Model interpretability through the lens of computational complexity

P Barceló, M Monet, J Pérez… - Advances in neural …, 2020 - proceedings.neurips.cc
In spite of several claims stating that some models are more interpretable than others--eg,"
linear models are more interpretable than deep neural networks"--we still lack a principled …

On computing probabilistic abductive explanations

Y Izza, X Huang, A Ignatiev, N Narodytska… - International Journal of …, 2023 - Elsevier
The most widely studied explainable AI (XAI) approaches are unsound. This is the case with
well-known model-agnostic explanation approaches, and it is also the case with approaches …

Hindsight learning for mdps with exogenous inputs

SR Sinclair, FV Frujeri, CA Cheng… - International …, 2023 - proceedings.mlr.press
Many resource management problems require sequential decision-making under
uncertainty, where the only uncertainty affecting the decision outcomes are exogenous …

Counting keys in parallel after a side channel attack

DP Martin, JF O'connell, E Oswald, M Stam - Advances in Cryptology …, 2015 - Springer
Side channels provide additional information to skilled adversaries that reduce the effort to
determine an unknown key. If sufficient side channel information is available, identification of …

On approximating total variation distance

A Bhattacharyya, S Gayen, KS Meel… - arxiv preprint arxiv …, 2022 - arxiv.org
Total variation distance (TV distance) is a fundamental notion of distance between
probability distributions. In this work, we introduce and study the computational problem of …

Pseudorandom generators for polynomial threshold functions

R Meka, D Zuckerman - Proceedings of the Forty-second ACM …, 2010 - dl.acm.org
We study the natural question of constructing pseudorandom generators (PRGs) for low-
degree polynomial threshold functions (PTFs). We give a PRG with seed-length log n/εO (d) …

Approximate counting via correlation decay in spin systems

L Li, P Lu, Y Yin - Proceedings of the twenty-third annual ACM-SIAM …, 2012 - SIAM
We give the first deterministic fully polynomial-time approximation scheme (FPTAS) for
computing the partition function of a two-state spin system on an arbitrary graph, when the …

A simple near-linear pseudopolynomial time randomized algorithm for subset sum

C **, H Wu - arxiv preprint arxiv:1807.11597, 2018 - arxiv.org
Given a multiset $ S $ of $ n $ positive integers and a target integer $ t $, the Subset Sum
problem asks to determine whether there exists a subset of $ S $ that sums up to $ t $. The …

On computing relevant features for explaining NBCs

Y Izza, J Marques-Silva - arxiv preprint arxiv:2207.04748, 2022 - arxiv.org
Despite the progress observed with model-agnostic explainable AI (XAI), it is the case that
model-agnostic XAI can produce incorrect explanations. One alternative are the so-called …

A deterministic polynomial-time approximation scheme for counting knapsack solutions

D Štefankovič, S Vempala, E Vigoda - SIAM Journal on Computing, 2012 - SIAM
Given n elements with nonnegative integer weights w_1,...,w_n and an integer capacity C,
we consider the counting version of the classic knapsack problem: find the number of distinct …
