, the result and the consequences.

This section which are news that the algorithms think important to you have the name For You, follow 3 more sections so divided: The second section is called Manchete, where the latest news and specific topics are presented. Here is a subsection where you can choose to read the news through Full Coverage by Google, where Google splits it into items from a variety of social media sources, letting you know where and when it happened.

The third section shows favorites, such as the top topics the user usually accesses, the AI ​​has great work there, goes to the owner’s favorite sources, saves stories for later readings, and saves searches according to the location of the texts.

And finally the White Play (White Play) which is the addition of the new Google news, which allows the user to access and subscribe services with premium content in news sites.

While a part of the critique continues to duel with the old canned news schemes linked to editorial groups, the world of personalized news evolves

 

 

Personal assistants arrive at the office

27 Jun

In some doctors’ offices already use Google Home, Assistant and Translate, in addition to the indispensable Agend, whoever starts using it does not leave it any more, it avoids scheduling conflicts and warns forgetfulness, but the idea now is to integrate these environments into “Medical Digital Assit “, developed by the doctor Steven Lin of Stanford University made next to the CNBC.

According to CNBC site, the project is in the health group of the daring Google Brain project, part of Google’s division in artificial intelligence, having as its “ambitious goal” to deploy external health care trials before the end of 2018.

The main goal, however, is to assist physicians in their reports and medicals records, before beginning the studies the Stanford School of Medicine made a survey where they found that doctors lose 6 to 11 hours of their daily work to document the histories patients’ clinics, so it is often easier questions, but patient responses may be inaccurate or ignore relevant data.

The problem of accuracy is key, the CNBC website explains the difference between an interpretation and “hipo” or “hyper” can be fatal, hypoglycemia is exactly the opposite of hypoglycemia if the doctor does not check this carefully.

The first phase of this study is expected to conclude in August, Lin said both parties plan to renew collaboration for the second phase for at least a year.

Microsoft and Amazon are also reportedly developing systems similar to artificial intelligence, and the main focus remains on developing clinical reports

 

Alexa: Amazon personal assistant

26 Jun

It may not seem like a new phenomenon in technology since there are wizards like Siri, Cortana or Google Now, but the fact that this wizard is really personal, that’s why I called the others for voice assistants, is the fact that it learns and stores the data in a private cloud from Amazon Web Service (AWS).
These personal assistants although all grounded by the use of voice there are differences, they can learn from specific people habits and functions they desire, while the voice assistant, as I call Siri and Google Now now empordered by Dialogflow, as we explained in the post above, they can respond and learn from human interaction, but may, if it is desirable to organize their own database.
Alexa (because I’m the personal assistant I think is masculine, but it can be the same) is centralized in the Amazon cloud and has its own equipment that is Amazon Echo, a column always connected to the Internet via WiFi that is attentive to dialogues of its “owner”.
Streaming music services using Spotify or Pandora, you can read the news of the main newspapers you prefer, inform the weather forecast or the traffic on the way to work, can control all equipment at home that are Smart Home, including it can identify and tell about compatibility, plus its capacity goes beyond.
In addition, it promises to check basic things like solving math accounts or getting into a conversation and even telling jokes, over time this bank and this ability will evolve.
But beware, we have already written here about the myth of singularity (especially the book by Jean Gabriel Ganascia), the idea that this will turn a monster and control you is less true than to individualize and stop talking to friends and relatives

 

Make holograms real, fast and accurate

20 Jun

We have already mentioned the development of holograms in space without the need for devices that recreate the artifacts, now it is possible to do them in an ultra-fast and very precise way. Scientists at the Lawrence Livermore American Laboratory in California have developed a technique that can create complex objects in seconds, we can say using Shannon’s sampling theorem for imaging, now being three-dimensional.

This technique creates the objects in layers simultaneously, the details were published in the journal Science Advances in December 2017, there are two really important innovations there, the possibility of creating real images in ultra-fast mode using a photosensitive resin recreating 3D printing with a powerful laser which hardens this resin making it a plastic.

This can also be done with metals using electron beam and a metal powder instead of the resin, so does not need the numerous supports required for 3D printers. LLNL engineer Maxim Shusteff, who leads the study, told New Atlas: “The fact that you can make totally 3D parts, everything in one step really overcomes a problem in additive manufacturing”, now holograms can return to material parts.

