_BaseSolver

class _BaseSolver

Base class for solvers for the Operator Inference regression problem. Child classes should receive and store hyperparameters in the constructor (regularization scalars, truncation size, etc.).

Properties

A	Left-hand side data matrix.
B	"Right-hand side matrix B = [ b_1 | .
d	Number of unknowns to learn in each problem (number of columns of A).
k	Number of equations in the least-squares problem (number of rows of A).
r	Number of independent least-squares problems (number of columns of B).

Methods

cond	Calculate the 2-norm condition number of the data matrix A.
fit	Verify dimensions and save A and B.
misfit	Calculate the data misfit (residual) of the non-regularized problem for each column of B = [ b_1 | .
predict	Solver the learning problem.
