Robust Classification with Noisy Labels Based on Posterior Maximization

  • This paper investigates the robustness of an f-divergence-based class of objective functions, referred to as f-PML, to label noise in supervised classification.
  • The study shows that, in the presence of label noise, the f-PML objective functions can be corrected to obtain a neural network that matches the clean dataset.
  • An alternative correction approach is proposed to refine the posterior estimation during the test phase for neural networks trained with label noise.
  • The paper demonstrates that the f-PML objective functions are robust to symmetric label noise and can achieve competitive performance with refined training strategies.
