I started in Data Science back in 2015. It was not an intended move but the answer to the needs of my employer. I was working for a company providing automation services to Spanish corporations and we had the need to leverage data to automate complex tasks whose rules could not be easily hard-coded. I had recently graduated as an engineer in the middle of a terrible economic crisis, had some statistical modeling knowledge and was proficient using MATLAB. In 2015 there was not specialized Data Science degrees or boot-camps to jump-start in the field (at least, in Spain) and the naturally closest studies you could have were, in this order: Mathematics (in Spain with a strong focus in becoming a teacher/professor in the public education system) or Software Engineer (most of them more interested in App Development or creating the new Uber of "X" than in boring Data Science stuff back then).
The editors at Solutions Review have compiled this list of the best machine learning certifications online to consider acquiring. Machine learning involves studying computer algorithms that improve automatically through experience. It is a sub-field of artificial intelligence where machine learning algorithms build models based on sample (or training) data. Once a predictive model is constructed it can be used to make predictions or decisions without being specifically commanded to do so. Machine learning is now a mainstream technology with a wide variety of uses and applications.
Data Science is a big deal these days! So it stands to reason that you might want to learn it because of its amazing potential and popularity in the technical market. But you don't need to spend thousands of dollars on getting a university degree to learn Data Science. It's even predicted that "armchair data scientists" who don't have any formal qualifications in Data Science but the skills to analyze data will become even more popular than "traditional data scientists". So you can easily learn the basics of Data Science from online courses and then build upon those basics by practice.
