Maximum Likelihood Function used to Calculate Confidence of Association Rules in Market Baskets
In this paper 1 we are concerned in looking at different ways for calculating the strength of Association Rules in Market Basket data. The significance of Association rules is measured via support and confidence and the way they are used to identify the rules in a particular transaction of the form, “When a customer buys items A&B also buys item C”. The first part of this paper illustrates the ...
متن کاملVirtually Repelling Fixed Points
In this article, we study the notion of virtually repelling fixed point. We first give a definition and an interpretation of it. We then prove that most proper holomorphic mappings f : U → V with U contained in V have at least one virtually repelling fixed point. 1. Preliminaries Let f : (C, α) → (C, α) be a holomorphic germ fixing α. Definition 1. The multiplicity m of α as a fixed point of f ...
متن کاملDemons in Physics
Maxwell’s ”finite being” was born in 1867, as one ”who knows the paths and velocities of all the molecules” ([7], p.213), and who, unlike us, is ”clever enough” ([7], p.213), and can violate the second law of thermodynamics. It was baptized as a demon by Lord Kelvin ([7], p. 214), and ever since has fueled the discussions in the foundations of statistical mechanics. Since its inception, and con...
متن کاملThe Baskets Queue
FIFO Queues have over the years been the subject of significant research. Such queues are used as buffers both in a variety of applications, and in recent years as a key tool in buffering data in high speed communication networks. Overall, the most popular dynamic-memory lock-free FIFO queue algorithm in the literature remains the MS-queue algorithm of Michael and Scott. Unfortunately, this alg...
متن کاملGated molecular baskets.
In this review, we describe the construction of gated molecular baskets, discuss their mechanism of action in regulating the exchange of guests and illustrate the potential of these concave hosts to act as catalysts for controlling chemical reactions. Importantly, a number of computational and experimental studies have suggested that gated baskets ought to unfold their gates at the rim for perm...
