The Machine Learning

30 Sep

Trend Even from the 21st century artificial intelligence was in a great crisis, could do a lot of logical reasoning, treat and rationalize equations, make inferences, but the volume of “human” data was small, the emergence of the Web and the adhesion of billions. of people enabled a new scenario: Big Data, a large amount of human data.

This large and complex data can be processed with large-scale accurate results, so that it can be processed by machine so that the machine “learns” trends, this (not by) machine learning is called “Machine Learning”.

With this it is possible to identify opportunities and avoid mistakes such as insisting on “logical” discourses but out of trend, it is not a question of going into fashion, but rather identifying it to correct it or propose other alternatives, and that is the opportunities Real.

Big data identifies data patterns, creates and analyzes the connections between them, and makes the execution of a given also smarter, whether or not it can rely on human supervision. In these two types, supervised and unsupervised, machine “learning” will always be essential, in supervised there is human interaction controlling the input and output of data and thus directly interfering with machine training, while in unsupervised algorithms use deep learning to handle and solve complex tasks without human intervention.

An important algorithm for semantic searches was made by a GitHut team: Hamel Husain. Ho-Hsiang Wu and Tiferet Gazit, and two Microsoft researchers: Miltiadis Allamanis and Marc Brockschmidt, who assess the state of evolution of semantic search algorithms and even make the code available through the GitHub site.

The unspiritualized asceticism

23 Sep

Not a phrase of any theologian, not even of a religious person, is the philosopher Peter Sloterdijk, who besides being one of the most read and controversial of our time, had and has had enormous influence on Byung Chull Han, author well known for many works, but perhaps his main work is “The Society of Tiredness,” Sloterdijk coined “despiritualized asceticism.
It is in his book “You can change your life” not yet published in Portuguese, besides a well done sentence, after all he also works immunology, a life of exercises, which is one of the characteristics of modern man, I do not have a spiritual exercise If you do it systematically and consciously, you indulge in “exercises” to find immunology.
I also found, I was actually expecting this because it is a consequence of his thinking, a worldview, in an interview and not in books, I read his sentence: “Ancient philosophy did not place the accent on the rationality of the world, but on the need to conduct a life regulated according to cosmic prescriptions of being: his concern was above all ethical “.
He hoped because his book “Critic of Cynic Reason” is blunt and even difficult.
He explains in this interview his main concept which is the anthropotechnique: “the beginning of my book, I spoke mainly of repetitions”.
The critical point in the history of civilization is, in my view, represented by the emergence of explicit exercises: the human being, as such, lives in repetition and gives form and content to his life through a more or less conscious ritualism, made up of exercises. repetitive”, so ritualism is part of human life, but spirituality is not.
Sloterdijk’s “spirituality” is not imbued with religiosity, since it is increasingly linked to financial, political and even ideological appeals, the true form of change that the world, and man himself needs, is one capable of revalue life, the Being itself and depends on an inner action.
Says Sloterdijk in the interview, contrary to the categorical imperative upon which the current idealistic asceses move: “The imperative that I propose is, on the contrary, a transforming imperative: human beings sensitive to their appeal should start working on themselves”.
To live is to prepare oneself, to transform oneself, to access the status of the wise, to respond to the vertical tension that requires modifying one’s existence”.
The emptying of Being, a project of contemporary idealism is empty of spirituality, its appeals to ethics, go through the construction of power, what Foucault called biopower, and what Chull Han, Sloterdijk’s disciple says, has now moved to psycho-power, a form of “control” by an excess of bad information in the idealistic sense.

 

Change thinking and teach to live

05 Sep

When we propose a model that is not that of the world of life, Husserl made a philosophy of it, his Lebenswelt, Habermas made it a sociology, Heidegger and Gadamer incorporate it in his thoughts, but the end that is life if not learning.
The central problem of seeking a “clearing” is that we create models too far from life, from its defense including nature, dignity and living itself, we are in a Yellow September, whose theme is none other than to say that it is worthwhile. It is worth living.
thought”.
Clinging to already outdated methods and models, logicists and neopositivists, it is not pointed out “the nature of knowledge, which itself contains the risk of error and illusion” (MORIN, 2015, p. 16).
The great complexity theorist proposes, first of all, a return to philosophy (in the sense of primary thinking) in its Socratic condition of dialogue, Aristotelian (in the sense among others, of the organization of information), Platonic (questioning of appearances), and even pre-Socratic (questioning the world, inserting knowledge in modern cosmology), finally cannot teach life without knowing that it has dilemmas, errors and options.
Morin, who could boast of wisdom by age, by intense intellectual activity, from the pedestal of those full of certainties, no doubt or misconceptions that we see parading through the gyms and public stands of devouring and unquestioning media.
Morin seeks to “conceive the instruments of a thought that is pertinent because it is complex” (Morin, 2015, p. 23), and we see the barbarism of dogma and little elaborated certainties.
Ready-made phrases, self-help manuals, (mainly economic) laissez-faire, rudeness, and ideological hysteria deepen today’s cultural, humanitarian, and social crisis.
It scares me that book readers are so sure with so little thought, in fact criticism of thought grows and the praise of ignorance seems to win any argument.
Morin encourages us and brings us to a still visible and possible future, his lecture at the Frontier of Thought (2016) is a hope and a deepening that sheds new light.

