Abstract

A two-step optimization method called inference functions for margins (IFM) is broadly adopted to estimate Copula-GARCH models. However, IFM is subject to small-sample bias. This paper proposes to estimate Copula-GARCH models by applying Maximization by Parts (MBP), a multi-step optimization algorithm. This method decomposes the complicated log likelihood into two parts. In the decomposition, the first part is an easy likelihood consisting of only marginal likelihoods. The second part includes dependence parameters from a multivariate likelihood and is used to update the estimates from the first part. The results indicate that MBP can provide more efficient estimation than IFM.

8. An Image Annotation Guide Agent.

Abstract

The performance of retrieving an image in terms of text-type of queries depends heavily on the quality of the annotated descriptive metadata that describes the content of the images. However, the effective annotation of an image can often be a laborious task that requires consistent domain knowledge. Annotators may annotate features in the images that could not contribute much to retrieval of the images. For effective annotation, an annotation guide agent (AGA) is proposed to aid annotators. Basically AGA monitors the annotator's behaviors and based on the common sense induced from previous annotation instances as well as the domain ontology suggests critical property that will yield the most valuable information for image retrieval. We showed by experiments that the critical property and common sense heuristics used by AGA to aid the annotation of images could significantly lead to the improvement of the recall and precision of image retrieval.
