Absent Objects

Infants interpret ambiguous requests for absent objects.

The current studies investigated 2 skills involved in 14- to 20- month-olds' ability to interpret ambiguous requests for absent objects: tracking others' experiences (Study 1) and representing links between speakers and object features across present and absent reference episodes (Study 2). In the basic task, 2 experimenters played separately with a different ball. The balls were placed in opaq...

Exploiting Metadata of Absent Objects for Proxy Cache Consistency

Caching at the Web proxy server plays an important role in reducing the response time, the network tra c, and the load of Web servers. Many recent studies have proposed and examined the replacement and consistency policies for the proxy cache, which plays a central role in the performance of caching components. For better performance, they exploit various metadata of Web objects, such as the re...

Fourteen-month-olds' decontextualized understanding of words for absent objects.

The majority of research examining infants' decontextualized word knowledge comes from studies in which words and pictures are presented simultaneously. However, comprehending utterances about unseen objects is a hallmark of language. Do infants demonstrate decontextualized absent object knowledge early in the second year of life? Further, to what extent do words evoke strictly prototypical rep...

Absent Multiple Kernel Learning

Multiple kernel learning (MKL) optimally combines the multiple channels of each sample to improve classification performance. However, existing MKL algorithms cannot effectively handle the situation where some channels are missing, which is common in practical applications. This paper proposes an absent MKL (AMKL) algorithm to address this issue. Different from existing approaches where missing...
