sPlot: A QUICK INTRODUCTION

The paper advocates the use of a statistical tool dedicated to the exploration of data samples populated by several sources of events. This new technique, called sP lot, is able to unfold the contributions of the different sources to the distribution of a data sample in a given variable. The sP lot tool applies in the context of a Likelihood fit which is performed on the data sample to determin...

A Quick Introduction to Operads

Operads (or at least An and En operads, which is what we’ll focus on) are a formalism for discussing various degrees to which associativity and commutativity can fail. Suppose I have a space X with a multiplication μ : X ×X → X that is not associative. In particular, μ(−, μ(−,−)) and μ(μ(−,−),−) are two different ternary operations. One approach is to consider a space O(3) of ternary operations...

A Quick Introduction to Clouds

There is not yet a standard definition for cloud computing, but a good working definition is to say that clouds provide on demand resources or services over the Internet, usually at the scale and with the reliability of a data center. There are at least two different, but related, types of clouds: the first category of clouds is designed to provide computing instances on demand, while the secon...

A Quick Introduction to the Quasideterminant

The quasideterminant is a replacement for the determinant for matrices over noncommutative rings R. It was introduced in 1991 by Gelfand and Retakh [6] and extends the ideas of Heyting [11] from 1928. The quasideterminant—actually quasideterminants, there are n of them, one for each position (i, j) in a matrix A ∈ Mn(R)—is a recursively constructed rational function that requires the invertibil...
