Synonyms Ranked multimedia retrieval ; Aggregation algorithms for middleware systems ; Evaluation of fuzzy queries over multimedia systems Definition Traditionally, queries over structured (e.g., relational) data identify the exact matches for the queries. This exact-match query model is not appropriate ...
Query Refinement for Diverse Top-k Selection This repository contains the ① reproducibility package for running our experiments and ② the implementation of our algorithm, which may be imported and used as a Python library. If there are any issues evaluating the reproducibility package or otherwise ...
基于Skyline服务的Top-k选择方法
论文:Differentiable Patch Selection for Image Recognition 1.研究动机 (1)神经网络需要大量内存和计算来处理高分辨率图像,即使只有一小部分图像实际上对当前任务有用。 我们提出了一种基于可微分 Top-K 运算符的方法来选择输入中最相关的部分,以高效处理高分辨率图像。 (2)确定图像的哪些部分要保留、哪些部分要丢弃...
在一个top-k查询中,两个度量反应了性能:a selection condition & a ranking function. selection condition维度可能很高,ranking function不一定是线性的。 这篇文献提出了一个模型,叫做ranking cube,并定义了一个rank-ware measure,未解决curse of dimension,又提出了ranking flagments。

Top-p, also known as nucleus sampling, allows for a more dynamic selection of values to be sampled from. In top-p sampling, the model sums the probabilities of the most likely next values in descending order and stops when the sum reaches p. Only the values within this cumulative probabili...
