Por que acredito que no Brasil estamos entrando em uma bolha de Data Science?

TL;DR: Faça uma avaliação racional e pragmática baseada em fatos e informações de mercado antes de escolher uma mudança de carreira ou até mesmo alternativas de investimento em qualificações em Data Science & Machine Learning.  Eu sei que nos dias de hoje o que eu estou falando pode parecer ser contraintuitivo, ao mesmo tempo que temos empresas anunciando que vão contratar 100 cientistas de dados em um único ano (mesmo sem nenhuma justificativa sólida do porque e principalmente do retorno esperado com essas contratações), ou quando o volume de buscas em “ciência de dados” aumenta em mais de 50% em menos de 3 anos, ou em uma busca simples podemos encontrar mais de 1.500 vagas disponíveis no LinkedIn.

RecSys 2019 – Recommendation in Multi-Stakeholder Environments (RMSE) and 7th International Workshop on News Recommendation and Analytics (INRA 2019) in RecSys 2019

Once that you’re in a conference, the first thing that you do is certainly go to the main talks and see the presentations of big companies, look for the big cases, hang out with authors of great papers stating the SOTA and so on.  This is the safest path and probably most of those cases will have press releases discussed in media or subject in blogposts and you can have access to this before almost everyone.  However, one thing that I think is very underestimated in conferences are the workshops.

Security in Machine Learning Engineering: A white-box attack and simple countermeasures

Some weeks ago during a security training for developers provided by Marcus from Hackmanit (by the way, it’s a very good course that goes in some topics since web development until vulnerabilities of NoSQL and some defensive coding) we discussed about some white box attacks in web applications (e.g.attacks where the offender has internal access in the object) I got a bit curious to check if there’s some similar vulnerabilities in ML models.  After running a simple script based in [1],[2],[3] using Scikit-Learn, I noticed there’s some latent vulnerabilities not only in terms of objects but also in regarding to have a proper security mindset when we’re developing ML models.  But first let’s check a simple example.
