Unfortunately, while this sped up reverse AD for our SFM kernel by 300%, reverseAD was only 6%, and is now 2% of total time. So, time to look elsewhere. Oh, and, it is clear that the Identity matrix for Leaf only expressions is completely known at compile time: Eigen::Matrix::Identity().

Unfortunately, the jet +// framework is designed for a single-parameter vector-valued input. The wrapper +// in this file addresses this issue adding support for functions with one or +// more parameter vectors. +// +// To support multiple parameters, all the parameter vectors are concatenated +// into one and treated as a single parameter vector, except that since the +// functor expects different inputs, we need to construct the jets as if they +// were part of a single parameter vector. The extended jets are passed +// separately for each parameter. +// +// For example, consider a functor F taking two vector parameters, p[2] and +// q[3], and producing an output y[4]: +// +// struct F { +// template +// bool operator()(const T *p, const T *q, T *z) { +// // ... +// } +// }; +// +// In this case, the necessary jet type is Jet.

Dual +// numbers are extensions of the real numbers analogous to complex numbers: +// whereas complex numbers augment the reals by introducing an imaginary unit i +// such that i^2 = -1, dual numbers introduce an "infinitesimal" unit e such +// that e^2 = 0. Dual numbers have two components: the "real" component and the +// "infinitesimal" component, generally written as x + y*e. Surprisingly, this +// leads to a convenient method for computing exact derivatives without needing +// to manipulate complicated symbolic expressions. +// +// For example, consider the function +// +// f(x) = x^2 , +// +// evaluated at 10. Using normal arithmetic, f(10) = 100, and df/dx(10) = 20. +// Next, augument 10 with an infinitesimal to get: +// +// f(10 + e) = (10 + e)^2 +// = 100 + 2 * 10 * e + e^2 +// = 100 + 20 * e -+- +// -- | +// | +--- This is zero, since e^2 = 0 +// | +// +----------------- This is df/dx! +// +// Note that the derivative of f with respect to x is simply the infinitesimal +// component of the value of f(x + e). So, in order to take the derivative of +// any function, it is only necessary to replace the numeric "object" used in +// the function with one extended with infinitesimals. The class Jet, defined in +// this header, is one such example of this, where substitution is done with +// templates. +// +// To handle derivatives of functions taking multiple arguments, different +// infinitesimals are used, one for each variable to take the derivative of. For +// example, consider a scalar function of two scalar parameters x and y: +// +// f(x, y) = x^2 + x * y +// +// Following the technique above, to compute the derivatives df/dx and df/dy for +// f(1, 3) involves doing two evaluations of f, the first time replacing x with +// x + e, the second time replacing y with y + e. +// +// For df/dx: +// +// f(1 + e, y) = (1 + e)^2 + (1 + e) * 3 +// = 1 + 2 * e + 3 + 3 * e +// = 4 + 5 * e +// +// --> df/dx = 5 +// +// For df/dy: +// +// f(1, 3 + e) = 1^2 + 1 * (3 + e) +// = 1 + 3 + e +// = 4 + e +// +// --> df/dy = 1 +// +// To take the gradient of f with the implementation of dual numbers ("jets") in +// this file, it is necessary to create a single jet type which has components +// for the derivative in x and y, and passing them to a templated version of f: +// +// template +// T f(const T &x, const T &y) { +// return x * x + x * y; +// } +// +// // The "2" means there should be 2 dual number components. +// Jet x(0); // Pick the 0th dual number for x. +// Jet y(1); // Pick the 1st dual number for y. +// Jet z = f(x, y); +// +// LOG(INFO) << "df/dx = " << z.a[0] +// << "df/dy = " << z.a[1]; +// +// Most users should not use Jet objects directly; a wrapper around Jet objects, +// which makes computing the derivative, gradient, or jacobian of templated +// functors simple, is in autodiff.h. Even autodiff.h should not be used +// directly; instead autodiff_cost_function.h is typically the file of interest. +// +// For the more mathematically inclined, this file implements first-order +// "jets". A 1st order jet is an element of the ring +// +// T[N] = T[t_1, ..., t_N] / (t_1, ..., t_N)^2 +// +// which essentially means that each jet consists of a "scalar" value 'a' from T +// and a 1st order perturbation vector 'v' of length N: +// +// x = a + \sum_i v[i] t_i +// +// A shorthand is to write an element as x = a + u, where u is the pertubation. +// Then, the main point about the arithmetic of jets is that the product of +// perturbations is zero: +// +// (a + u) * (b + v) = ab + av + bu + uv +// = ab + (av + bu) + 0 +// +// which is what operator* implements below. Addition is simpler: +// +// (a + u) + (b + v) = (a + b) + (u + v). +// +// The only remaining question is how to evaluate the function of a jet, for +// which we use the chain rule: +// +// f(a + u) = f(a) + f'(a) u +// +// where f'(a) is the (scalar) derivative of f at a. +// +// By pushing these things through sufficiently and suitably templated +// functions, we can do automatic differentiation.
