Foundations of Neural Networks and Deep Learning

Neural networks are the driving force behind modern artificial intelligence, yet their inner workings can often seem like a black box. Understanding the core mathematical and structural concepts is the first step toward building and tuning your own deep learning models. This text-only course guides you through the foundational principles of neural networks from the ground up. You will learn how data flows through a network, how weights are updated, and how to implement basic architectures using modern programming practices. What you'll learn: Understand the fundamental architecture of neural networks, including layers, weights, biases, and modern activation functions like ReLU. Apply the mathematics of forward propagation and backpropagation to see how networks learn from data. Configure optimization algorithms like gradient descent to minimize errors and improve model performance. Evaluate model performance using essential metrics to ensure accuracy and avoid overfitting. Practice implementing basic neural network concepts using clean, modern Python code structures. You will begin with essential terminology and the basic anatomy of a single neuron before progressing to multi-layer networks. Through clear written explanations and step-by-step code walkthroughs, you will explore how optimization algorithms train these networks to make predictions. This course is designed for aspiring data scientists, software developers, and curious beginners who want a clear, conceptual introduction to deep learning without needing prior experience in advanced artificial intelligence.
