Arthāpatti (अर्थापत्ति) means postulation, derivation from circumstances.
Anupalabdhi (अनुपलब्धि), accepted only by Kumarila Bhatta sub-school of Mīmāṃsā, means non-perception, negative/cognitive proof. Anupalabdhi pramana suggests that knowing a negative, such as there is no jug in this room is a form of valid knowledge
