Uncovering the Full Potential of Visual Grounding Methods in VQA

1 code implementation15 Jan 2024 Daniel Reich, Tanja Schultz

In this study, we demonstrate that current evaluation schemes for VG-methods are problematic due to the flawed assumption of availability of relevant visual information.

Measuring Faithful and Plausible Visual Grounding in VQA

1 code implementation24 May 2023 Daniel Reich, Felix Putze, Tanja Schultz

Metrics for Visual Grounding (VG) in Visual Question Answering (VQA) systems primarily aim to measure a system's reliance on relevant parts of the image when inferring an answer to the given question.

Visually Grounded VQA by Lattice-based Retrieval

1 code implementation15 Nov 2022 Daniel Reich, Felix Putze, Tanja Schultz

Visual Grounding (VG) in Visual Question Answering (VQA) systems describes how well a system manages to tie a question and its answer to relevant image regions.

Adventurer's Treasure Hunt: A Transparent System for Visually Grounded Compositional Visual Question Answering based on Scene Graphs

no code implementations28 Jun 2021 Daniel Reich, Felix Putze, Tanja Schultz

With the expressed goal of improving system transparency and visual grounding in the reasoning process in VQA, we present a modular system for the task of compositional VQA based on scene graphs.

Monotonically convergent optimization in quantum control using Krotov's method

2 code implementations30 Aug 2010 Daniel Reich, Mamadou Ndong, Christiane P. Koch

For the 'standard' quantum control problem of a convex final-time functional, linear equations of motion and linear dependency of the Hamiltonian on the field, the second-order contribution is not required for monotonic convergence but can be used to speed up convergence.
