Long-tail entity distributions
Web18 de set. de 2024 · Degree bias makes long-tail entities and relations more likely to be sampled so that the information between norm entities and long-tail entities is balanced. How much this biased random walk can help is limited by the original entity distribution in KGs, but the improvement made from SAEA w/o DB to SAEA is justifiable. Web29 de jun. de 2024 · Figure 1: This type of distribution, in which there are a few common categories followed by many rare categories, is called a long tail distribution. In the majority of deep learning applications, datasets collected in the real world tend to have this long-tail shape. Figure 2: Long tail distributions occur frequently in the real world.

Additionally all the dfs in the pot-domain of attraction of a Pareto df are heavy-tailed. If the density has a high central peak and long tails, then the kurtosis is typically large. A df with kurtosis larger than 3 is fat-tailed or leptokurtic.