Óbidos, the Portuguese medieval city

22 Jul

The city of Óbidos, considered one of the 7 wonders of Portugal, the little towns are villages, although they have municipal council, are linked to a district and this city is linked to the district of Leiria, in the province of Extremadura, the center has 2200 inhabitants , but the whole region has almost 12 thousand.

The city has a castle with walls, considered one of the 7 wonders of Portugal, where you can live with medieval aspects, this week for example, there is the medieval festival, but the project “Literary Village” turned Óbidos into Literary City by UNESCO.

It is 80 kilometers from Lisbon, has three cross streets, Rua Direita, Rua do Facho and Josefa d’Óbidos, a tribute to the main baroque artist of the city, post tomorrow. There are vestiges that Óbidos is inhabited from primitive peoples, its logistics near the sea, the climate and the fortification of defenses were in this region also the Romans, the Muslims and in the year 1148, after the conquest of Santarém and Lisbon by D. Afonso Henriques, was also taken from the Arabs.

There is near the Lagoa (lagoon) d’Óbidos, it is possible for the real road, being like lagoon easier of defense and also with exits to the sea in several points, going from the Beach of Bom Sucesso to the Praia da Foz do Arelho (Beach of the Foothills of the Sea Arelho), bypassing the Lagoon.

As for the name, the word comes from the Latin Oppidus, which means “fortified city”, there are signs that the emperor Cesar Augustus erected the city in the late 1st century BC. This week Óbidos holds the Medieval Festival, and there will be a doctoral meeting of Digital Art from the Open University.

The video below shows the Medieval Festival of last year:

Black holes and worldview

16 Jul

Until recently the material world comprised only the so-called baryonic matter which is 4% of the only one, which is the material that most people know, with the dark energy and mass appeared the “black holes” that are actually black bodies.
Scientists still believe from Einstein’s theory that black holes suck objects and everything around them, including light itself, now a new phenomenon can change that. This process of sucking is called accretion, so there is a hot plasma that orbits around the black hole and is sucked by accretion, but this can also occur in bodies, and now a body that resists this accretion has been sighted. of accretion body, by the junction of material around it in the process of protoplanet formation.
The GRS1915 + 105 object is actually two stars a black hole (the body whose gravity prevents anything from escaping, hence being called the hungry), and a very modest star for the proportion of the black hole, similar to the sun. If compared to the 13 billion light-years of the observable universe, it is close to the Earth, because it is 40 thousand light-years away, what intrigues is that the black star (the name looks better than a hole) is that the star -star is not sucked though called accretion.
Next to an American laboratory, the star was observed using an ESO (Southern European Observatory) telescope, forming a trio from Germany and Chile that captured the light from the companion star of the black hole and determined to ” technical “:
According to a paper published in Nature, astrophysicist Charles Bailyn of Yale University, USA, said that the calculations are still not very accurate in size, mass and energy: “It is computed using very simple observations and calculations based only on the laws of orbital motion of Kepler, who are already known and have been trusted for centuries. ”
The mass is one of the problem points, in addition to the aspect of the addition, according to Jochen Greiner of the Astrophysical Institute of Potsdam, Germany, one of the authors of the article: “I would be very surprised if the mass was so wrong that theories applied.
By that I mean that I am convinced that theories have missed the mark: “In fact it is already suspected that what we think about mass is something quite different, by the theory of the current relativity, until the particle of Highs and the existence of the black holes they seemed to confirm, since the universe copernican and newtonian were surpassed.
Now if the mass is the one that is measured, and the hole does not suck it, it means that there will be a new worldview, where mass and matter must be re-conceptued.

