WebExisting long-tailed recognition methods, aiming to train class-balanced models from long-tailed data, generally assume the models would be evaluated on the uniform test class distribution. However, practical test class distributions often violate this assumption (e.g., being either long-tailed or even inversely long-tailed), which may lead existing methods to …
WebMar 26, 2024 · How do you remember that? For a one-tailed test if you want an alpha = 0.05 it’s just alpha/number of tails so 0.05/1 = 0.05, but for a two-tailed test it’s 0.05/2 = 0.025. That’s why if you ever use a t-table they group one-tailed and two-tailed tests, see below.
