Strong and weak sampling are two sampling approach in Statistics, and are popular in computational cognitive science and language learning[1]. In strong sampling, it is assumed that the data are intentionally generated as positive examples of a concept[2], while in weak sampling, it is assumed that the data are generated without any restrictions.[3]

Formal Definition

In strong sampling, we assume observation is randomly sampled from the true hypothesis:

In weak sampling, we assume observations randomly sampled and then classified:
