Fiber LDA System

1987
Velocity is one of the most interesting physical quantities to detect for the control of industrial manufacturing processes as well as for the determination of vector components of a moving object in the physical science. Among the variety of methods to measure the velocity, it is desirable to detect velocity without disturbing the motion of the moving

The collocation model based on LDA

SPIE Proceedings, 2015
LDA is a probabilistic topic model to discover the hidden thematic structure in large archives of documents. LDA-Col model is an extended model based on LDA model. In this paper, we introduced LDA-Col model in detail, including the plate notation, generative process and inference.

PCA/LDA Applications in Biometrics

2006
In this chapter, we show some PCA/LDA applications in biometrics. Based on the introductions to both PCA and LDA mentioned in Chapters II and III, their simple descriptions are given first. Then, we indicate a significant application in face recognition. The next sections discuss palmprint identification and gait verification, respectively.

LDA Principles and Laser Optics

2010
The technique of Laser Doppler Anemometry (LDA), as the name stands for, is a technique of using the laser light and the Doppler effect for velocity measurements. It is an optical method and hence tightly related to both the physical and geometrical optics.
