Label-Retrieval-Augmented Diffusion Models for Learning from Noisy Labels

Neural Information Processing Systems

However, these methods typically rely on strict assumptions and are limited to certain types of label noise. In this paper, we reformulate the label-noise problem from a generative-model perspective, i.e., labels are generated by gradually refining an initial random guess.

There are several key limitations of the MADE algorithm: 1. As mentioned in Section 3.1, the MADE algorithm can only mask neural networks such that they respect the autoregressive property. The non-deterministic MADE masking algorithm presented in Germain et al. [2015], the resulting Proposition 1 formalizes this point. In Section 3.1, we showed that finding the weight masks for each neural network layer is equivalent Figure 7 provides a visual example of the steps performed by Algorithm 1. 's last row, we need the products of the last row of Randomly generated adjacency structures of 15 dimensions. IP gives better objective values when the adjacency matrix is very sparse.
