GANs recapitulate at the individual model level the field-wide pattern where pragmatic shortcuts drive both capability and crisis — their implicit generative approach (pragmatically avoiding intractable likelihood computation) simultaneously enabled unique capabilities (single-pass generation, cross-domain applications) and created fundamental training instability, making GANs the clearest single-model exemplar of the pragmatism-crisis dynamic.
Justifications
SL — GANs' implicit-vs-explicit design choice is a microcosm of ML's field-wide pragmatism paradox
Antecedents (all must be IN):
- IN gan-implicit-nature-explains-training-difficulty — GANs' implicit generative nature (no explicit likelihood function) is plausibly connected to their need for multiple complementary training interventions — without a tractable objective to optimize directly, training stability relies on several distinct design choices (non-saturating loss, TTUR, deterministic discriminators) each addressing a different failure mode, which may partly substitute for the more direct optimization signal that explicit-likelihood models enjoy.
- IN pragmatism-drives-both-capability-and-crisis — ML's pragmatic character is a primary driver of both its capability achievements and its reliability challenges — pragmatic shortcuts over formal prerequisites contribute to capability advances (backprop succeeds despite violated assumptions) while the same pragmatism introduces systematic fragility (adversarial vulnerability), making capability and crisis closely linked consequences of this evolutionary strategy.
Dependents
These beliefs depend on this one:
- IN gan-nash-impossibility-mathematically-necessitates-model-level-crisis — Farnia & Ozdaglar's proof that GANs lack guaranteed Nash equilibria provides formal grounding for the GAN-level pragmatism-crisis dynamic — the training instability that exemplifies the field-wide crisis pattern at the model level is not merely an empirical tendency but has a provable theoretical basis in adversarial game structure, strengthening the case that the pragmatism-crisis pattern at the model level is structurally rooted rather than incidental.
- IN pragmatism-crisis-scale-invariant — ML's pragmatism-crisis dynamic is scale-invariant — it operates identically at the individual model level (GANs recapitulate field-wide patterns where pragmatic shortcuts drive both capability and crisis) and at the paradigm level (generative model succession from GANs to diffusion models exemplifies the same innovation-then-displacement cycle), suggesting the tension between pragmatic capability and theoretical fragility is a structural property of pragmatic systems rather than a contingent feature of any particular scale.
- OUT scale-invariance-enables-model-level-intervention — The fractal nature of ML's crisis — identical pragmatism-crisis dynamics at model, paradigm, and field levels — would enable targeted model-level intervention as a template scalable to the field level, since resolving the dynamic at the most tractable scale (individual model training, e.g. GAN stabilization) would demonstrate a pattern replicable upward through paradigm and field levels.
- IN selection-pressure-determines-reliability-over-mathematics — GANs and SVMs illustrate contrasting outcomes of different selection pressures in ML — SVMs, shaped by intellectual selection pressure, achieved strong theory-practice unity and methodological reliability, while GANs, shaped by pragmatic selection, gained unique capabilities but inherited fundamental training instability. This contrast suggests that the type of selection pressure is a primary factor in determining methodological reliability, though both cases involve sophisticated mathematics, indicating that mathematical rigor alone is insufficient without the selection environment that prioritizes it.
