Machine Learning Optimized Orthogonal Basis Piecewise Polynomial Approximation

1 code implementation13 Mar 2024 Hannes Waclawek, Stefan Huber

We show that, using this regularization approach, Chebyshev basis performs better than power basis for all relevant optimizers in the combined approximation and continuity optimization setting and demonstrate usability of the presented approach within the electronic cam domain.

Topological Data Analysis in smart manufacturing processes -- A survey on the state of the art

no code implementations13 Oct 2023 Martin Uray, Barbara Giunti, Michael Kerber, Stefan Huber

Topological Data Analysis (TDA) is a mathematical method using techniques from topology for the analysis of complex, multi-dimensional data that has been widely and successfully applied in several fields such as medicine, material science, biology, and others.

Closing the Loop: Testing ChatGPT to Generate Model Explanations to Improve Human Labelling of Sponsored Content on Social Media

1 code implementation8 Jun 2023 Thales Bertaglia, Stefan Huber, Catalina Goanta, Gerasimos Spanakis, Adriana Iamnitchi

To improve annotation accuracy and, thus, the detection of sponsored content, we propose using chatGPT to augment the annotation process with phrases identified as relevant features and brief explanations.

An Architecture for Deploying Reinforcement Learning in Industrial Environments

no code implementations2 Jun 2023 Georg Schäfer, Reuf Kozlica, Stefan Wegenkittl, Stefan Huber

Industry 4. 0 is driven by demands like shorter time-to-market, mass customization of products, and batch size one production.

An OPC UA-based industrial Big Data architecture

no code implementations2 Jun 2023 Eduard Hirsch, Simon Hoher, Stefan Huber

It buffers and preprocesses the information for the purpose of harmonizing and providing a holistic state space of a factory, as well as mappings to the current state of a production site.

A Mini Review on the utilization of Reinforcement Learning with OPC UA

no code implementations24 May 2023 Simon Schindler, Martin Uray, Stefan Huber

However, since RL and OPC UA are from different fields, there is a need for researchers to bridge the gap between the two technologies.

$\mathcal{C}^k$-continuous Spline Approximation with TensorFlow Gradient Descent Optimizers

no code implementations22 Mar 2023 Stefan Huber, Hannes Waclawek

Our experiments show that the problem solution is feasible using TensorFlow gradient tapes and that AMSGrad and SGD show the best results among available TensorFlow optimizers.

Improvements for mlrose applied to the Traveling Salesperson Problem

no code implementations29 Sep 2021 Stefan Wintersteller, Martin Uray, Michael Lehenauer, Stefan Huber

In this paper we discuss the application of Artificial Intelligence (AI) to the exemplary industrial use case of the two-dimensional commissioning problem in a high-bay storage, which essentially can be phrased as an instance of Traveling Salesperson Problem (TSP).

Understanding Emails and Drafting Responses -- An Approach Using GPT-3

no code implementations5 Feb 2021 Jonas Thiergart, Stefan Huber, Thomas Übellacker

Providing computer systems with the ability to understand and generate natural language has long been a challenge of engineers.

Statistical Topological Data Analysis - A Kernel Perspective

no code implementations NeurIPS 2015 Roland Kwitt, Stefan Huber, Marc Niethammer, Weili Lin, Ulrich Bauer

We consider the problem of statistical computations with persistence diagrams, a summary representation of topological features in data.
