2. Understand the Basics of Machine Learning

Once you have the math and programming skills in place, it’s time to explore the core concepts of machine learning. This involves learning how to build algorithms that allow computers to “learn” from data.

Key Concepts to Learn:

• Supervised Learning: The most common form of machine learning, where algorithms are trained on labeled data. Learn about models like linear regression, decision trees, and support vector machines (SVM).
• Unsupervised Learning: Focuses on discovering patterns in data without pre-labeled outcomes. Algorithms like K-means clustering and PCA are key.
• Reinforcement Learning: A type of learning where an agent learns by interacting with an environment and maximizing cumulative rewards.

Beginner-Friendly Courses:

• Andrew Ng’s Machine Learning Course (Coursera): Widely considered the best introductory course for machine learning. It covers the basics and walks you through key algorithms.

Project Ideas:

• Spam Classifier: Build a machine learning model that classifies emails as spam or not spam using NLP techniques.
• Image Classifier: Use a convolutional neural network (CNN) to classify images from a dataset like CIFAR-10 or MNIST.
• Recommendation System: Build a recommendation engine that suggests products or movies based on user behavior.

Pro Tip: Document your projects on GitHub and write about your approach in a blog or portfolio. Sharing your work can help you get noticed by potential employers.

5. Dive into Advanced Topics and Tools

Once you’re comfortable with the basics and have completed some projects, it’s time to explore advanced topics and dive deeper into specific tools and frameworks.

Advanced Areas to Explore:
