Building Artificial Neurons: Foundations of Neural Networks

Understanding how the human brain inspires artificial intelligence is the first step to mastering modern machine learning. This text-based course guides you from the biological foundations of a neuron to building your first functional artificial neuron model from scratch. What you will learn: Learn the biological concepts behind neural pathways and how they translate to computational nodes; Understand how weights, biases, and inputs combine mathematically to process information; Implement essential activation functions, including classical step functions and modern standards like ReLU; Build a single-layer perceptron in Python using clean coding practices and type hints; Practice calculating weighted sums and forward propagation steps through structured written exercises. You will begin with fundamental terminology and biological analogies before moving on to mathematical representations and hands-on Python code implementations. Designed for absolute beginners curious about AI foundations, this course requires no prior background in advanced mathematics or machine learning.
