Finding Frequent Items over General Update Streams
We present novel space and time-efficient algorithms for finding frequent items over general update streams. Our algorithms are based on a novel adaptation of the popular dyadic intervals method for finding frequent items. The algorithms improve upon existing algorithms in both theory and practice.
متن کاملCounting Distinct Items over Update Streams
We present two novel algorithms for tracking the number of distinct items over high speed data streams consisting of insertion and deletion operations that improves on the space and time complexity of existing algorithms.
متن کاملAnswers to Question Box Items
A2. This is a very interesting question. In antimicrobial research, the ability of an antibiotic to produce a three-log kill (decrease the bacterial load by three logs) is an important characteristic. In theory, if an antibiotic is able to produce a threelog kill, the host’s immune system can usually kill the remaining bacterial population. However, with an immunocompromised host, such as an HI...
متن کاملFinding frequent items over sliding windows with constant update time
a r t i c l e i n f o a b s t r a c t In this paper, we consider the problem of finding-approximate frequent items over a sliding window of size N. A recent work by Lee and Ting (2006) [7] solves the problem by giving an algorithm that supports O (1) query and update time, and uses O (1) space. Their query time and memory usage are essentially optimal, but the update time is not. We give a new ...
متن کاملDoes remembering emotional items impair recall of same-emotion items?
In the part-set cuing effect, cuing a subset of previously studied items impairs recall of the remaining noncued items. This experiment reveals that cuing participants with previously-studied emotional pictures (e.g., fear-evoking pictures of people) can impair recall of pictures involving the same emotion but different content (e.g., fear-evoking pictures of animals). This indicates that new e...
