Ge.tracker: a Robust, Lightweight Topic Tracking System
نویسندگان
چکیده
We describe a topic tracking system developed at GE R&D Center in connection with our participation in DARPA TDT evaluations. The TDT tracking task is specified as follows: given Nt training news stories on a topic, the system must find all subsequent stories on the same topic in all tracked news sources. These sources include radio and television news broadcasts, as well as newswire feeds. The initial set of training stories (usually 1, 2 or 4) is the only information about the topic available to the tracking system. The tracking performance is gauged using the False Alarm Rate and the Miss Rate metrics, reflecting the incidence of incorrect classification decisions made by the automatic system.

An Adaptive-Robust Control Approach for Trajectory Tracking of two 5 DOF Cooperating Robot Manipulators Moving a Rigid Payload
In this paper, a dual system consisting of two 5 DOF (RRRRR) robot manipulators is considered as a cooperative robotic system used to manipulate a rigid payload on a desired trajectory between two desired initial and end positions/orientations. The forward and inverse kinematic problems are first solved for the dual arm system. Then, dynamics of the system and the relations between forces/momen...
متن کاملRobust Sliding Mode Controller for Trajectory Tracking and Attitude Control of a Nonholonomic Spherical Mobile Robot
Based on dynamic modeling, robust trajectory tracking control of attitude and position of a spherical mobile robot is proposed. In this paper, the spherical robot is composed of a spherical shell and three independent rotors which act as the inner driver mechanism. Owing to rolling without slipping assumption, the robot is subjected to two nonholonomic constraints. The state space representatio...

This paper develops an improved robust multi-surface sliding mode controller for a complicated five degrees of freedom Underwater Vehicle-Manipulator System with floating base. The proposed method combines the robust controller with some corrective terms to decrease the tracking error in transient and steady state. This approach improves the performance of the nonlinear dynamic control scheme a...
متن کاملDesign of robust carrier tracking systems in high dynamic and high noise conditions, with emphasis on neuro-fuzzy controller
The robust carrier tracking is defined as the ability of a receiver to determine the phase and frequency of the input carrier signal in unusual conditions such as signal loss, input signal fading, high receiver dynamic, or other destructive effects of propagation. An implementation of tight tracking can be understood in terms of adopting a very narrow loop bandwidth that contradict with the req...
متن کاملTracking Control of Uncertain Non - Iinear MIMO System Using Modified Sliding Surfaces for Attitude Large Maneuver of Satellites on Orbit
Designing a robust tracking control for a non-linear MIMO system with uncertainty is one of the most complicated control problems. In this paper, sliding mode changed to non-linear controllable canonical form by input-output linearization. This, sliding surfaces can be defined in a way that we can de-couple equations and indicate the sliding conditions of multi-variable controller system. The u...
