Expand description
Post-hoc error estimation for tensor train approximations.
After running crossinterpolate2,
estimate_true_error can verify the approximation quality by
searching for multi-indices with large interpolation error via
floating_zone optimization.
Functionsยง
- estimate_
true_ error - Estimate the true interpolation error by searching for worst-case indices.
- floating_
zone - Local search for the multi-index with the largest interpolation error.
