Chapter # ALGORITHM COMBINATION FOR IMPROVED PERFORMANCE IN BIOSUVEILLANCE Algorithms Combination for Improved Surveillance

چکیده
This chapter proposes an enhancement to currently used algorithms for monitoring daily counts of pre-diagnostic data. Rather than use a single algorithm or apply multiple algorithms simultaneously, our approach is based on ensembles of algorithms. The ensembles lead to better performance in terms of higher true alert rates for a given false alert rate. Combinations can be employed at the data pre-processing step and/or at the monitoring step. We discuss the advantages of such an approach and illustrate its usefulness using authentic modern biosurveillance data.

Ball Trajectory Estimation and Robot Control to Reach the Ball Using Single Camera
In robotics research, catching a projectile object with a robotic system is one of the challenging problems. The outcome of these researches can be used in a wide range of applications such as video surveillance systems, analysis of sports videos, monitoring programs for human activities, and human-machine interactions. In this paper, we propose a new vision-based algorithm to estimate the traj...
متن کاملComprehensive Analysis of Dense Point Cloud Filtering Algorithm for Eliminating Non-Ground Features
Point cloud and LiDAR Filtering is removing non-ground features from digital surface model (DSM) and reaching the bare earth and DTM extraction. Various methods have been proposed by different researchers to distinguish between ground and non- ground in points cloud and LiDAR data. Most fully automated methods have a common disadvantage, and they are only effective for a particular type of surf...
متن کاملA Novel Intelligent Energy Management Strategy Based on Combination of Multi Methods for a Hybrid Electric Vehicle
Based on the problems caused by today conventional vehicles, much attention has been put on the fuel cell vehicles researches. However, using a fuel cell system is not adequate alone in transportation applications, because the load power profile includes transient that is not compatible with the fuel cell dynamic. To resolve this problem, hybridization of the fuel cell and energy storage device...

In this paper, the performance of PSO on GA isdiscussed and a new algorithm as PSOGA is proposed for the net...
متن کاملPerformance evaluation of block-based copy- move image forgery detection algorithms
Copy-move forgery is a particular type of distortion where a part or portions of one image is/are copied to other parts of the same image. This type of manipulation is done to hide a particular part of the image or to copy one or more objects into the same image. There are several methods for detecting copy-move forgery, including block-based and key point-based methods. In this paper, a method...
