— A heuristic is proposed to address free parameter selection for Support Vector Machines, with the goals of improving generalization performance and providing greater insensitivity to training set selection. The many local extrema in these optimization problems make gradient descent algorithms impractical. The main point of the proposed heuristic is the(More)
Widespread adoption of digital eye-tracking systems requires a substantial drop in prices from current levels. In this paper, we examine the feasibility of creating a low-cost device to track the eye position of a computer user. The device operates in real-time using prototype Jitter software at over 9 frames per second on an Apple PowerBook laptop. The(More)

In this paper, we examine two dimensional transmission and three dimensional laminography, as implemented in two Automated X-Ray Inspection (AXI) industrial machines used for inspection of Surface Mount Technology (SMT) solder joint connections in electronics manufacturing: the Teradyne XStation and Agilent 5DX. Factors affecting x-ray image quality, such(More)
