HotKeys must be considered in design to prevent them from being generated in a database. Add caches in the service side to reduce HotKey issues. Multi-level cache should be used to solve the HotKey issue (such as Redis + local level-2 cache). Disable hotspot keys. For example, configu...
elements from this set. However, frequently the training data is too large to fit all at once, and this approach isn't feasible. Instead, we use a technique called reservoir sampling. Reservoir samplingis an algorithm for efficiently drawing random samples from a dataset ...

identify bias in each peer's sample and explain how you think they could remove the bias from their sample. By using convenience sampling, Susan would be choosing students, not so much at random, but by accessibility. Because of this, her...
With this work, we intend to fill that gap by proposing a model to predict the preference for a wide range of tourist attractions, adapted from the “Thesaurus on Tourism and Leisure Activities” of the World Tourism Organization (Organization 2001), based on the tourists’ five personality ...
a cluster randomized trial to avoid conflating our experimental manipulation with schools’ characteristics, such as their size, socio-economic status (SES), educational philosophy, and to remove this unexplained between-school variability from the between-group main effect, thereby increasing statistical ...
Each of the Europeans and Africans are assigned a great majority of their ancestry from one of them. African–Americans are inferred to have an average of 18% ancestry from the European cluster but with substantial inter-individual variation14. Assignment of clusters in this case is readily ...
In Table 1, Raw Data (RD) refers to the original raw data with missing values we initially obtained. Complete Data (CD) repre- sents a complete dataset without any missing value after we iteratively remove variables and subjects with large missing value percentage. CDs contain no missing ...
In response to the concern regarding aggregation bias, recent studies have adopted a more granular approach to investigate the effects of CSP by examining various CSP indicators relevant to specific stakeholder groups (Baird et al.2012; Rehbein et al.2004). For instance, Salama et al. (2011) ...
To characterize the periodicities present in the unnormalized data set, we calculated the phase of peak transcript levels and amplitudes for all protein-coding transcripts from the DFT component corresponding to the two LD cycles. Since our samples were taken at non-equidistant sampling intervals, the...
