Complete Guide To Become A Machine Learning Engineer​

Can you say your computer is intelligent?

So, the answer is NO. Our computer is fast, it can process data and analyze it but it lacks common sense. 

Every complex calculation can be solved with it but it cannot use common sense like us or can think like us. 

So basically if your computer by any means gains that common sense or can make its decision without human interference based on data it collects, that is called machine learning.

Machine learning is how the computer analyzes your data and notes the pattern and then makes a decision to bring it into action. Therefore, in Machine Learning artificial intelligence is developed based on experience.

Generally, Machine Learning is a subset of AI. You are using it unknowingly. Have you ever wondered how you get a similar recommendation of videos on social sites or YouTube? This is machine learning. It uses statistical methods.

Interest in Machine Learning has taken its peak when a Harvard Business Review article named “Data Scientist” said it as “The sexiest job of the 21st

The exclusive sensation in the job market now is the great demand for machine learning engineers which is day after day growing incredibly with the annual growth of 40%. That is why the value and need for machine learning are rising rapidly.

Prerequisites And Skill Needed To Be A Machine Learning Engineer

Machine learning has a few subsets which offer a potential area of expectation for those who are interested in a career in AI. Those are:-

  • Neural networks are essential for computers to teach them how to think and learn by classifying information, similar to what we humans do. The software can recognize images and predict with a great` level of accuracy.
  • Natural Language Processing (NLP) This provides the ability to understand human language to the machines. It makes it easier for us to interact with machines as it develops the machine to respond in a way human audiences can understand.
  • Deep learning This focuses on machine learning tools and places them to solve problems by making decisions. It can be applied to text, images, and speech to come at a conclusion that mimics human decision making.
To become a Machine Learning Engineer, there is no single step. To get a chance to grab this job, you need to take several steps to understand this subject better.
