Whenever there’s a mention of machine learning (ML) or artificial intelligence (AI), most people want to know: Is machine learning hard to learn? On the surface, it’s understandable why many people believe it to be a complicated subject to master.
For one, there’s math involved. Secondly, you need to have extensive programming knowledge and be familiar with algorithms and distributed computing. Thirdly, experimentation is a crucial aspect of machine learning, and it requires a lot of time and effort to excel.
While it’s true that you need to know some basic math—including probability, statistics, and linear algebra—have programming knowledge, and be comfortable working with algorithms, it’s not as challenging as you probably think to get into machine learning.
There are plenty of resources out there that can teach you the basics of machine learning, including books, online courses, and even tutorials on specific algorithms.
Once you have a basic understanding of machine learning, you can apply it to real-world problems.
In this guide, we’ll answer your burning question: How hard is machine learning? Plus, we’ll share some helpful resources to get started.
What Is Machine Learning?
Machine learning refers to teaching a computer to think and act like a human brain without human intervention. It’s a data analysis method that automates the process of analytical model building. Machine learning is a branch of AI that works on the principle that machine systems learn from data and make decisions based on the patterns they’ve picked up.
For instance, image and speech recognition are notable use cases of machine learning in today’s world.
Let’s say you want a software to identify objects in images. The first thing you would do is give it a lot of training data, which in this case would be a bunch of images with the objects you want it to identify already labeled. Then, you would use a machine-learning algorithm to teach the AI how to identify those objects.
After the AI has been trained, you can then give it new images, and it will be able to identify the objects in them.
What Makes Machine Learning Hard To Learn?
Is machine learning hard? Yes, it is. But what makes it so hard to learn? Here are some factors that can sometimes prove challenging when you’re getting started with machine learning.
- Extensive programming knowledge. To implement machine learning algorithms, you need to have a strong understanding of programming languages like Python, Julia, and other advanced programming languages.
- Deep learning. Deep learning is a branch of machine learning that uses a deep neural network to develop algorithms capable of achieving human-level performance on complex tasks. To learn deep learning, you’ll need a solid understanding of math and statistics in addition to your programming skills.
- Distributed computing. Machine learning algorithms typically scale when they’re distributed across a large number of computers during the training process. If you want to venture into distributed computing, you will need a certain amount of knowledge in software engineering and cloud computing.
- Difficult algorithms: Machine learning algorithms can be difficult to understand, especially for beginners. Each algorithm has different components that you need to learn before you can apply them. Even then, not all algorithms will work well with your data set or business problem, so experimentation is needed to find the right approach.
- Math skills: It would help if you were comfortable with basic math concepts such as probability, statistics, and linear algebra to understand machine learning algorithms. Mastering these concepts can be difficult due to their complexity. You also need to learn how to use each idea in machine learning, which requires you to understand these topics in-depth rather than just the basics.

- Machine learning
- Neural networks
- Expert systems
- Data science
- Logistic regression
- Big data
- Deep learning algorithms
- Speech processing
- Natural language processing
- Evolutionary computation
- Computer vision
Most machine learning models are built in six steps. These are data collection and access, data exploration and preparation, model building, model evaluation, model deployment, and model monitoring.
You should be familiar with these steps because they will help you throughout your machine learning journey.
To better understand machine learning algorithms, you need to learn the basics of linear algebra, linear regression, speech recognition, statistics, and probability. You should know how these mathematical concepts are implemented in modern-day computer science problems such as clustering and support vector machines (SVMs).
Knowing these concepts is beneficial because it will help you with regression and classification.
Utilize Free Resources
Fortunately, many free resources for machine learning are available online. You can find several books and introductory YouTube tutorials, lectures, blogs, etc. on various websites. For instance, Paradigms of Artificial Intelligence Programming is a free book you can read to familiarize yourself with the fundamentals of machine learning.
Google also offers a Machine Learning Crash Course that provides an interactive visualization of algorithms in action.
In addition, there are also free software tools that you can use for data exploration, pre-processing, and modeling.
