SVMs and GANs illustrate contrasting degrees of methodology codification in ML — SVMs have an unusually prescriptive practical recipe (standardize, default to RBF, grid-search C and gamma), while GAN training stability requires multiple complementary but individually insufficient interventions (non-saturating loss, two-timescale updates, deterministic discriminators) addressing distinct failure modes, suggesting that well-understood convex optimization enables more codified practice than implicit generative modeling with competing failure modes.
Justifications
SL — SVM prescriptive methodology vs GAN ad-hoc interventions reveals theoretical completeness as prerequisite for codified practice
Antecedents (all must be IN):
- IN svm-codified-practical-methodology — SVMs have an unusually prescriptive practical methodology for ML: standardize features first, default to RBF kernel, then grid-search C and gamma with cross-validation.
- IN gan-training-stability-requires-multiple-interventions — GAN training stability benefits from several complementary design choices — non-saturating loss to address vanishing gradients when the generator is poor, two-timescale update rule for provable convergence to a stationary local Nash equilibrium (though not mode collapse prevention), and deterministic discriminators for optimality of the discriminator — each addressing a distinct failure mode, but none individually sufficient for overall stability.
Dependents
These beliefs depend on this one:
- IN svm-methodology-codification-mirrors-optimization-topology — The contrast between SVMs' prescriptive methodology (standardize, RBF default, grid-search) and GANs' ad-hoc training recipes appears to be significantly influenced by their optimization topologies — convexity enables more codifiable methodology while non-convex minimax games resist systematization, suggesting that optimization landscape is an important factor in methodology maturity, though the evidence from these two cases alone is insufficient to establish it as the sole or root determinant.
