Continuous Refinement of Agent Resource Estimates
The challenge we address is to reason about projected resource usage within a hierarchical task execution framework in order to improve agent effectiveness. Specifically, we seek to define and maintain…

Generalized Linear Kernels for One-Versus-All Classification: Application to Speaker Recognition
In this paper, we examine the problem of kernel selection for one-versus-all (OVA) classification of multiclass data with support vector machines (SVMs). We focus specifically on the problem of training…

Compositionality for Tightly Coupled Systems: a New Application of the Propositions-As-Types Interpretation
Although compositional techniques are being successfully employed in practice, the use of such techniques is often rather informal and intuitive, and typically a justification for correct behaviour of the composed…

Conflict Negotiation Among Personal Calendar Agents
We will demonstrate distributed conflict resolution in the context of personalized meeting scheduling. The demonstration will show how distributed constraint optimization can be used to facilitate interaction between cognitive agents…

Reduced Resolution Residual Coding for H.264-Based Compression System
This paper describes a macroblock-based mixed resolution video encoding system. By reducing the spatial resolution of some macroblock residuals intelligently, our preliminary experiments show up to 20% improvement in video…

Computer-Mediated Collaborative Reasoning and Intelligence Analysis
We introduce a framework spanning the entire collaborative thought process using the Angler and SEAS (Structured Evidential Argumentation System) applications. Angler encourages creative brainstorming while SEAS demands analytical reasoning. The…

NOMOS: A Semantic Web software framework for annotation of multimodal corpora
We present NOMOS, an open-source software framework for annotation, processing, and analysis of multimodal corpora.

Joint Segmentation and Classification of Dialog Acts in Multiparty Meetings
This paper investigates a scheme for joint segmentation and classification of dialog acts (DAs) of the ICSI Meeting Corpus based on hidden-event language models and a maximum entropy classifier for…

Combining Prosodic, Lexical and Cepstral Systems for Deceptive Speech Detection
We report on machine learning experiments to distinguish deceptive from nondeceptive speech in the Columbia-SRI-Colorado (CSC) corpus. Specifically, we propose a system combination approach using different models and features for…
