PRML - THE TEAM
PRML SNAPSHOT I:SCENE ANALYSIS AND NOVELTY DETECTION (PHD WORK BY VIVIAN YONG)
FrameworkWorkaround the challenges of object recognitionLabel over-segmented imagesModel the cooccurrence of labels in neighbourhoodNovelty detection from a simple MoG criterion using Mahalanobis metric
PRML SNAPSHOT 1I:EVENT CLASSIFICATION / ANOMALY DETECTION (PHD WORK BY HANHE LIN)
Feature Extraction: Optical flow histogram undergoing Quantization and Binary Coding (QBC)
PETS dataset.CAIR feature evaluation: best n=3 or 4.6 Events shown in 3-D manifolds: walking, running, local movement, local dispersion, splitting, formation, evacuation.
PRML SNAPSHOT III:VIDEO STREAMING ON AD HOC MULTI-HOP NETWORKS (PHD WORK BY YUWEI XU)
Neighbor nodes have interferenceNodes have limited storageIndependently modeled as M/M/1/KHowever, processing rates mu not known.Method
From lambda, lambda_d, queue length, estimate muMinimize total delay
FUTURE TALKS
Technical
Probabilistic modeling in information processing (overview, recent advances, PRML research highlights)
Similarity measures - interesting alternatives other than Euclidean distance, with applications in information retrieval, pattern recognition, and more
Non-technical
