The learning phases in NN: From Fitting the Majority to Fitting a Few

no code implementations16 Feb 2022 Johannes Schneider

The learning dynamics of deep neural networks are subject to controversy.

Mechanism Design with Informational Punishment

no code implementations4 Jan 2022 Benjamin Balzer, Johannes Schneider

We introduce \emph{informational punishment} to the design of mechanisms that compete with an exogenous status quo mechanism: Players can send garbled public messages with some delay, and others cannot commit to ignoring them.

Towards Trustworthy AutoGrading of Short, Multi-lingual, Multi-type Answers

no code implementations2 Jan 2022 Johannes Schneider, Robin Richner, Micha Riser

We also show how teachers can effectively control the type of errors made by the system and how they can validate efficiently that the autograder's performance on individual exams is close to the expected performance.

On Risk and Time Pressure: When to Think and When to Do

no code implementations14 Nov 2021 Christoph Carnehl, Johannes Schneider

We show that the agent may return to the initial idea after having left it in the past to explore alternatives.

The Wrong Kind of Information

no code implementations7 Nov 2021 Aditya Kuvalekar, João Ramos, Johannes Schneider

Agents, some with a bias, decide between undertaking a risky project and a safe alternative based on information about the project's efficiency.

Domain Transformer: Predicting Samples of Unseen, Future Domains

1 code implementation10 Jun 2021 Johannes Schneider

The data distribution commonly evolves over time leading to problems such as concept drift that often decrease classifier performance.

Creativity of Deep Learning: Conceptualization and Assessment

no code implementations3 Dec 2020 Marcus Basalla, Johannes Schneider, Jan vom Brocke

While the potential of deep learning (DL) for automating simple tasks is already well explored, recent research has started investigating the use of deep learning for creative design, both for complete artifact creation and supporting humans in the creation process.

Reflective-Net: Learning from Explanations

1 code implementation27 Nov 2020 Johannes Schneider, Michalis Vlachos

Humans possess a remarkable capability to make fast, intuitive decisions, but also to self-reflect, i. e., to explain to oneself, and to efficiently learn from explanations by others.
