A Formal Framework and New Related Methods when Fancing with Granularity in Unsupervised Learning
نویسنده
چکیده
Classical data mining methods are currently involved in the descriptive forming of information granules. However, this is the first level of abstraction. Afterwards, we are facing with a new challenge: processing information granules and organizing them into more complex cognitive structures. There are several formal frameworks in which information granules are built, captured or processed: Fuzzy sets, Rough sets, Shadowed sets, Modal sets, Interval mathematics and so on. This paper is intended to consider multidimensional fuzzy granules as primary events (genuine outcomes of a set of fuzzyvalued random variables) and to address a second level of abstraction by using knowledge discovery methods based on the granular computing paradigm.

Identification of Power Stripping Resources with Fuzzy Cluster Dynamic Approach (Case Study: West Azerbaijan Province)
Reducing electric power theft is a significant part of the potential benefits of implementing the concept of smart grid. This paper proposes a data-based approach to identify locations with unusual electricity consumption. The new distance-based method classifies the new data as violator costumers, if their distance is long to the primary consumption data. The proposed algorithm determines the ...
متن کاملDeep Unsupervised Domain Adaptation for Image Classification via Low Rank Representation Learning
Domain adaptation is a powerful technique given a wide amount of labeled data from similar attributes in different domains. In real-world applications, there is a huge number of data but almost more of them are unlabeled. It is effective in image classification where it is expensive and time-consuming to obtain adequate label data. We propose a novel method named DALRRL, which consists of deep ...

متن کاملA Unifying Framework for Temporal Abstraction in Stochastic Processes
This paper presents a framework for unifying the large and growing body of literature that deals with what broadly can be defined as temporal abstraction in Markov Decision Processes (MDPs). MDPs provide an appealing formal framework for modeling a large variety of stochastic problems. The main drawback of this approach is that a requirement of the formal model, i.e., the Markov property, typic...
