Human-AI Co-Creativity: Exploring Synergies Across Levels of Creative Collaboration
Jennifer Haase, Sebastian Pokutta
Human-AI co-creativity represents a transformative shift in how humans and generative AI tools collaborate in creative processes. This chapter explores the synergies between human…
S-CFE: Simple Counterfactual Explanations
Shpresim Sadiku, Moritz Wagner, Sai Ganesh Nagarajan +1
We study the problem of finding optimal sparse, manifold-aligned counterfactual explanations for classifiers. Canonically, this can be formulated as an optimization problem with mu…
Flexible block-iterative analysis for the Frank-Wolfe algorithm
Gábor Braun, Jannis Halbey, Sebastian Pokutta +1
We prove that the block-coordinate Frank-Wolfe (BCFW) algorithm converges with state-of-the-art rates in both convex and nonconvex settings under a very mild "block-iterative" assu…
Better bounds on finite-order Grothendieck constants
Sébastien Designolle, Tamás Vértesi, Sebastian Pokutta
Grothendieck constants bound the advantage of -dimensional strategies over -dimensional ones in a specific optimisation task. They have applications ranging from app…
The Pivoting Framework: Frank-Wolfe Algorithms with Active Set Size Control
Elias Wirth, Mathieu Besançon, Sebastian Pokutta
We propose the pivoting meta algorithm (PM) to enhance optimization algorithms that generate iterates as convex combinations of vertices of a feasible region $C\subseteq \mathbb{R}…
Fast convergence of Frank-Wolfe algorithms on polytopes
Elias Wirth, Javier Pena, Sebastian Pokutta
We provide a template to derive convergence rates for the following popular versions of the Frank-Wolfe algorithm on polytopes: vanilla Frank-Wolfe, Frank-Wolfe with away steps, Fr…
