Label smoothing improves model performance even with noisy labels.
We describe a nonparametric topic model for labeled data. The model uses a mixture of random measures (MRM) as a base distribution of the Dirichlet process (DP) of the HDP framework, so we call it the DP-MRM. To model labeled data, we define a DP distributed random measure for each label, and the resulting model genera…

Retraining with predicted labels improves model accuracy in noisy settings.
Machine learning approaches to multi-label document classification have to date largely relied on discriminative modeling techniques such as support vector machines.

Conditional Random Fields (CRF) are frequently applied for labeling and segmenting sequence data. Morency et al.

Such a model is known as Latent-Dynamic…

Multi-label classification (MLC) is the task of assigning a set of target labels for a given sample. Modeling the combinatorial label interactions in MLC has been a long-haul challenge. We propose Label Message Passing (LaMP) Neural Networks to efficiently model the joint prediction of multiple labels. LaMP treats labe…
It is challenging to handle a large volume of labels in multi-label learning.

Because large, human-annotated datasets suffer from labeling errors, it is crucial to be able to train deep neural networks in the presence of label noise. While training image classification models with label noise have received much attention, training text classification models have not. In this paper, we propose an…
