A Study Of Non-Datapath Cache Replacement Algorithms, Steven G. Lyons Jr.
A Study Of Non-Datapath Cache Replacement Algorithms, Steven G. Lyons Jr.
FIU Electronic Theses and Dissertations
Conventionally, caching algorithms have been designed for the datapath — the levels of memory that must contain the data before it gets made available to the CPU. Attaching a fast device (such as an SSD) as a cache to a host that runs the application workload are recent developments. These host-side caches open up possibilities for what are referred to as non-datapath caches to exist. Non-Datapath caches are referred to as such because the caches do not exist on the traditional datapath, instead being optional memory locations for data. As these caches are optional, a new capability is available to …
Combining Algorithms For More General Ai, Mark Robert Musil
Combining Algorithms For More General Ai, Mark Robert Musil
Undergraduate Research & Mentoring Program
Two decades since the first convolutional neural network was introduced the AI sub-domains of classification, regression and prediction still rely heavily on a few ML architectures despite their flaws of being hungry for data, time, and high-end hardware while still lacking generality. In order to achieve more general intelligence that can perform one-shot learning, create internal representations, and recognize subtle patterns it is necessary to look for new ML system frameworks. Research on the interface between neuroscience and computational statistics/machine learning has suggested that combined algorithms may increase AI robustness in the same way that separate brain regions specialize. In …

Organizing video search results in a list view is widely adopted by current commercial search engines, which cannot support efficient browsing for complex search topics that have multiple semantic facets. In this article, we propose to organize video search results in a highly structured way. Specifically, videos are placed on a semantic hierarchy that accurately organizes various facets of a given search topic. To pick the most suitable videos for each node of the hierarchy, we define and utilize three important criteria: relevance, uniqueness, and diversity. Extensive evaluations on a large YouTube video dataset demonstrate the effectiveness of our approach.
Modeling Video Hyperlinks With Hypergraph For Web Video Reranking, Hung-Khoon Tan, Chong-Wah Ngo, Xiao Wu
Modeling Video Hyperlinks With Hypergraph For Web Video Reranking, Hung-Khoon Tan, Chong-Wah Ngo, Xiao Wu
Research Collection School Of Computing and Information Systems
In this paper, we investigate a novel approach of exploiting visual-duplicates for web video reranking using hypergraph. Current graph-based reranking approaches consider mainly the pair-wise linking of keyframes and ignore reliability issues that are inherent in such representation. We exploit higher order relation to overcome the issues of missing links in visual-duplicate keyframes and in addition identify the latent relationships among keyframes. Based on hypergraph, we consider two groups of video threads: visual near-duplicate threads and story threads, to hyperlink web videos and describe the higher order information existing in video content. To facilitate reranking using random walk algorithm, the …