 

World and the Post 2015´s Agend

11 Jul

When the UN organized its Post 2015 Development Agenda, it appeared that civil society organizations were moving towards a greater focus on poverty and hunger, urban planning and education, nuclear disarmament and women’s empowerment, others subjects related to the person, the struggle for greater perks and powers, the return of nationalism moved in the opposite direction.
UN Secretary-General Ban Ki-moon said in September 2014 “Our world needs more wind and solar energy. But I believe in an even stronger source of energy, people’s power”, the path seemed safe and was not, one can now evaluate the error.
The numbers that preceded the conservative turnaround were still “very unequal” in Latin America, Eduardo Frei affirmed that the Chile that governed from 1994-2000, with several initiatives that promoted democracy and social justice, had reduced poverty by 38.6% to 7.8% of the population, and extreme poverty from 13% to 2.5%, but by 2015 Latin America had another profile, despite GDP growth from 2015 to 2018 (photo above).
It was still a region “more unequal” than another, of its 600 million inhabitants still 167 million lived in poverty and 71 million in extreme poverty, this contrast reveals a dangerous and deep social gap, according to the own Frei in 2015.
Regarding the future, Frei affirms that the struggle against poverty and inequalities demanded another effort on an ethical basis, and at this crossroads, it would be time for governments to give greater impetus to the “moral movement” that did not happen.
Juan Somavia, former Director of the International Labor Organization, said in the post 2015 agenda that a good basis for negotiations would be: “the document reflects an extremely ambitious vision with its 17 goals and 69 indicators centered on the concept of sustainable development focused on people and eradicating poverty, “saying that UN political support was critical.
In 20th birthday of UN Millennium Development Goals (MDGs), which was adopted in 2000, said that the problem of poverty eradication was echoed by the UN’s Economic and Social Council (Ecosoc) : productive employment and social integration have been excluded, and it is not mere coincidence. And social integration is a broader concept when we think of global citizenship.

 

Fraternity, worldview and religion

05 Jul

I do not know the religion of the captain of Sea Watch, but the fraternal worldview of captain Carola Rackete (picture), unjustly imprisoned and brought to trial and released only these days, is undoubtedly the only real manifestation of worldliness in the contemporary world.
The press reported little, the Italian authorities raged against the captain’s “rebellion” to rescue shipwrecks and dock in Lampedusa in Italy, against the determination of the local maritime police, but this is the true brotherhood and religion of seeing all peoples as deserving of the same fraternity and respect.
Captain Rackete has been accused of crimes of resistance or violence against the Italian warship and attempted shipwreck for having collided with a patrol of the Financial Guard (Maritime Police of the Italian borders), and the European newspapers that always boast of any attitude in Latin America or Africa has barely reported Rackete’s arrest.
Yet the old colonialist view of looking disdainfully at the rest of the world, which is not just the American, remains and little look at its crimes and atrocities, especially against other peoples and nations that have a different worldview from Europe.
They do not recognize the penumbra and the blindness that they live, not even the worldview itself is very clear, besides the political and economic interests, little or nothing remains of a respect for other peoples and cultures, and little recognizes the own decadence and crisis of thought.
The arrogance of a limited worldview, despite its origin in Christianity, holds true for much of European thought, it is a fact that there is resistance and protesting groups, to the seemingly fraternal worldview of Europe, that biblical saying about Pharisaism in the time of Jesus , Luke 10: 12: “I tell you that on that day Sodom will be treated less severely than this city,” referring to people who rejected the fraternal Christian message.
Of course, one can only speak of a Christianity with a worldview of respect and true brotherhood with all peoples and cultures, for the rest is Pharisaism and cultural pride.
The contemptuous look at the peoples suffered, exploited and colonized is still stigma of our time, is still the result of a culture of domination and exploitation of peoples and nature.
Sea-Watch captain Rackete speaks after release from house arrest:

 

