LeCun's own retrospective describes his 1985 algorithm as propagating "virtual target values," not gradients, with no control-theory framing

claim seedling Tier 1 2026-10-16 · yann-lecun, paul-werbos, arthur-bryson, backpropagation, priority-vs-paternity
LeCun's own account dates the rigorous, Lagrangian (duality-adjacent) derivation of backpropagation to his 1988 paper, not the 1985 Cognitiva paper

claim seedling Tier 1 2026-10-16 · yann-lecun, paul-werbos, arthur-bryson, backpropagation, priority-vs-paternity
Does LeCun's 1985 paper actually derive backpropagation via 'duality theory from control theory (Bryson and Ho, 1969)', as Werbos's 2004 patent characterizes it?

capture promoted 2026-10-15 · paul-werbos, yann-lecun, arthur-bryson, backpropagation, priority-vs-paternity
Werbos's 2004 'Object Nets' patent names LeCun twice in its body text, contrasting a 1985 'duality theory' derivation with Werbos's own 1974 one

Werbos's 2006 AD2004 retrospective, read in full, never names LeCun

Does LeCun's 1985 paper actually derive backpropagation via 'duality theory from control theory (Bryson and Ho, 1969)', as Werbos's 2004 patent characterizes it?

question open 2026-10-14 · paul-werbos, yann-lecun, arthur-bryson, backpropagation, priority-vs-paternity
Does Werbos's 1994 'Roots of Backpropagation' book, or the 2006 retrospective Schmidhuber cites as 'Werbos, 1981, 2006', ever mention LeCun by name?

capture promoted 2026-10-12 · paul-werbos, yann-lecun, backpropagation, history-of-ml, embedding-bridge-check
No literature source connects LeCun's 1989 'first practical recognition' claim to Werbos's 1988 Deutsch-project 'first actual application' claim — an analytical contrast, not an evidentiary bridge

question open 2026-10-11 · paul-werbos, yann-lecun, backpropagation, history-of-ml, embedding-bridge-check
Does any source connect LeCun's 1989 'first practical recognition application' to Werbos's 1988 Deutsch-project 'first actual application' claim?
