Can Fairness be Automated? Guidelines and Opportunities for Fairness-aware AutoML

no code implementations15 Mar 2023 Hilde Weerts, Florian Pfisterer, Matthias Feurer, Katharina Eggensperger, Edward Bergman, Noor Awad, Joaquin Vanschoren, Mykola Pechenizkiy, Bernd Bischl, Frank Hutter

The field of automated machine learning (AutoML) introduces techniques that automate parts of the development of machine learning (ML) systems, accelerating the process and reducing barriers for novices.

Mind the Gap: Measuring Generalization Performance Across Multiple Objectives

1 code implementation8 Dec 2022 Matthias Feurer, Katharina Eggensperger, Edward Bergman, Florian Pfisterer, Bernd Bischl, Frank Hutter

Modern machine learning models are often constructed taking into account multiple objectives, e. g., minimizing inference time while also maximizing accuracy.

TabPFN: A Transformer That Solves Small Tabular Classification Problems in a Second

6 code implementations5 Jul 2022 Noah Hollmann, Samuel Müller, Katharina Eggensperger, Frank Hutter

We present TabPFN, a trained Transformer that can do supervised classification for small tabular datasets in less than a second, needs no hyperparameter tuning and is competitive with state-of-the-art classification methods.

Neural Model-based Optimization with Right-Censored Observations

no code implementations29 Sep 2020 Katharina Eggensperger, Kai Haase, Philipp Müller, Marius Lindauer, Frank Hutter

When fitting a regression model to predict the distribution of the outcomes, we cannot simply drop these right-censored observations, but need to properly model them.

BOAH: A Tool Suite for Multi-Fidelity Bayesian Optimization & Analysis of Hyperparameters

1 code implementation16 Aug 2019 Marius Lindauer, Katharina Eggensperger, Matthias Feurer, André Biedenkapp, Joshua Marben, Philipp Müller, Frank Hutter

Hyperparameter optimization and neural architecture search can become prohibitively expensive for regular black-box Bayesian optimization because the training and evaluation of a single model can easily take several hours.

Neural Networks for Predicting Algorithm Runtime Distributions

no code implementations22 Sep 2017 Katharina Eggensperger, Marius Lindauer, Frank Hutter

Many state-of-the-art algorithms for solving hard combinatorial problems in artificial intelligence (AI) include elements of stochasticity that lead to high variations in runtime, even for a fixed problem instance.

Deep learning with convolutional neural networks for decoding and visualization of EEG pathology

2 code implementations26 Aug 2017 Robin Tibor Schirrmeister, Lukas Gemein, Katharina Eggensperger, Frank Hutter, Tonio Ball

We apply convolutional neural networks (ConvNets) to the task of distinguishing pathological from normal EEG recordings in the Temple University Hospital EEG Abnormal Corpus.

Pitfalls and Best Practices in Algorithm Configuration

2 code implementations17 May 2017 Katharina Eggensperger, Marius Lindauer, Frank Hutter

Good parameter settings are crucial to achieve high performance in many areas of artificial intelligence (AI), such as propositional satisfiability solving, AI planning, scheduling, and machine learning (in particular deep learning).

Efficient Benchmarking of Algorithm Configuration Procedures via Model-Based Surrogates

no code implementations30 Mar 2017 Katharina Eggensperger, Marius Lindauer, Holger H. Hoos, Frank Hutter, Kevin Leyton-Brown

In our experiments, we construct and evaluate surrogate benchmarks for hyperparameter optimization as well as for AC problems that involve performance optimization of solvers for hard combinatorial problems, drawing training data from the runs of existing AC procedures.
