It is frustrating when anything stronger than us takes away our rights. COVID-19 thought us a hard lesson when it forced us to stay in lockdown for weeks or months. I don’t believe anyone enjoyed it, even though we were in the comfort of our homes; we still had food, air to breathe, electricity, internet.

The coronavirus is still an open wound. It takes precious lives every day. Nonetheless, we are confident humankind will survive it. …

I know… Slides. Most data scientists hate building them. It is frustrating because you spend loads of time designing them and, often, the results are not as good as you expect. But don't be sad, I am here to help you make your slide-building funnier.

As you may have already noticed, slides are the most popular tool to exchange knowledge within companies (big or small ones). Without them, few people pay attention to what you have to say. Presentations are so popular because human-beings are visual learners. A measured that our brain can process images in…

Data scientists are commonly trained to measure the value of a piece of research or a mathematical technique. We read and write papers, reports, theses, and evaluate if the presented method is sound and useful to solve a particular problem. Sometimes the technique is so intriguing and fascinating that we want to explore it just because…

Data scientists are curious!

Curiosity is beneficial, but (mostly) we are not in the science business, we are doing science for business.

In the academic world, we invest in research to expand knowledge in that area. We seek the benefit for the humankind. In…


Although data science became popular with the advances in machine learning and AI, science is a much broader topic.

In the past few years, machine learning, artificial intelligence, and ultimately data science rose as the buzzword of the industry.

Of course, there is a reason for this phenomenon. New algorithms and new hardware made complex prediction systems affordable for many companies. It's not hard to find a use case in the industry about how they overcame a massive problem using a thousand-layers convolutional neural network. And really, this is a good thing.

Who never wanted a crystal ball?

Nevertheless, machine learning and artificial intelligence have been topics of research in academia for decades. They are not new. Now, they…

Quando você usa uma palavra no seu texto, ela fica na sua memória recente e você quer usá-la outra vez, e depois mais uma vez… Pelo menos comigo, isso acontece. Acho difícil evitar tal erro, mas podemos detectá-lo automaticamente.

No meu , mostrei como fiz um contador de palavras para colorir textos de acordo com a frequência das palavras. A ferramenta está disponível gratuitamente em:

Hoje, vou contar como estendi a ferramenta e usei a frequência das palavras para avaliar a originalidade do parágrafo. Olha como fica:
