Complementarity in Human-AI Collaboration: Concept, Sources, and Evidence

1 code implementation21 Mar 2024 Patrick Hemmer, Max Schemmer, Niklas Kühl, Michael Vössing, Gerhard Satzger

Our work provides researchers with a theoretical foundation of complementarity in human-AI decision-making and demonstrates that leveraging sources of complementarity potential constitutes a viable pathway toward effective human-AI collaboration.

On the Effect of Contextual Information on Human Delegation Behavior in Human-AI collaboration

no code implementations9 Jan 2024 Philipp Spitzer, Joshua Holstein, Patrick Hemmer, Michael Vössing, Niklas Kühl, Dominik Martin, Gerhard Satzger

In this work, we explore the effects of providing contextual information on human decisions to delegate instances to an AI.

Navigating the Synthetic Realm: Harnessing Diffusion-based Models for Laparoscopic Text-to-Image Generation

3 code implementations5 Dec 2023 Simeon Allmendinger, Patrick Hemmer, Moritz Queisner, Igor Sauer, Leopold Müller, Johannes Jakubik, Michael Vössing, Niklas Kühl

We demonstrate the usage of state-of-the-art text-to-image architectures in the context of laparoscopic imaging with regard to the surgical removal of the gallbladder as an example.

Redefining the Laparoscopic Spatial Sense: AI-based Intra- and Postoperative Measurement from Stereoimages

1 code implementation16 Nov 2023 Leopold Müller, Patrick Hemmer, Moritz Queisner, Igor Sauer, Simeon Allmendinger, Johannes Jakubik, Michael Vössing, Niklas Kühl

A significant challenge in image-guided surgery is the accurate measurement task of relevant structures such as vessel segments, resection margins, or bowel lengths.

Improving the Efficiency of Human-in-the-Loop Systems: Adding Artificial to Human Experts

1 code implementation6 Jul 2023 Johannes Jakubik, Daniel Weber, Patrick Hemmer, Michael Vössing, Gerhard Satzger

Hence, human-in-the-loop (HITL) extensions to ML models add a human review for instances that are difficult to classify.

Learning to Defer with Limited Expert Predictions

1 code implementation14 Apr 2023 Patrick Hemmer, Lukas Thede, Michael Vössing, Johannes Jakubik, Niklas Kühl

In this paper, we propose a three-step approach to reduce the number of expert predictions required to train learning to defer algorithms.

Human-AI Collaboration: The Effect of AI Delegation on Human Task Performance and Task Satisfaction

no code implementations16 Mar 2023 Patrick Hemmer, Monika Westphal, Max Schemmer, Sebastian Vetter, Michael Vössing, Gerhard Satzger

In an experimental study with 196 participants, we show that task performance and task satisfaction improve through AI delegation, regardless of whether humans are aware of the delegation.

Should I Follow AI-based Advice? Measuring Appropriate Reliance in Human-AI Decision-Making

no code implementations14 Apr 2022 Max Schemmer, Patrick Hemmer, Niklas Kühl, Carina Benz, Gerhard Satzger

However, recent work has shown that AI advice is not always beneficial, as humans have shown to be unable to ignore incorrect AI advice, essentially representing an over-reliance on AI.

DEAL: Deep Evidential Active Learning for Image Classification

2 code implementations22 Jul 2020 Patrick Hemmer, Niklas Kühl, Jakob Schöffer

By replacing the softmax standard output of a CNN with the parameters of a Dirichlet density, the model learns to identify data instances that contribute efficiently to improving model performance during training.
