Improved Maximum Mutual Information Estimation Training of Continuous Density HMMs
We derive a new set of equations for MMIE based on a quasi-Newton algorithm, without relying on EBW. We find that by adopting a generalized form of the MMIE criterion,…

A Framework for Robust 3-D Change Detection
We present an application of our framework for 3-D object-centered change detection to combined satellite and aerial imagery.

Observations on Overlap: Findings and Implications for Automatic Processing of Multi-Party Conversation
We examine the distribution of overlapping speech in different corpora of natural multi-party conversations, including two types of meetings, and two corpora of telephone conversations.

Detecting Independently Moving Objects and Their Interactions in Georeferenced Airborne Video
In this paper, we describe a novel technique for detecting independent movement by analyzing georeferenced object motion relative to the trajectory of the camera. The method is demonstrated on over…

A broad host range replicon with different requirements for replication initiation in three bacterial species
To examine initiation events in bacteria unrelated to Escherichia coli, the genes encoding the replicative helicase, DnaB, of Pseudomonas putida and Pseudomonas aeruginosa were isolated and used to construct protein…

Weighting Schemes for Audio-visual Fusion in Speech Recognition
In this work we demonstrate an improvement in the state-of-the-art large vocabulary continuous speech recognition (LVCSR) performance, under clean and noisy conditions, by the use of visual information, in addition…
