This paper introduces a new algorithm for approximate mining of frequent patterns from streams of transactions using a limited amount of memory. The proposed algorithm consists in the computation of frequent itemsets in recent data and an effective method for inferring the global support of previously infrequent itemsets. Both upper and lower bounds on the support of each pattern found are retu...

The study of transportability aims to identify conditions under which causal information learned from experiments can be reused in a different environment where only passive observations can be collected. The theory introduced in [Pearl and Bareinboim, 2011] (henceforth [PB, 2011]) defines formal conditions for such transfer but falls short of providing an effective procedure for deciding wheth...

Over the years, the amount of information avmlable electromcally has grown mamfold There Is an increasing demand for automatic methods for text summarization Dommnindependent techniques for automauc summanzation by paragraph extractton have been proposed m (Salton et al , 1994, Salton et al , 1996b) In tins study, we attempt to evainate these methods by companng the automatlcally generated extr...

To extract terminological knowledge from data, Baader and Distel have proposed an effective method that allows for the extraction of a base of all valid general concept inclusions of a given finite interpretation. In previous works, to be able to handle small amounts of errors in our data, we have extended this approach to also extract general concept inclusions which are “almost valid” in the ...

Using the effective complexity measure, proposed by M. Gell-Mann and S. Lloyd, we give a quantitative definition of an emergent property. We use several previous results and properties of this particular information measure closely related to the random features of the entity and its regularities.

Programming robots by human demonstration is an effective method for task-level robot programming. Robot programming for contact tasks such as assembly, where both motion and forces need to be controlled, requires an understanding of the interaction with the environment and cannot eeectively be accomplished by playing back recorded trajectories. Furthermore, since human demonstration is used to...

‘Distribution regression’ refers to the situation where a response Y depends on a covariate P where P is a probability distribution. The model is Y = f(P ) + μ where f is an unknown regression function and μ is a random error. Typically, we do not observe P directly, but rather, we observe a sample from P . In this paper we develop theory and methods for distribution-free versions of distributi...

One of the teaching methods available to teachers in the ‘andragogic’ model of teaching is the method of ‘Socratic Seminars’. This is a teacher-directed form of instruction in which questions are used as the sole method of teaching, placing students in the position of having to recognise the limits of their knowledge, and hopefully, motivating them to learn. This paper aims at initiating the di...

Materials are precious resources. Different methods are employed to protect the material from degradation. Thermal spraying is one of the most effective method to protect the material from wear, high temperature corrosion, stresses and erosion, thus increasing the life of material in use. Detonation gun spraying is one of the thermal spraying techniques known for providing hard, wear resistant ...
