We consider a novel distributed learning problem: A server receives potentially unlimited data from clients in a sequential manner, but only a small initial fraction of these data are labeled. Because communication bandwidth is expensive, each client is limited to sending the server only a small (high-priority) fraction of the unlabeled data it generates, and the server is limited in the amount of...
On the basis of regular expression, by rational extension and reconstruction, the concept of homologous regular expressions(abbreviated to HRegExp) is put forward. The syntax structure and element organization of simple data type and complex data type in schemas can be described perfectly by using HRegExp. Algorithms for analysing and extracting the HRegExp from various GML schemas are introduced.
