How to learn Machine Learning from scratch

Machine learning might sound like rocket science, but trust me, it’s not! It’s like teaching your computer to be smart. If you’re curious and ready to learn, here’s how to dive into the world of machine learning from scratch, no rocket required.

Step 1: Get Friendly with Python

Think of Python as your new best friend in this journey. It’s a programming language that’s super friendly for beginners. You’ll need it to write code for your machine learning adventures. Install Python on your computer, and you’re all set.

Step 2: Math Is Your Superpower

No, you don’t have to be an expert in mathematics, although learning the fundamentals will help. Division, multiplication, and addition should be practiced first. Mathematical analysis, calculus, and statistics should follow. For arithmetic lessons, you should turn to Khan Academy and YouTube.

Step 3: Get to Know Your Data

Machine learning is all about data. Think of data as ingredients for a recipe. You need to understand what’s in your data before you can cook up a great machine learning model. Learn to clean, organize, and explore data using libraries like Pandas in Python.

Step 4: The Machine Learning ABCs

Okay, now the fun really starts. A computer can learn to spot patterns through machine learning. 

Supervised Learning: It’s like teaching your computer with labeled examples. For instance, showing it pictures of cats and dogs and telling it which is which.

Unsupervised Learning: Here, your computer figures things out on its own. Think of it as finding hidden patterns in data, like clustering similar things together.

Deep Learning: This is like the superhero of machine learning. It’s all about neural networks, which can do amazing things like recognizing faces or playing chess.

Step 5: Pick Your Model

There are many machine learning models out there. Start with the simple ones like Linear Regression or Decision Trees. As you get comfortable, you can dive into fancier ones like Random Forests and Neural Networks. Scikit-Learn is a fantastic Python library to get you started.

Step 6: Online Courses Are Your BFFs

You don’t have to return to school. There are many economical and free online learning opportunities.

Coursera’s “Machine Learning” by Andrew Ng: It’s like having a private tutor.

edX’s “Introduction to Artificial Intelligence:” Offers a gentle introduction to the world of AI and machine learning from scratch.

Fast.ai’s “Practical Deep Learning for Coders:” Dive into deep learning without drowning in jargon.

Step 7: Continue practicing.

The key is to actively learn new skills. Begin with something simple, like estimating a house’s price based on its size.  As you gain confidence, tackle more complex projects. Websites like Kaggle have tons of real-world datasets and challenges to sink your teeth into.

Step 8: Show Off Your Skills

Set up a GitHub account and showcase your projects. It’s like your online resume for tech folks. Plus, it’s a great way to get feedback and collaborate with others.

Step 9: Join the ML Community

This journey includes other people. Join discussion boards like #Machine Learning on Twitter, Stack Overflow, or r/Machine Learning on Reddit to communicate with other students. If you can, go to conferences or meetings; it’s always a plus to meet people in person.

Step 10: Patience is a Virtue

Recall that neither Rome nor professionals in machine learning were created overnight. Making errors is acceptable since it helps you learn. Don’t give up hence when times are difficult. Keep exploring, learning, and having fun along the way.

So there you have it! 

Learning machine learning from scratch doesn’t require a PhD or fancy jargon. It’s about curiosity, determination, and a willingness to explore. Grab your Python buddy, dive into the data, and let the machine learning adventure begin! Happy coding! 🚀
