What makes unlearning hard and what to do about it

no code implementations3 Jun 2024 Kairan Zhao, Meghdad Kurmanji, George-Octavian Bărbulescu, Eleni Triantafillou, Peter Triantafillou

Based on our insights, we develop a framework coined Refined-Unlearning Meta-algorithm (RUM) that encompasses: (i) refining the forget set into homogenized subsets, according to different characteristics; and (ii) a meta-algorithm that employs existing algorithms to unlearn each subset and finally delivers a model that has unlearned the overall forget set.

To Each (Textual Sequence) Its Own: Improving Memorized-Data Unlearning in Large Language Models

no code implementations6 May 2024 George-Octavian Barbulescu, Peter Triantafillou

LLMs have been found to memorize training textual sequences and regurgitate verbatim said sequences during text generation time.

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.

Graphical Join: A New Physical Join Algorithm for RDBMSs

no code implementations21 Jun 2022 Ali Mohammadi Shanghooshabad, Peter Triantafillou

The results for in-memory join computation show performance improvements up to 64X, 388X, and 6X faster than PostgreSQL, MonetDB and Umbra, respectively.

Model Joins: Enabling Analytics Over Joins of Absent Big Tables

no code implementations21 Jun 2022 Ali Mohammadi Shanghooshabad, Peter Triantafillou

Q3: As the model join would be an approximation of the actual data join, how can one evaluate the quality of the model join result?

ML-AQP: Query-Driven Approximate Query Processing based on Machine Learning

2 code implementations14 Mar 2020 Fotis Savva, Christos Anagnostopoulos, Peter Triantafillou

As more and more organizations rely on data-driven decision making, large-scale analytics become increasingly important.

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.
