CSE 494 CSE / CBS 598 ( Fall 2007 ) : Numerical Linear Algebra for Data Exploration — Two dimensional SVD and PCA

• Let Ai ∈ IRr×c, for i = 1, · · · , n, be the n data points in the training set, where r and c denote the number of rows and columns respectively for each Ai. We aim to compute two matrices L ∈ IRr×`1 and R ∈ IRc×`2 with orthonormal columns, and n matrices Mi ∈ IR`1×`2 , for i = 1, · · · , n, such that LMiR approximates Ai, for all i. Here, `1 and `2 are two prespecified parameters that are be...

QUERY PROCESSING OVER INCOMPLETE AUTONOMOUS WEB DATABASES by Hemal Khatri

Incompleteness due to missing attribute values (aka “null values”) is very common in autonomous web databases, on which user accesses are usually supported through mediators. Traditional query processing techniques that focus on the strict soundness of answer tuples often ignore tuples with critical missing attributes, even if they wind up being relevant to the user query. Ideally, the mediator...

Accumulation profiles of PrPSc in hemal nodes of naturally and experimentally scrapie-infected sheep

BACKGROUND In classical scrapie, the disease-associated abnormal isoform (PrP(Sc)) of normal prion protein accumulates principally in the nervous system and lymphoid tissues of small ruminants. Lymph nodes traffic leukocytes via lymphatic and blood vasculatures but hemal nodes lack lymphatic vessels and thus traffic leukocytes only via the blood. Although PrP(Sc) accumulation profiles are well-...

CSE 190A Project Proposal: 3D Photography

This paper presents a research proposal for CSE 190A: Projects in Vision and Learning, Winter 2007, on the subject of 3D photography. It addresses the objectives, datasets, milestones, and student qualifications for the project.
