What is ML?
Before diving into the technical definition of machine learning (ML), let's understand what it means in a broader context.
Imagine you are trying to understand your expenditure and decide to categorize your groceries. You start by considering anything above 10 USD as costly and the rest as not. You write a simple program to do this task. It’s straightforward, just an if-else code.
However, you soon realize this method is flawed. Each item is different. For example, Item A costs 12 USD but lasts for two weeks, while Item B costs only 8 USD but lasts only two days because you use it more frequently.
Your next step is to incorporate another factor—usage. Now, your simple if-else block becomes a bit more complex. But, what if you also include some more factors like, which item is easily available, which item is nearer to your home, the number of factors increase a lot and phew, we can stop counting our code blocks!
This is where machine learning (ML) comes into play. Instead of writing countless if-else statements for every possible scenario, ML algorithms allow the computer to learn from data and make decisions based on patterns it detects.
So, what is machine learning? At its core, ML is a method of data analysis that automates analytical model building. It’s a branch of artificial intelligence based on the idea that systems can learn from data, identify patterns, and make decisions with minimal human intervention.

Let’s go back to our grocery example. Imagine you have a large dataset of all your past purchases, including cost, usage, availability, and proximity. Instead of manually coding rules, you feed this data into a machine learning algorithm. The algorithm analyzes the data, learns the patterns, and creates a model. This model can then predict whether a new item is costly based on multiple factors simultaneously.
The importance of machine learning in today’s technology landscape cannot be overstated. It powers personalized recommendations on streaming services, enables autonomous vehicles, enhances medical diagnoses, and optimizes business operations. As we generate more data than ever before, the role of machine learning in extracting valuable insights and automating complex processes continues to grow, making it a pivotal technology in the digital age.
In essence, machine learning shifts the paradigm from explicitly programming computers on what to do, to training them to make decisions based on data. This approach not only simplifies complex tasks but also opens up a world of possibilities that were previously unattainable with traditional programming methods.
Thank you for reading up to this point. This is just the beginning of our journey into the fascinating world of machine learning. We'll dive deeper into various algorithms, explore real-world use cases, and walk through practical examples.
