Knowledge Propagation over Conditional Independence Graphs
Urszula Chajewska, Harsh Shrivastava
Conditional Independence (CI) graph is a special type of a Probabilistic Graphical Model (PGM) where the feature connections are modeled using an undirected graph and the edge weig…
Defining Explanation in Probabilistic Systems
Urszula Chajewska, Joseph Y. Halpern
As probabilistic systems gain popularity and are coming into wider use, the need for a mechanism that explains the system's findings and recommendations becomes more critical. The…
Utility Elicitation as a Classification Problem
Urszula Chajewska, Lise Getoor, Joseph Norman +1
We investigate the application of classification techniques to utility elicitation. In a decision problem, two sets of parameters must generally be elicited: the probabilities and…
Utilities as Random Variables: Density Estimation and Structure Discovery
Urszula Chajewska, Daphne Koller
Decision theory does not traditionally include uncertainty over utility functions. We argue that the a person's utility value for a given outcome can be treated as we treat other d…
Aggregating Learned Probabilistic Beliefs
Pedrito Maynard-Reid, Urszula Chajewska
We consider the task of aggregating beliefs of severalexperts. We assume that these beliefs are represented as probabilitydistributions. We argue that the evaluation of any aggrega…
