How Long Does It Take to Learn Machine Learning?

Machine learning is a type of artificial intelligence. Using data and algorithms, machine learning allows systems to imitate the way humans learn without specific programming. There’s a wide range of applications including internet search engines, email filters, personal recommendations on websites, and much more! We’ve only just scratched the surface of what machine learning can accomplish, but it’s already an important part of companies like Google and Facebook. Machine learning engineers are in high demand, so how long does it take to learn the skills necessary to succeed in this field?

If you’re starting from scratch, it can take a few years to develop a strong data science foundation. For those with established backgrounds in data or computer science, you can reach intermediate machine learning skills in under a year. With another 6+ months of practice, you can become a machine learning expert.

What is machine learning?

As we mentioned, machine learning is a type of artificial intelligence. The goal is for computers to learn on their own without human involvement. You start with data or observations. Machine learning is only as good as the data. For the best results, systems need huge amounts of data to work with. Machine learning also trains algorithms to look for patterns and trends, so the systems can give better predictions and insights.

There are three types of learning algorithms: supervised, unsupervised, and reinforcement. With supervised learning, the system gets fed labeled datasets during its training. Labeled test data is then presented to the system, but the algorithm doesn’t know the labels. This tests the accuracy of the algorithm. Supervised algorithms tend to only work well if there are lots of correctly-labeled data and you know what you’re looking for in the data. For unsupervised algorithms, the training data isn’t labeled. The algorithm works freely and can find patterns humans weren’t aware of. It’s best applied when you don’t have data on any desired outcomes, like for recommender systems and targeted marketing campaigns. Reinforcement learning trains models to make a series of decisions in service of a goal. The environment the system works in is uncertain and complex, so the system uses trial-and-error to identify a solution. Reinforcement learning could be applied to self-driving cars, industrial automation, and healthcare.

How long it takes to develop beginner skills in machine learning – building a data science foundation, understanding programming languages, understanding databases

If you already have a background in data science or computer programming, you can start learning machine learning right away. If you don’t, it can take around 6-9 months (with 6-7 hours of work per day) to learn the basics of data science, according to Data Science Nerd. Unless you’re in school for data science, most people don’t have that many hours a day to study, so expect it to take longer. A bachelor’s degree in data science takes the usual four years while a master’s degree (which isn’t always required to be a machine learning professional, but it’s useful) takes two years. Most machine learning engineers have at least a bachelor’s in data or computer science.

Before starting machine learning, you’ll need to build a strong foundation and learn about concepts like programming languages (Python is very popular for machine learning engineers), analytical tools like SAS and R, unstructured data, and SQL databases. With a data science background, you’ll be familiar with the concepts required to start machine learning, like programming, statistics, probability, and other mathematics.

How long it takes to reach intermediate machine learning skills – understanding machine learning fundamentals and becoming more familiar with data types, models, etc

When you come from a data science background, you have a leg up on machine learning and can quickly develop intermediate skills. With consistent practice, leveling up can take as little as six months. You’ll become very familiar with the fundamentals of machine learning, like data types, larger databases, analysis, deep learning, AI, and will learn how to apply them.

There are countless machine learning courses available online that can help you develop intermediate skills. Boot camps are also an option, though bear in mind that they’re intense and require true commitment. Boot camps aim to teach practical skills very quickly, so a person can get a job by the end of the curriculum. The Springboard boot camp, which the blog describes, takes 6 months with 15-20 hours of study per week. During the camp, participants learn to clean and transform data, design a machine learning/deep learning system, and deploy a running application.

How long it takes to develop advanced machine learning skills – creating software and models, managing large databases, and working with deep learning, AI, and algorithms

Once you have a solid base in data science and intermediate machine learning, it can take less than a year to become an expert. In a Quora answer on how long it takes to become a machine learning expert, Sairam Uppugundla (Founder and CEO, Codegnan IT Solutions OPC Pvt Ltd) suggested about six months. It depends on how many hours you can practice each day. At the advanced level, machine learning engineers know how to develop and improve software, create automation tools and learning models, and manage large databases and big data tools. They also have lots of project experience and a deep understanding of how AI and algorithms work.

We can also get a clearer idea of what’s considered “advanced” by looking at courses on advanced machine learning. Coursera hosts an advanced machine learning and signal processing course from IBM where students use a real-life example from IoT, learn the fundamentals of Linear Algebra, and work on a self-created dataset. The course is part of a 4-month advanced data science specialization but takes about 28 hours on its own.

Why should you learn machine learning?

Machine learning is only getting more and more exciting as the world gets more clarity on its potential. Here are three reasons why you should learn machine learning:
