Who is called a data scientist and what skills does the profession requires?

The data scientist is a new profession that today is considered key in the world of technologies and is one of the best paid. It is a person formed in the mathematical sciences and statistics that dominates the programming and its different languages, computer science and analytics .

The data science professional must also have the skills and knowledge to communicate his findings as he has them, not only in the area of ​​technology but also in the business sector. He must master the technology and databases to modify and improve the business orientation of the company for which he works .

Jose Antonio Guerrero: The best data scientist in the world

Mathematician Jose Antonio Guerrero is considered the best data scientist in the world thanks to his brilliant predictive models. These models require a lot of work and calculation of variables, but to be successful they are capable of revolutionizing the world .

For Guerrero, one of the most extraordinary examples of data science is Netflix, which in 2006 made available to the scientific data community a base of more than 100 million recommendations of films of 500,000 users and proposed that the first team in Creating an algorithm that would improve your system by 10% would receive 1 million US dollars. The work took 3 years and 40,000 teams, but today it represents a model for most online stores.
