How to be a machine learning engineer?

If the same question is inside your head, you are not alone!

Machine learning, Data Science, Cyber Security - are ever-growing industries that work at the forefront of the development of artificial intelligence in many industries ranging from retail, finance, healthcare, tech, and automobile.

But, these fields are relatively new, and most people have no idea what a machine learning engineer is and how to become one.

Nevertheless, you can rest assured because this article can help you by answering all your questions regarding how to become a machine learning engineer.

Here are the things you will learn from this article:

What is Machine Learning?

Machine learning is one of the most exciting discoveries in the field of technology.

And we use it every day in our daily life.

Don’t believe me?

We all use YouTube and Instagram in our free time.

You can notice that once you watch 2-3 dog videos on Youtube, the feed will automatically fill with suggestions for more dog videos.

But, how does Youtube know to suggest more dog videos?

Youtube does it by analyzing your watch history and predicting the type of content you like most. And it does everything by itself, without any assistance from a human.

Machine learning has been ingrained into our lives so well that we don’t even notice it.

What-is-Machine-Learning

In simple terms, machine learning gives our computers the ability to learn independently and without any assistance from an engineer.

How Machine Learning Works:

It starts with training the algorithm with datasets. Let’s say you want to teach the machine to understand what is a cat and what is a dog.

Then you have to start with a list of dog and cat photos which will work as data sets.

When the data sets are defined, the machine learning engineer starts to train the algorithm iteratively by inputting data into the algorithm to achieve better accuracy.

Who is a Machine Learning Engineer?

Machine learning engineer is the person behind building and training machine learning algorithms.

They are also computer programmers, but their focus goes beyond creating software and applications.

Their job is to create models that can take action without any assistance from users.

What Does a Machine Learning Engineer Do?

We’ve already established that machine learning engineers generally create and maintain self-learning algorithms without human intervention.

This sounds linear, but there are many things that go behind it.

  • Engineers have to run machine learning experiments using Python, R, and ML libraries.
  • Deploy ML algorithms into software and test workflow while working on optimizing performance
  • Perform foundational data science experiments such as analyzing data and understanding use-cases.

Machine learning engineers also collaborate with stakeholders such as data scientists, researchers, engineers, and product managers to understand clients’ requirements and product roadmap to provide a perfect solution.
