Probabilistic Graphical Models for Credibility Analysis in Evolving Online Communities [article]

Subhabrata Mukherjee
2017 arXiv   pre-print
To this end, we devise new models based on Conditional Random Fields for different settings like incorporating partial expert knowledge for semi-supervised learning, and handling discrete labels as well  ...  Prior works in this domain operate on a static snapshot of the community, making strong assumptions about the structure of the data (e.g., relational tables), or consider only shallow features for text  ...  During the test phase for a "long-tail" user, we take her parameters from the background model. We set the number of facets as Z = 50, and number expertise levels as E = 5, for all the datasets.  ...

Conditional Graphical Models for Protein Structural Motif Recognition

Yan Liu, Jaime Carbonell, Vanathi Gopalakrishnan, Peter Weigele
2009 Journal of Computational Biology  
A new type of undirected graphical models are built based on protein structure graphs, whose nodes represent the state of either residues or a secondary structure element and whose edges represent interactions  ...  These cases necessitate a more expressive model to capture the structural properties of proteins, and therefore developing a family of such predictive models is the core of this dissertation.  ...  Therefore we follow and extend the graphical model approaches and develop a series of new models for protein structure prediction.  ...
