Luanzheng Guo/Anzheng Guolu

I am a second-year Ph.D. student in Computer Science at UC Merced where I am advised by Professor Dong Li. Currently my research interests lie in fault resilience problems on large-scale parallel systems. Previously I was working on Computer Vision topics with machine learning methods with Professor Jun Chu and Professor Chuhong Pan and Professor Shiming Xiang.

“Identification of the fault resilience logic for machine learning like algorithms on large scale system”, Mentor: Ignacio Laguna, Prof. Dong Li. (On-going)

view details
The target is to recognize the inner logic of some algorithms that why they can tolerate underneath faults of large scale system derived from device worn, cosmos radiation like neutrons, and temperature. And then coming up with a methodology to automatically detect the fault resilience logic of the algorithms.

“Analysis on application-level fault tolerance on large scale system”, advisor: Prof. Dong Li. (On-going)

view details
soft errors (transient faults) due to reasons like cosmic rays are already making an impact in industry, and so many internet companies suffer from it. Generally, the damage brought by soft errors can be rolled back with great overhead, so what should we do to solve the problem? One feasible way is to protect the data and make the program more robust. Our goal is to propose a metric to evaluate the vulnerability of data within specific program, which will be used as the criterion to estimate the degree of protection on each data.

finding a stable and efficient approach to calibrate the cameras fixed on the mobile robot. (Coding with C++)
1) there are four cameras, two panorama cameras and two navigation cameras. For the navigation cameras, I fixed their focal lengths. But for the panorama camera, the focal length could not be fixed; 2) discovered a problem that the calibration parameters of the panorama cameras could vary, as the robot is moving; 3) to address that, each time before taking pictures in 360 degrees, I stopped the robot and calibrated the panorama cameras with a fixed chessboard panel on the robot.
