Starting to learn machine learning from scratch can be an exciting and rewarding journey. Here's a step-by-step guide to help you get started:

1. Get Comfortable with the Basics

  • Mathematics: Familiarize yourself with essential mathematical concepts:
    • Linear Algebra: Vectors, matrices, and matrix operations.
    • Probability and Statistics: Probability distributions, Bayes' theorem, and statistical tests.
    • Calculus: Derivatives, gradients, and optimization.
  • Programming: Learn Python, the most widely used programming language in machine learning, and get comfortable with coding basics.

2. Understand Machine Learning Concepts

  • Supervised Learning: Learn about algorithms that work with labeled data, such as linear regression, decision trees, and support vector machines.
  • Unsupervised Learning: Study algorithms for working with unlabeled data, like clustering (e.g., K-means) and dimensionality reduction (e.g., PCA).
  • Overfitting and Underfitting: Understand how to balance model complexity to avoid overfitting and underfitting.
  • Evaluation Metrics: Learn about accuracy, precision, recall, F1-score, and other metrics to evaluate model performance.
