omnibias.symbolic

Neural-jet equation discovery and interpretable surrogates. Because every jet column is an exact omnibias fastpath, the discoverers recover identities library-free — without being handed an exp, sin, or tanh basis.

import omnibias.symbolic as os_

This is a large package; the highlights below group the public surface by task.

  • uncertainty: bootstrap_coefficients, ridge_coefficient_covariance, certified_coefficient_intervals, attach_uncertainty.
  • dimensional analysis: buckingham_pi_groups, dimension_matrix, is_dimensionless, n_dimensionless_groups.

Applied & verified reports

solve_blasius / discover_blasius_identity, latent-ODE discovery (discover_latent_ode, takens_embedding), and a large family of verify_* report builders for fluid / regularity / mass-gap proof-preparation candidates.

These are candidates, not closures

The verify_* / candidate-artifact routines build and check finite proof obligations and diagnostic reports. They are proof-preparation; they do not close the infinite analytic obligations of the underlying open problems. See scope boundaries.
