Cientistas desenvolvem computador que imita forma de aprendizagem de humanos

Um grupo de cientistas desenvolveu um computador que imita a forma como os seres humanos aprendem novos conceitos, o que significa mais “um pequeno passo” no campo da inteligência artificial, refere um estudo divulgado hoje na revista Science.

“Estamos a tentar reduzir a diferença entre a capacidade da aprendizagem dos seres humanos e das máquinas (…) e descobrir a razão pela qual os seres humanos são tão bons a generalizar conceitos”, disse Joshua Tenenbaum, um dos responsáveis pela investigação, do Departamento de Ciência Cognitivas do Instituto de Tecnologia de Massachusetts, nos Estados Unidos.

Segundo o estudo, a principal virtude dos seres humanos é a sua “velocidade” e “diversidade” na hora de aprender novos conceitos e aplicá-los em novas situações.

“Os computadores têm dificuldade de generalizar a partir de amostras individuais” disse Brenden Lake, da Universidade de Nova Iorque e autor do estudo.

Os investigadores concentraram em aprender caracteres escritos à mão de vários alfabetos e desenvolver um algoritmo que permita a sua generalização a partir de alguns exemplos.

“O computador não tem um programa que se aplica a cada situação, mas um programa completo de diversos programas de aprendizagem que se adapta a cada circunstância”, acrescentou.

Ao comparar a capacidade daqueles computadores quando confrontados com tarefas de aprendizagem, incluindo a criação a partir de exemplos de caracteres vistos apenas em poucas ocasiões, com outros computadores e seres humanos, comprovou-se como superavam outros computadores e igualavam-se aos seres humanos.

Em muitos casos, os resultados dos seres humanos e este novo modelo cognitivo eram “praticamente indistinguíveis”.

“Na inteligência artificial não há grandes resultados. Existe um conjunto de boa ideias que funcionam. Esta é outra boa ideia, mais um pequeno passo”, disse Lake.

Learning to Code: Not A Guarantee

Learning to Code: Not A GuaranteeHey there, you probably receive tons of e-mails advertising courses, workshops or bootcamps to help you learn to code mobile and web applications, telling you how amazing the opportunity and curriculum is, how flexible they are for your schedule, and how you were guaranteed to get a job (offer or opportunity) after graduating from the program.

But it totally discounted, that I feel so many people forget, is that learning to code is hard and requires a lot of work. You can have the most beautiful website, the most charismatic instructors, the most robust curriculum, but regardless of all of these things, you need to put the time in, serious time, to be successful. Learning to code isn’t the Matrix, you can’t just plug in a USB cord and voila, you can code. Now, I’m not trying to dissuade you or scare you off—far from it! I am excited that so many people want to learn to code, but I want to make sure that they know what they are about to embark on and are doing it for the right reasons.

Coding isn’t the lowest common denominator

I’m saying all of this for a few reasons. First, there is this assumption that in order to be successful in tech, you need to know how to code. That is false. Coding is a big part of working in tech, but coding isn’t the lowest common denominator. Design, marketing, product management, and research are all critical areas in tech that don’t require coding skills at all.

You will need to evolve and develop through your entire career

The second reason, is that learning to code is a life-long learning challenge and skill. There isn’t a “finish line” at the end of the journey, only a way point to help orient you towards your next milestone or goal.  This is a skill that you will need to evolve and develop through your entire career. New platforms, new programming languages, and new ways to collaborate and communicate are all ways the practice of coding will change and evolve over time.

Programming is a group activity

The third is that coding and the broader topic of computer science contains many disciplines other than programming or coding. In the curriculum created by the College Board for the Advanced Placement program, these are defined as “big ideas” and thinking practices. Two thinking practices in particular are communication and collaboration, followed by a “big idea” of creativity. These practices extend far beyond the coding window and tap into the critical thinking skills of the individual. Programming is a group activity, but, unlike most group activities, it is asynchronous, which can be a very different style of collaboration that some might not find comfortable.

But ultimately, this gets to the real question: What do you want? Jeff Weiner and Oprah Winfrey recently had a discussion and asked that same specific question. (The specific topic comes up at 3:06 in the linked video.) It is a question not enough people ask themselves, including me. If you have decided that you “must learn to code,” have you also asked if knowing coding will make you happy? Are you learning to code because someone told you that you needed to?

Some people are learning to code for the wrong reasons. Some find coding to be so difficult and foreign to them and they struggle with every step.

Why not focus on your strengths and passions to be successful, but also, more importantly, happy. Do they feel they have only one way to get their success? Do they recognize that this is a long-term journey they are going to embark on? Do they know that coding is only part of what they will ultimately need to do?

So while a bootcamp or training program can make promises or guarantees. Those are hinging on your ability to deliver and put the work in. For the amount of work you are about to undertake, is it what you want? It can be a rewarding and amazing career, but it isn’t a guarantee.

5 Tech Skills That Will Help Any Career


The Muse logo

Almost every single job out there involves being online in some capacity. That means that, at some point in your career—this year or 30 years from now—you’ll likely have to access the back end of a company site, a blog, or an email marketing service.

Did that sentence scare you?

Don’t worry, it’s not as hard or as complicated as it sounds. Especially once you master a few of the basic building blocks. No, you won’t magically transform into Steve Jobs or Marissa Mayer overnight, but you can gain enough knowledge to talk credibly about website development and design. And that new knowledge might impress your current boss or a future hiring manager.

So, skip the Facebook stalking for a while and spend that time boosting your digital know-how instead. Here are five basics you can get started on right now.

The World We Explore – Sir Ken Robinson

Hey there,

I’ve found this Youtube video of genius educator Sir Ken Robinson a couple of years ago and bookmarked it.

Today, while doing some “bookmark clean up” on Chrome I found out why I bookmarked it on the first place, and I hope you find it equally interesting and insightful as I did.

Curiosity encourages us to push boundaries into uncharted territories. Where can our hunger for discovery take us – both outside and inside ourselves?

How Teachers and Parents Can Transform Mathematics Learning and Inspire Success

Singapore Maths Tuition

Recently, Professor Jo Boaler released her new book What’s Math Got to Do with It?: How Teachers and Parents Can Transform Mathematics Learning and Inspire Success.

The minute it came out, it became an instant best seller on Amazon. Currently, there are some issues on Math education in the United States, due to the very controversial syllabus called Common Core. Professor Jo Boaler attempts to address these controversies and give suggestions and advice to parents.

I totally agree with Professor Jo’s viewpoint that the first step to engage students in math learning is via practical means and showing them how mathematics is useful and relevant to their lives. Next is to always adopt a “growth mindset”, that no matter how weak or strong a child is in math, it is always possible to improve. Just having this mindset makes a huge difference. I took Prof. Jo Boaler’s online…

The Best Way to Learn a New Skill on the Job


Week one of my new job I was in a full-scale internal panic. Why? I was a Web Producer who only knew the very basics of coding.

Yeah, the justified kind of panic.

I certainly didn’t misrepresent my skills in what was a very short interview for a temporary position. I had online marketing experience, graphic design experience, Photoshop, Illustrator, WordPress, yes. But Dreamweaver? No. Experience designing web pages from the ground up? No. Big no.

But as they needed someone ASAP and I believe my boss was told by a previous boss that I’m a fast learner, I was hired as a 30-hour-a-week temp for four months. Now two and a half months into the job, and while I’m certainly not designing templates from scratch, I can look at a page of HTML/CSS, read it as the language it is, make adjustments and additions, and even put together a…
