Shotgun Wedding

A tutorial review: Metabolomics and partial least squares-discriminant analysis--a marriage of convenience or a shotgun wedding.

The predominance of partial least squares-discriminant analysis (PLS-DA) used to analyze metabolomics datasets (indeed, it is the most well-known tool to perform classification and regression in metabolomics), can be said to have led to the point that not all researchers are fully aware of alternative multivariate classification algorithms. This may in part be due to the widespread availability...

Wholesale Poisoning at a Wedding Feast

at the wedding and sat down to the banquet in the afternoon ; of these 110 fewer than forty were subsequently seized with symptoms of irritant poisoning, the time of onset varying from four to sixteen hours after the meal. Five of the persons so attacked had died up to the date when the facts were placed 011 record, and as that was only some ten days after the occurrence, it is possible that ot...

Constructing Wedding Seating Plans: A Tabu Subject

This paper examines an interesting combinatorial optimisation problem that generalises both the graph colouring and k-partition problems. The problem has an interesting practical application in the construction of wedding seating plans, where we seek to assign equal numbers of guests to tables such that they are sat near friends and, perhaps more importantly, kept away from their enemies. We de...

Supplement: Empirical Shotgun Scalability Analysis Supplement: Empirical Shotgun Scalability Analysis

In this supplement, we analyze the system-level bottlenecks of Shotgun’s scalability on multicore. Currently, we are able to get maximum of about 3− 4× speedup on 8 cores. To analyze multicore performance, we run a series of tests which try to isolate effects of various factors. Our analysis indicates that Shotgun is held back by memory access, but we give suggestions for future improvements to...
