Enhancing Cloud Storage with Shareable Instances for Social Computing [article]

Ying Mao, Peizhao Hu
2020 arXiv   pre-print
The basic idea of our design is to utilize cloud instances to assist file operations.  ...  Because of the limit of storage, bandwidth, power consumption, and other resource restrictions, most existing cloud storage apps for smartphones do not keep local copies of files.  ...  File transfer between users' cloud storage spaces is also considered as a cloud-assisted operation in Skyfiles. Basically, a cloud instance is initialized and plays a role of relay node.  ...

A Unifying View on Instance Selection [chapter]

Thomas Reinartz
2001 Instance Selection and Construction for Data Mining  
In this paper, we consider instance selection as an important focusing task in the data preparation phase of knowledge discovery and data mining.  ...  First of all, we define a broader perspective on focusing tasks, choose instance selection as one particular focusing task, and outline the specification of concrete evaluation criteria to measure success  ...  If we use top down induction of decision trees to build the classifier, the number of nodes in the resulting decision tree represents the complexity of the result, for instance.  ...
