• Combining classifier and cluster ensembles for semi-supervised and transfer learning 

    Acharya, Ayan (2012-05)
    Unsupervised models can provide supplementary soft constraints to help classify new, "target" data since similar instances in the target set are more likely to share the same class label. Such models can also help detect ...
  • Knowledge transfer using latent variable models 

    Acharya, Ayan; 0000-0003-3023-4337 (2015-08)
    In several applications, scarcity of labeled data is a challenging problem that hinders the predictive capabilities of machine learning algorithms. Additionally, the distribution of the data changes over time, rendering ...
