A Story to Start: From “Do Math” to “Build a Machine”
Imagine you’re teaching a robot to recognize cats. You don’t write rules like “if pointy ears then cat.” Instead, you build a machine that learns rules from data. Under the hood, that machine is a stack of layers wired into a computational graph. TensorFlow is the toolkit that builds the graph, runs it efficiently on CPUs/GPUs/TPUs, and optimizes the machine using gradients.
TensorFlow = Tensors (multi-dimensional arrays) + Flow (they flow through operations) + Autodiff (automatic differentiation) + Execution engines (graph runtime).
