Truncation Method for TSVD with Account of Truncation Bias

Truncation Method for TSVD with Account of Truncation Bias

TSVD truncate small singular values by truncation parameter to improve the parameter estimation of ill-posed model. From the perspective of MSE (mean squared error), TSVD introduce biases to reduce variances, therefore the stability and reliability of the solution can be improved. Truncation paramet...
