[Verse 1] Picture neurons firing fast inside your brain Each connection passing signals through the chain Now we'll build machines that copy nature's way Artificial networks learning day by day Input layer catches data streaming in Hidden layers find the patterns locked within [Chorus] Weights and bias, forward pass Backpropagation makes it last Activation functions gate the flow Neural networks learn and grow Training data feeds the mind Complex patterns we will find [Verse 2] Start with simple perceptrons, single layer nodes Add more depth and watch how recognition explodes Sigmoid curves and ReLU functions shape the score Gradient descent adjusts the weights we store Epochs cycle through the dataset once again Teaching machines like we teach our fellow men [Chorus] Weights and bias, forward pass Backpropagation makes it last Activation functions gate the flow Neural networks learn and grow Training data feeds the mind Complex patterns we will find [Bridge] Overfitting traps await the careless mind When models memorize but leave true insight behind Validation sets will test what networks really know Regularization keeps the learning smooth and slow [Verse 3] Image recognition spots the cat from dog Speech to text transcribes our verbal dialogue Financial markets hide their secrets in the noise Neural networks give analysts better choice From biology to silicon the patterns stay the same Teaching silicon to play intelligence's game [Chorus] Weights and bias, forward pass Backpropagation makes it last Activation functions gate the flow Neural networks learn and grow Training data feeds the mind Complex patterns we will find [Outro] Layers deep and connections wide Artificial neurons side by side Learning rules that nature wrote In silicon we strike the note
