Jeff Heaton's 112-page Introduction to the Math of Neural Networks is available as a complete free download (DRM-free PDF), alongside paid Kindle/paperback editions.

It covers the math behind neural network training: matrix mathematics, gradient descent, first/second derivatives, Hessian matrices, backpropagation, resilient propagation, Levenberg–Marquardt optimization, feedforward networks, and self-organizing maps.

The book page also includes errata (e.g., corrected error values in section 2.3.2) and supplementary derivations like the Sigmoid derivative.
