Dual T: Reducing Estimation Error for Transition Matrix in Label-noise Learningcs.LG

Dual-T method improves transition matrix estimation in noisy label learning.

problem Large estimation error in noisy class posterior leads to poor transition matrix estimation.

method Introducing an intermediate class to avoid direct estimation of noisy class posterior, factorizing the transition matrix into two easier-to-estimate matrices.

result The dual-T estimator leads to better classification performances.
