Computers learn to act on their own, we no longer need to write detailed instructions for performing certain tasks. Therefore, machine learning is of great importance for almost any field, but above all it will work well where there is Data Science.

The first step in learning machine learning is to become familiar with its three main forms.

Five basic steps in working with data

  • Collection. Search for channels where you can collect data, and the choice of methods for obtaining them.
  • Checking. Validation, leveling of anomalies that do not affect the result and interfere with further analysis.
  • Analysis. Examining data, confirming assumptions.
  • Visualization. Presentation of information in an understandable form: graphs, diagrams.
  • Reaction. Data-driven decision making. For example, changing the marketing strategy, increasing the company's budget.
  • The path to this profession is difficult: it is impossible to master all the instruments in a month or even a year. You have to constantly learn, take small steps every day, make mistakes and try again.

Step 1. Statistics, mathematics, linear algebra

For a serious understanding of Data Science, you will need a fundamental course in probability theory (mathematical analysis as a necessary tool in probability theory), linear algebra, and mathematical statistics.

Fundamental mathematical knowledge is essential to analyze the results of applying data processing algorithms. There are strong engineers in machine learning without such education, but this is rather an exception.

Step 2. Programming

Familiarity with the basics of programming will be a big advantage. You can make it a little easier for yourself: start learning one language and focus on all the nuances of its syntax.

Pay attention to Python when choosing a language. First, it is ideal for beginners, and its syntax is relatively simple. Secondly, Python is multifunctional and in demand in the labor market.
