According to Indeed, the average salary for a machine learning engineer is $149,750 per year in the United States and similar high salaries in other countries too. With more and more organizations making machine learning a key pillar for innovation and driving growth, there is huge scope for smart and enthusiastic Machine Learning engineers. It is one of the fields having great career prospects, both in terms of the compensation offered as well as considering the variety of challenges available.

What is Machine Learning?

Machine learning is the fastest-growing subfield of artificial intelligence, where systems have the ability to “learn” through data, statistics, and trial and error in order to optimize processes and innovate at quicker rates. Learn Machine learning is giving computers the ability to develop human-like learning capabilities that are allowing them to solve some of the world’s toughest problems, ranging from cancer research to climate change.

Machine Learning facilitates a system to learn from examples and experience without being explicitly programmed. Hence instead of writing code, what you do is you feed data to the generic algorithm, and the algorithm/ machine itself builds the logic based on the given data. Thus, Machine learning is the science of enabling computers to function without being programmed to do so.

By combining software engineering and data analysis, machine learning engineers enable machines to learn without the need for further programming. As a machine learning engineer, working in this branch of artificial intelligence, you’ll be responsible for creating programs and algorithms that enable machines to take actions without being directed. An example of a system you may produce is a self-driving car or a customized newsfeed.

This branch of artificial intelligence can enable systems to identify patterns in data, make decisions, and predict future outcomes. Machine Learning can help companies determine the products they’re most likely to buy and even the online content they’re most likely to consume and enjoy. Machine Learning makes it easier to analyze and interpret massive amounts of data, which would otherwise take decades or even an eternity for humans to decode.
