Towards Unbounded Machine Unlearning

1 code implementation NeurIPS 2023 Meghdad Kurmanji, Peter Triantafillou, Jamie Hayes, Eleni Triantafillou

This paper is the first, to our knowledge, to study unlearning for different applications (RB, RC, UP), with the view that each has its own desiderata, definitions for `forgetting' and associated metrics for forget quality.

Explaining Aggregates for Exploratory Analytics

no code implementations29 Dec 2018 Fotis Savva, Christos Anagnostopoulos, Peter Triantafillou

Analysts wishing to explore multivariate data spaces, typically pose queries involving selection operators, i. e., range or radius queries, which define data subspaces of possible interest and then use aggregation functions, the results of which determine their exploratory analytics interests.
