A v-optimal histogram is based on the concept of minimizing a quantity which is called the weighted variance in this context. [1] This is defined as = =, where the histogram consists of J bins or buckets, n j is the number of items contained in the jth bin and where V j is the variance between the values associated with the items in the jth bin.
Prometheus is a free software application used for event monitoring and alerting. [2] It records metrics in a time series database (allowing for high dimensionality ) built using an HTTP pull model , with flexible queries and real-time alerting.
An example of histogram matching. In image processing, histogram matching or histogram specification is the transformation of an image so that its histogram matches a specified histogram. [1] The well-known histogram equalization method is a special case in which the specified histogram is uniformly distributed. [2]
Smale's problems is a list of eighteen unsolved problems in mathematics proposed by Steve Smale in 1998 [1] and republished in 1999. [2] Smale composed this list in reply to a request from Vladimir Arnold, then vice-president of the International Mathematical Union, who asked several mathematicians to propose a list of problems for the 21st century.
The problem can be approached using either frequentist inference or Bayesian inference, leading to different results. Estimating the population maximum based on a single sample yields divergent results, whereas estimation based on multiple samples is a practical estimation question whose answer is simple (especially in the frequentist setting ...
The New York Yankees are bringing in another veteran hitter this offseason, signing first baseman Paul Goldschmidt to a reported one-year, $12.5 million deal, per multiple reports.
It is still an open problem whether there are infinitely many -regular (non-bipartite) Ramanujan graphs for any . In particular, the problem is open for d = 7 {\displaystyle d=7} , the smallest case for which d − 1 {\displaystyle d-1} is not a prime power and hence not covered by Morgenstern's construction.
Louisville punter Brady Hodges said he opted out of the Sun Bowl this week because the Cardinals' NIL collective did not pay money promised to him in September. Hodges posted on social media ...
