Linnainmaa
A Finnish computer scientist who in 1970 first proposed the reverse-mode automatic differentiation method, providing the mathematical basis for the backpropagation algorithm.
Timeline (last 90 days)
Early work on reverse-mode automatic differentiation can be traced back to Linnainmaa (1970), and Paul Werbos applied it to multilayer networks in 1982.
The concept of backpropagation was not first proposed by Rumelhart et al.; Linnainmaa and others had arrived at similar derivations earlier.
