Episode 12 — Neural Networks — From Neurons to Layers

Certified - Introduction to AI Audio Course

Artificial neural networks are inspired by the structure of the human brain but simplified into mathematical models that drive today’s most powerful AI systems. In this episode, we begin with the perceptron, an early model of a single artificial neuron, then explore how weights, activation functions, and layers combine to process information. Multi-layer networks, trained through backpropagation and optimized with gradient descent, allow AI to model complex relationships in data. Key concepts like loss functions, epochs, and overfitting are explained in plain language, showing how these abstract ideas shape model performance.

From there, we expand into the diversity of neural architectures. Convolutional networks power vision systems, recurrent and long short-term memory networks handle sequences like speech and text, and transformers represent the latest leap in language processing. Applications span image recognition, speech transcription, translation, and medical imaging. Ethical concerns, interpretability challenges, and computational demands are also discussed, helping listeners understand not only the mechanics but the responsibilities of deploying neural networks. By the end, you’ll see why neural networks are considered the backbone of modern AI.
