WebNext, we must define our model, relating its input and parameters to its output. Using the same notation in , for our linear model we simply take the matrix-vector product of the input features \(\mathbf{X}\) and the model weights \(\mathbf{w}\), and add the offset \(b\) to each example. \(\mathbf{Xw}\) is a vector and \(b\) is a scalar.