Another option would be live tissue bio-printing: “We made a good first attempt,” Shusteff said, “but we have not yet taken it to the limit of its performance, so the space is open to us and others to demonstrate what this approach is able to do. “living tissue bioprinting. “We made a good first try,” said Shusteff,

If 3D printing was already heralded as a revolution, this new technique promises to further accelerate this process

 

The first quantum computer hub

30 May

The North Carolina State Unit was chosen by IBM to have the first Quantum Computing Hub (Q Hub that became part of IBM’s Network Q), as well as the first networks linking some universities.
On December 5, 1969, ARPANET joined the Research Agency of the US Department of Defense, the University of California, Los Angeles (UCLA), the Stanford Research Institute (SRI) at Menlo Park, the University of California, Santa Barbara (UCSB) and the University of Utah (photo).
Students, faculty and researchers will be able to access IBM’s 20-bit supercomputer to solve classic computing problems that would take a long time to process, now they will be done in a few minutes depending on the problem.
Bob Sutor of IBM Research said “we can not create a computer with 10% of the Earth’s atoms, but even so, with the quantum computer we can represent exactly this information”, according to a post on Techinician Online.
IBM’s plan is more audacious, with Fortune 500 companies and universities working to solve larger problems more quickly through the Q Network, while NC State will be collaborating with local organizations to solve complex equations.
NC State faculty are developing both undergraduate and graduate courses to use quantum computing to build their knowledge in anticipation of the hub’s operational debut this fall (in September).

 

Networks and global crises

22 May

Social networks are provoking an organic change in society as a whole, it is already more evident than it was ten years ago, but networking is still confused with decentralization and there are strong conservative forces calling for a new social “hierarchy”.

The perception that this or that country is a country in “crisis” more acute than others is valid, but the truth is that it is those who learn the most from the crisis that can get out of it faster, the first lesson is that there is a society more attentive, more diversified and less able to support centralized and authoritarian schemes, but why then this wave?
Precisely because the vast majority of the “silent” now reveal the true face, that of convenience and coexistence with values ​​that were only “supported” by those who suffered some form of exclusion, and I do not speak only financially, even if it is serious.
Edgar Morin points out that now the public space “gathers society in its diversity. The right, the left, the crazy people, the dreamers, the realists, the activists, the piadistas, the rebels – everyone. Abnormal would be legions in order, organized by a single flag and led by party bureaucrats. It is creative chaos, not the pre-established order. ”
All this can go back in a civil war, I agree with Manuel Castells: “civil war and social movements are incompatible!”, But social movements are now not only the masses maneuvered by unions and parties, this is what the caudillos fear, there is much distrust and according to Castells “parties are universally despised by most people,” because we know that we pay his salary (high) and do not do what they should do.
But it is necessary to save social values ​​so as not to fall into the temptation of violence and authoritarianism that is what the radicals and their masses want, Castells says “you need a lot more courage not to be violent. Being violent is easy. ”
I am in Portugal that experienced a deep crisis and still feel reflexes of it, but they learned to live together, to talk and to have a little more patience with serious social problems, but this weekend there was a mega manifestation of teachers who had salaries affected and retirement (reform here) delayed, some may be entitled only at 70´s years old.

 

Androids has dreams?

18 May

The two films of Blade Runner were inspired by the book Androids dream of electric sheep ? by Philip K Dick is reissued in 50-year commemorative edition (1968-2018) with unpublished writings: a letter from the author to the producers of Blade Runner in which prophesies the success of the production and the last interview granted by Dick, published in 1982 in the journal The Twilight Zone Magazine at the time of the launching of the film.
The exclusive preface signed by Argentine writer and journalist Rodrigo Frésan, a lover of science fiction and Dick’s work chronicling the troubled and impressive life of the author, and a brilliant scenarios they call “post-apocalyptic” by Douglas Kellner and Steven Best, professors respectively from the University of California and the University of Texas.
Add to this a postface written by the translator of the book, Ronaldo Bressane, who compares Androides with Blade Runner and comments on aspects of the work not explored in the cinema, such as environmental concern, besides the religious and metaphysical questions present in the text.
Religious and metaphysical issues are so current that they deserve an up-to-date view of what we think is our inner universe, our values and our relationship to the natural and yet transcendental world, in the non-immediate sense.
What is nature beyond nature and what is man beyond human is neither trans-nature nor trans-human only, but to look at it properly it will be necessary to have a transdisciplinary look, not to see from the side apocalyptic and pessimistic only.
Artificial Intelligence is undoubtedly an inspiration for the next few years, thinking of it is not thinking outside the spirit and human interiority, but it’s just questioning what it is, Blade Runner 2049 did this, but success was small, we preferred Robocop.
If inner life was reduced in modernity it is not due to current and upcoming advances, but due to the fact that sometimes we attribute to humans robots attitudes and not the opposite, because the current robots still have mechanical reasoning and a limited logic.

 

Agent environments and an example

17 May

The example that Norvig and Russel (2010) will give to describe what an environment in Artificial Intelligence is happy and unhappy at the same time, happy because it has become something real 8 years after the edition of the book, a taxi as a stand-alone vehicle, and unfortunate because there are already cases of accidents with autonomous vehicles.

What is called environment is described as PEAS (Performance, Environment, Actuators and Sensors) (figure on the side), whose first stage is to design the task environment.

