I've seen a fair amount of this "\(\mathbf{W}\cdot\mathbf{x}+\mathbf{b}=\mathbf{y}\)" stuff on the web recently, and my eyes glaze over even harder than they do when confronted with traditional math notation. Is this intended to be a human-readable notation, which I could possibly go learn somewhere if I knew what it was called, or is this the result of failed javascript?
