WebWe will explore two types of automatic differentiation in Julia (and discuss a few packages which implement them). For both, remember the chain rule d y d x = d y d w ⋅ d w d x Forward-mode starts the calculation from the left with d y d w first, which then calculates the product with d w d x.

WebThese types allow the user to easily feed several different parameters to ForwardDiff's API methods, such as chunk size, work buffers, and perturbation seed configurations. ForwardDiff's basic API methods will allocate these types automatically by default, but you can drastically reduce memory usage if you preallocate them yourself.
