[Verse 1] Deep inside the circuits, there's a pattern we can see Neurons fire together, like synapses you and me Each connection holds a weight, a number small or large When the signals flow together, they decide what's in charge [Chorus] Neural networks learn and grow Input, hidden, output flow CNNs see the world so clear RNNs remember what they hear Transformers pay attention now Building blocks of AI, we'll show you how [Verse 2] Start with simple perceptrons, they make a yes or no Add more layers in between, watch the magic start to grow Forward pass sends data through, from left side to the right Backpropagation learns from wrong, adjusting weights each night [Chorus] Neural networks learn and grow Input, hidden, output flow CNNs see the world so clear RNNs remember what they hear Transformers pay attention now Building blocks of AI, we'll show you how [Bridge] Convolutional layers scan for edges, shapes, and lines Pooling layers shrink it down, finding patterns in the signs Recurrent networks hold the past, in memory they keep Long short-term can bridge the gap when sequences run deep [Verse 3] Attention is the newest trick, it weights what matters most Transformers changed the game complete, from coast to coast they boast Self-attention looks within, cross-attention looks between Multi-headed parallel processing, smartest we've ever seen [Chorus] Neural networks learn and grow Input, hidden, output flow CNNs see the world so clear RNNs remember what they hear Transformers pay attention now Building blocks of AI, we'll show you how [Outro] From image recognition bright To language models day and night These building blocks will pave the way For AI systems every day
