Machine Learning (ML) is a field that has become very popular in today’s time, and its applications are seen in every industry. If you also want to make a career in this field, then this blog post is perfect for you. I, Ashish Bula, an AI and Machine Learning Consultant, will explain to you from fundamentals to advanced concepts of machine learning. You will get a chance to understand each concept step-by-step, and you will be able to apply your learning through practical projects.
What is Machine Learning?
Machine learning (ML) is a subfield of AI (artificial intelligence) that gives computer systems the ability to learn from data without being explicitly programmed. This means that you can improve the machine, without human intervention, whenever new data is available.
You might be wondering how this is possible, so let me explain with an example.
Example: Suppose a machine has to create your email filtering system. You train the machine by giving it initial data, in which you will get data of spam and non-spam emails. As the data increases, the machine will learn to classify emails on its own.
Why learn machine learning?
The demand for machine learning skills is growing every day, and its applications are across every industry. If you have an interest in data-driven decision making, or you have a passion for problem-solving and innovative solutions, machine learning could be the perfect field.
Personal experience: When I was initially learning ML, I thought it was very difficult. But when I understood the basic algorithms like linear regression and decision trees, everything started to seem simple. Today I am teaching these skills to other people through my machine learning projects and courses.
How to start learning Machine Learning?
If you want to start machine learning, here are some basic steps you should follow:
- Learn the basics of math:
- You will understand the concepts of linear algebra, calculus, and probability, which are essential for understanding ML algorithms.
- Choose a programming language:
- Python is most commonly used in machine learning because it has data science and machine learning libraries like NumPy, Pandas, and Scikit-learn available.
- Understand the types of machine learning:
- Supervised learning: When you train data with labels (like regression, classification).
- Unsupervised learning: When you train data without labels (like clustering).
- Reinforcement learning: When you make the machine learn through rewards and punishments.
Personal recommendation: When I was learning machine learning, I used Python and used the scikit-learn library through a lot of practical experiments. I recommend you to try these libraries too.
4. Get practical experience:
- You need to practice along with theory. On Kaggle, you get real-world datasets where you can test your skills.
5. Create a project:
- The real test of your learning comes when you create your own project. Machine learning projects, such as predictive models or recommendation systems, can help you polish your skills.

Common mistakes to avoid in machine learning
- Ignoring data quality: Data cleaning is one of the most important steps. Make sure the data you are using is clean and relevant.
- Overfitting model: If your model is performing very well on its training data, but not on the testing data, then you are overfitting.
- Not understanding the algorithm: Just writing the code is not enough, you also need to understand the theory of the algorithm.
