Detecting Interesting Instances
نویسنده
چکیده
Most valid rules that are learned from very large and high dimensional data sets are not interesting, but are already known to the users. The dominant model of the overall data set may well suppress the interesting local patterns. The search for interesting local patterns can be implemented by a two step learning approach which rst acquires the global models before it focuses on the rest in order to detect local patterns. In this paper, three sets of interesting instances are distinguished. For these sets, the hypothesis space is enlarged in order to characterize local patterns in a second learning step.

New experiments with bright positron and positronium beams
After half a century of work studying the interaction of positrons with ordinary matter, there remain several interesting fundamental questions that are uniquely suitable for investigation using antimatter, and several instances where interesting views of the world could be obtained using positrons. In this paper we examine the possibilities for imaging single molecules with positrons and for l...
متن کاملFast Detection of Unsolvable Planning Instances Using Local Consistency
There has been a tremendous advance in domain-independent planning over the past decades, and planners have become increasingly efficient at finding plans. However, this has not been paired by any corresponding improvement in detecting unsolvable instances. Such instances are obviously important but largely neglected in planning. In other areas, such as constraint solving and model checking, mu...
متن کاملDetecting noisy instances with the rule-based classification model
The performance of a classification model is invariably affected by the characteristics of measurement data it is built upon. If quality of the data is generally poor, then the classification model will demonstrate poor performance. The amount of noisy instances present in a given dataset is a good reflection of quality of the data. The detection and removal of noisy data instances will improve...
متن کاملTowards Detecting Counter-considerations in Text
Argumentation mining obviously involves finding support relations between statements, but many interesting instances of argumentation also contain counter-considerations, which the author mentions in order to preempt possible objections by the readers. A counterconsideration in monologue text thus involves a switch of perspective toward an imaginary opponent. We present a classification approac...
متن کاملIdentifying the software and their families using the exploration techniques of sequential patterns in dynamic analysis
Nowadays, crypto-ransomware is considered as one of the most threats in cybersecurity. Crypto ransomware removes data access by encrypting valuable data and requests a ransom payment to allow data decryption. As ransomware is still new in the field of cybersecurity, there are few pieces of research focusing on detecting ransomware samples. Most published works considered System File and process...
