We propose a Multi-Instance-Learning (MIL) approach for weakly-supervised learning problems, where a training set is formed by bags (sets of feature vectors or instances) and only labels at bag-level are ...
To this end, we propose Multi-Instance Dynamic Ordinal Random Fields (MI-DORF). In this framework, we treat instance-labels as temporally-dependent latent variables in an Undirected Graphical Model. ...
In order to learn the model F from T , it is necessary to incorporate prior knowledge defining the Multi-Instance relation between labels y and latent ordinal states h. ...

Here, we describe and compare three techniques for transfer learning: multi-task, difference, and explicit latent variable architectures. ...
For activation energies of steps in NO reduction, the explicit latent variable method is not only the most accurate, but also enjoys cancellation of errors in functions that depend on multiple tasks. ...
Unlike multi-task learning and explicit latent variables, difference learning cannot be used directly for multi-class classification. ...

In multi-label learning, instances have a large number of noisy and irrelevant features, and each instance is associated with a set of class labels wherein label information is generally incomplete. ...
