Framework for Performance Comparison of Classifiers
2012Data stream mining is the process of extracting knowledge structures from continuous, rapid data records. Classification is one of the task involved in data stream mining that maps data into predefined groups or classes. Most of the stream learning algorithms learn decision models that continuously evolve over time, run in resource-aware environments ...

A performance comparison of bitmap indexes
Proceedings of the tenth international conference on Information and knowledge management - CIKM'01, 2001We present a comparison of two new word-aligned schemes with some schemes for compressing bitmap indexes, including the well-known byte-aligned bitmap code (BBC). On both synthetic data and real application data, the new word-aligned schemes use only 50% more space, but perform logical operations on compressed data 12 times faster than BBC.

Performance comparison of line parametrizations
Proceedings., 11th IAPR International Conference on Pattern Recognition. Vol. IV. Conference D: Architectures for Vision and Pattern Recognition,, 2003The performance of the Hough transform depends on parametrization schemes as well as mapping procedures. Based on criteria such as normalized-variance and risk-ratio the authors find that normal parametrization is the best among the four frequently mentioned ones in literature, if uniform noise is present in the image space. >

Performance comparison of PBFDAF algorithms
ICECS'99. Proceedings of ICECS '99. 6th IEEE International Conference on Electronics, Circuits and Systems (Cat. No.99EX357), 2003This paper compares the feedback cancellation performance of different partitioned block frequency-domain adaptive filter (PBFDAF) algorithms. The comparison is made for the error level of the echo canceler of an open and closed loop system of a hearing instrument setup.

Comparison of QoS has become necessary in the competitive environment in which telecommunications service provider companies operate. Comparisons are important for users, regulators, service providers and network providers. The user needs to compare delivered performances of various providers within the country and perhaps to a lesser extent that of ...

A Comparison Procedure for IMUs Performance
2019Inertial measurement units (IMU) are, typically, a cluster of accelerometers, gyroscopes and magnetometers. Its use was introduced with military applications, being, nowadays, widely common on industrial applications, namely robot navigation. Since there are a lot of units in different cost ranges, it is proposed, in this paper, a procedure to compare ...

Performance Comparison of Scene Matching Techniques
IEEE Transactions on Pattern Analysis and Machine Intelligence, 1979The problem of matching two images of the same scene, taken by different sensors under different viewing geometries, is a challenging problem in the field of image processing and pattern recognition. The scenes are usually transformed so drastically by the different viewing geometries and sensor characteristics that it is extremely difficult, if not ...

Hypervisors Comparison and Their Performance Testing
2018This paper is devoted to comparing approaches to the implementation of virtualization based on the use of the most common hypervisors. The paper considers advantages of using virtual machines while creating modern network infrastructure; as well as this, it describes a number of experiments on starting different hypervisors in one selected host along ...

A comparison of armature performance
IEEE Transactions on Magnetics, 1986All electromagnetic launchers require that the launch package have an armature. The armature is the component in which the electromagnetic forces are generated. In this paper we examine "armature efficiency" as one measure of armature performance which permits direct comparison of metal, plasma, and hybrid armatures. Efficiency also translates directly
