Big Data, Inteligência Artificial, Machine Learning e o que Hollywood não vai te contar

Big Data, Inteligência Artificial, Machine Learning e o que Hollywood não vai te contar

Terra, 2020. O mundo sofreu uma grande mudança com o poder que as máquinas obtiveram. Elas passaram a interferir no dia a dia das pessoas, dão opiniões em decisões, extraem informações dos seres humanos para uso próprio e tudo parece acabado para a sobrevivência da nossa espécie. Esse poderia muito bem ser a sinopse de um filme B de Hollywood, talvez um blockbuster (Transcendence prova isso). Eles gostam muito desse tom dramático. Embora seja uma visão interessante, não é única. Eu tenho uma visão mais otimista sobre o assunto. Segundo estudos do International Data Corporation (IDC), em 2020 chegaremos a 40 mil exabytes, o equivalente a 100 milhões de vezes a quantidade de livros já escritos hoje. Não precisamos esperar chegar em 2020 para tirarmos proveito do que chamamos de Big Data. Essas duas palavras acabam servindo de guarda-chuva para uma série de outras que estão mudando a forma de nos relacionarmos com o mundo. Nessa palestra eu pretendo mostrar alguns insights de como já podemos tirar proveito de coisas como inteligência artificial e machine learning e o que precisamos entender para lidar com tudo isso.

  1. "I think we should be very careful about artificial intelligence.

    If I had to guess at what our biggest existential threat is, it’s probably that. So we need to be very careful with artificial intelligence. I’m increasingly inclined to think that there should be some regulatory oversight, maybe at the national and international level, just to make sure that we don’t do something very foolish. With artificial intelligence we’re summoning the demon. You know those stories where there’s the guy with the pentagram, and the holy water, and he’s like — Yeah, he’s sure he can control the demon? Doesn’t work out."

  3. "I am in the camp that is concerned about super

    intelligence. First the machines will do a lot of jobs for us and not be super intelligent. That should be positive if we manage it well. A few decades after that though the intelligence is strong enough to be a concern. I agree with Elon Musk and some others on this and don't understand why some people are not concerned."

  5. "The development of full artificial intelligence could spell the end

    of the human race. Once humans develop artificial intelligence, it would take off on its own, and re-design itself at an ever increasing rate. Humans, who are limited by slow biological evolution, couldn't compete, and would be superseded.”

    the ability to learn without being explicitly programmed.
  10. A computer program is said to learn from experience E

    with respect to some class of tasks T and performance measure P, if its performance at tasks in T, as measured by P, improves with experience E. Tom Mitchell (1997)

    about how to make people click ads, … That sucks.