The agent will be different from a software (a softbot or webcrawler), but it is didactic.

The suggested environment was a stand-alone taxi, which at the time was “little beyond the capabilities of existing technology,” but on page 28 will describe a robot with this function, the fortuitous side of the example as the authors say is a ” completely open” and “there is no limit to the new combinations of circumstance that may arise”. (Norvig, Russel, 2010: 40)

What performance measures will be desired: arrive at the correct destination, minimize the correct destination time, fuel consumption and wear, traffic violations, disturbances and safety to passengers and other drivers, and if there are conflicts make decisions (this is one of the reasons for the accident to protect the passengers caused a hit by a passer-by).

The next step is to map an autonomous car environment, it must deal with a variety of roads, from rural lanes and urban lanes to 3, 4 and up to 5 lanes, with lanes, other vehicles, road works, police cars, puddles, and potholes, and should interact with potential and actual passengers.

Actuators for an automated taxi include those available to a human driver: control over the engine through the throttle and control over steering and braking. some optional choices of communication with other vehicles with arrows and even horn, and with passengers who will need voice synthesizers.

The basic taxi sensors will include one or more controllable video cameras so they can see the road; you can increase them with infrared or sonar sensors to detect distances to other cars and obstacles.

The problems of safety and conviviality with human drivers is evident, but thanks to this example of success made in 2010, today we have maps, GPS, road signs, and many others advances.

The singularity and the tecnoprofetas

09 May

Before Jean-Gabriel Ganascia talked about the Myth of Singularity, the idea that machines would surpass man in human capacity, had already been analyzed by Hans Moracev in his work: Men and Robots – the future of human interfaces and robotics, careful and ethical Ganascia did not fail to quote him.

There are groups that study the ethical issues that this involves as the Center for the study of existential risk at Cambridge University, but also groups engaged in this project with University of Singularity, with weight sponsors such as Google, Cisco, Nokia, Autodesk and many others, but there are also ethical studies such as the Institute for Ethics and Emerging Technologies that Ganascia participates in, and the Institute of Extropia.

In the account of technoprofetas, the word was coined by Ganascia, a genius prejudice Kurzweil is one of the most extravagant, injected drugs in the body preparing to receive the “computational mind”, but with prediction for 2024 already spoke and now it is for 2045 to 2049 , something that is incredible for someone who is said to have no beliefs, for this fact is very distant if it occurs.

Ganascia thinks this is a false prophecy and Moracev analyzes the difficult real possibilities.

The Gartner institute that works on forecasting predicts neural computing still crawling with predictions for 20 years from now, interfaces like Amazon’s Alexa and Hanson’s Sophia, are human interaction machines that learn things from everyday language but are far from the so-called machines of a general artificial intelligence, because human reasoning is not a set of propositional calculations as they think.

One can argue more this is because people are illogical, but this according to what logic, what we know is that men are not machines and what we ask if machines are men, is the essential question that inspired the series Blade Runner, the book of Philip K. Dick “Do androids skeep dream of electric sheep” from 1968, which inspired Blade Runner.

I think dreams, imagination and virtuality are faces of the human soul, robots have no soul.

 

World created beyond the imaginary

08 May

The story of Claude Shannon, who worked in a MIT laboratory of Vannevar Bush and Alain Turing crosses through World War II, while working on secret projects, which were two sides of the same coin, unaware of one another’s project, the idea of ​​passing the language to a human code, the System X that worked Shannon, and the one of Turing that was to decipher the code of the Machine Enigma capture of the German army.

Not being able to talk about his projects, speaking at lunches and gatherings in Gödel’s Incomplete Theorem, and the idea of ​​creating a machine that could encode human thought, he said in a joke, “could be a mundane brain like that of the president of Bell Laboratories”, place of secret projects in development.

Bell Labs began as an AT & departament in Washington and later of independent labo of the project’s development (photo above).

The major obstacles to innovation initiatives stem from the mental blocks caused by unproven beliefs, prejudices and perceptions about the possibilities of technology, which are not only strongly alienating, but are inhibitors of creativity and can condemn processes of poor mental development. In spite of the irony of Shannon and Turing with the president of Bell Laboratories, there developed from the first valves, the first transistor that was awarded a Nobel Prize, the telephone systems in their most diverse versions arriving the dialed line and the use of the network for transmission over the internet, and the optimal fiber system, whose first test was done in Georgia.

Also lines of radio and television handsets, the development of the Linux precursor UNIX system, the first solar cells, several Nobel prizes and famous students passed by.

The challenge of pioneers is never simple, critics are always willing to devalue the human effort of progress, Bell Laboratories and other study centers, such as CERN and Research Institute around the world, Brazil has some of them as INPE in São José dos Campos, are central drivers of human creativity and project the future of man.