Michel Serres dies

03 Jun

I get the news in the morning of the 1st. of June working at home, Michel Serres passed away, I remember several things of him that I gave in class for having appreciated by the new technologies and to make analyzes less pessimistic of this aspect.
I also remember his words about Hiroshima, who affirmed it as the sole objective of his philosophy, in the sense of peace, of course, he said that he had no influence from thinkers, but he was guiding nothing less than Bachelard, he lived with Jacques Monod, and did a published interview with Bruno Latour.
In this interview she stated: “it is carnally formed in this atrocious environment and has remained, since then, removed from all politics: power continues to mean only corpses and tortures to it”, the problem of violence has always been its main problem and hence its work .
He did not follow the traditional French epistemology that in his view is based on the separation between “sciences” and “humanities”, his perspective was to create a bridge between one field and another, the primacy of the course on the discourse (see that there is difference) , in short the search for a generalized theory of the place.
He wrote in The Leibniz System: “Through the most distant regions there is often an underground relationship that intuition alone can not attain, nor can immediate knowledge or discursive knowledge, but which can be attained, by a pure and refined formalism … The aptitude to the diverse is proportional to the initial purity.”
Alongside Michel Foucault, in the early days of the University of Vincennes (Paris-VIII) in 1968, he formed a generation of researchers and thinkers who had him as a great teacher.
Among the faceted ones of Serres, the one of historian of the sciences, in “Elements of History of Sciences” (1989) was revealed. Under his direction worked Authier, Isabelle Stender, Bruno Latour and Pierre Lévy, just to mention what is best known in Brazil.
He saw in the new technologies not a curse that cushioned relations, they were dampened by modernity and non-originating knowledge, he affirmed that a new Pedagogical Society is yet to be born.
He said in a prophetic tone, that our communications world is aging, giving birth to a pedagogical society, that of our children, where continuing education will continue for the rest of our lives, an increasingly rare work.
The universities at a distance, everywhere and always present, will replace campuses, closed ghettos for rich adolescents, concentration camps of knowledge … “(SERRES, 1995, p 56).

The discovery and the sound of pulsars

04 May

Supernovae are massive explosions of stars that until 1932 did not have many explanations, although they are observed and studied by astronomers.
Walter Brade and Fritz Zwicky sought the explanation when the subatomic particle called neutron was discovered so they understood that the answer was this, a neutron star.
It is a dense nucleus, as if two suns compressed in a space of the region of the great Sao Paulo of Brazil, but the explanation does not end there.
In 1967, the doctoral student Jocelyn Bell, captured in a radio astronomy equipment a weak pulse coming from a part of the sky with extreme precision, the house 1.3 seconds it repeated, it seemed an intentional signal of somebody or of and some civilization thought his counselor, but it was the discovery of pulsars.
Two important consequences of observation: to the extent that this star collapses its rotation increases greatly, and the other, is that collapse carries along with it the magnetic field forming a dense nucleus that spurs an energy beam dense to the space as pulses.
Russian scientists, capturing the flow of 10 pulsars, have created a song that along with other sounds of the universe form a great symphony of the creation and expansion of the universe.
Watch the video made by Russian scientists last month:

 

Poetry, Notre Dame and Ignorance

16 Apr

I was preparing to write something about the first volume of Otto Maria Carpeaux on Western literature, curiously I dwell on the passage: “‘lirism’ is the true name for the divine and human order in the world of Sophocles, symptoms of a precarious balance because purely aesthetic “(Carpeaux, 2012, p. 49), which speaks of lyricism in Sophocles, the fire of Notre Dame robs me of lyricism, and certainly not only aesthetic but historical.
Certainly there will be some who think that they are stones and museums, the little appreciation for the religious question touches me, but I understand, but no appreciation for history, the first arches that extended the ceiling of the Gothic cathedrals, an engineering work that lasted almost 300 years, that used various styles of architecture that could be reviewed and understood, etc.
There is militant ignorance, appeals to practice, objectivism (which robs any lyrical or poetic possibility), what Byung Chull Han calls the culture of the “smooth”, flat, without wrinkles or details, which wants to abolish any environment, enhances or poetic license, the “challenge” culture.
I saw the works of Gaudi in Barcelona the contemporary opposite of the culture of the flat, a poetry, lyricism and a mystique made of stone as he intended, the internal lights of the Sagrada Familia are a spectacle to the part, it is not the digital that abolished this, much before modern objectivism.
Ignorance beyond questioning any concept, philosophy or theory, in addition to a pseudo appeal to practice, objectivity or any other argument, in fact without good method none of this can be successfully achieved, this ignorance has become militant and I wonder if would not be able to destroy mankind’s patrimony.
The Islamic State did this in Palmyra, but do not we do the same in our instrumentalizing, ideologized and militant practice, in fact, there is today a militious ignorance.
I want to imagine that the fire of Notre Dame was not a criminal, because it does the same thing as terrorism by destroying history, culture and the possibility of future generations understanding the long road that humanity has gone through, it is not possible to have a promising future by ignoring the past, not only the deeds, but also the mistakes and misunderstandings.
I accept this momentary death, this is my easter and easter of history, but I believe in future and in the culture.
