Bayesian SVMs would resolve the uncalibrated probability limitation that restricts SVM deployment — by reinterpreting SVMs as graphical models with automatic hyperparameter tuning and native uncertainty quantification, the Bayesian formulation addresses the calibration gap without sacrificing SVMs' convex optimization guarantees and global optimality properties.

Justifications

SL — Bayesian interpretation resolves SVM calibration only if scaling complexity doesn't overwhelm the approach

Antecedents (all must be IN):

IN svm-bayesian-auto-hyperparameter-uncertainty — Bayesian SVM (Polson & Scott, 2011) interprets the SVM as a graphical model, enabling automatic hyperparameter tuning and predictive uncertainty quantification, unlike standard SVMs that require cross-validation.
IN svm-limitations-labeled-data-binary-uncalibrated — Key SVM limitations: requires fully labeled data, produces uncalibrated probabilities, is natively binary-only (multiclass requires reduction strategies), and has difficult-to-interpret parameters.

Unless (any of these IN defeats this justification):

IN svm-complexity-compounds-with-scale — SVM complexity compounds as problems scale — multiclass classification requires architectural decomposition (OvA/OvO/Crammer-Singer) on top of already scale-dependent solver selection (SMO vs Pegasos vs LIBLINEAR), creating a combinatorial methodology burden that contrasts with neural network approaches which handle multiclass classification more naturally.
