A Conversational Brain-Artificial Intelligence Interface

1 code implementation22 Feb 2024 Anja Meunier, Michal Robert Žák, Lucas Munz, Sofiya Garkot, Manuel Eder, Jiachen Xu, Moritz Grosse-Wentrup

We introduce Brain-Artificial Intelligence Interfaces (BAIs) as a new class of Brain-Computer Interfaces (BCIs).

Improvement-Focused Causal Recourse (ICR)

1 code implementation27 Oct 2022 Gunnar König, Timo Freiesleben, Moritz Grosse-Wentrup

We demonstrate that given correct causal knowledge, ICR, in contrast to existing approaches, guides towards both acceptance and improvement.

A Causal Perspective on Meaningful and Robust Algorithmic Recourse

no code implementations16 Jul 2021 Gunnar König, Timo Freiesleben, Moritz Grosse-Wentrup

Thus, an action that changes the prediction in the desired way may not lead to an improvement of the underlying target.

Decomposition of Global Feature Importance into Direct and Associative Components (DEDACT)

1 code implementation15 Jun 2021 Gunnar König, Timo Freiesleben, Bernd Bischl, Giuseppe Casalicchio, Moritz Grosse-Wentrup

Direct importance provides causal insight into the model's mechanism, yet it fails to expose the leakage of information from associated but not directly used variables.

A Distance Covariance-based Kernel for Nonlinear Causal Clustering in Heterogeneous Populations

no code implementations7 Jun 2021 Alex Markham, Richeek Das, Moritz Grosse-Wentrup

Even stronger, we prove that the kernel space is isometric to the space of causal ancestral graphs, so that distance between samples in the kernel space is guaranteed to correspond to distance between their generating causal structures.

A Distance Correlation-based Kernel for Nonlinear Causal Clustering in Heterogeneous Populations

no code implementations NeurIPS 2021 Alex Markham, Moritz Grosse-Wentrup

We consider the problem of causal structure learning in the setting of heterogeneous populations, i. e., populations in which a single causal structure does not adequately represent all population members, as is common in biological and social sciences.

Clustering

Relative Feature Importance

2 code implementations16 Jul 2020 Gunnar König, Christoph Molnar, Bernd Bischl, Moritz Grosse-Wentrup

Interpretable Machine Learning (IML) methods are used to gain insight into the relevance of a feature of interest for the performance of a model.

General Pitfalls of Model-Agnostic Interpretation Methods for Machine Learning Models

1 code implementation8 Jul 2020 Christoph Molnar, Gunnar König, Julia Herbinger, Timo Freiesleben, Susanne Dandl, Christian A. Scholbeck, Giuseppe Casalicchio, Moritz Grosse-Wentrup, Bernd Bischl

An increasing number of model-agnostic interpretation techniques for machine learning (ML) models such as partial dependence plots (PDP), permutation feature importance (PFI) and Shapley values provide insightful model interpretations, but can lead to wrong conclusions if applied incorrectly.

MYND: Unsupervised Evaluation of Novel BCI Control Strategies on Consumer Hardware

1 code implementation26 Feb 2020 Matthias R. Hohmann, Lisa Konieczny, Michelle Hackl, Brian Wirth, Talha Zaman, Raffi Enficiaud, Moritz Grosse-Wentrup, Bernhard Schölkopf

We introduce MYND: A framework that couples consumer-grade recording hardware with an easy-to-use application for the unsupervised evaluation of BCI control strategies.

Measurement Dependence Inducing Latent Causal Models

no code implementations19 Oct 2019 Alex Markham, Moritz Grosse-Wentrup

We consider the task of causal structure learning over measurement dependence inducing latent (MeDIL) causal models.

A note on the expected minimum error probability in equientropic channels

no code implementations23 May 2016 Sebastian Weichwald, Tatiana Fomina, Bernhard Schölkopf, Moritz Grosse-Wentrup

While the channel capacity reflects a theoretical upper bound on the achievable information transmission rate in the limit of infinitely many bits, it does not characterise the information transfer of a given encoding routine with finitely many bits.

Causal and anti-causal learning in pattern recognition for neuroimaging

no code implementations15 Dec 2015 Sebastian Weichwald, Bernhard Schölkopf, Tonio Ball, Moritz Grosse-Wentrup

Pattern recognition in neuroimaging distinguishes between two types of models: encoding- and decoding models.

Causal Inference

Decoding index finger position from EEG using random forests

no code implementations14 Dec 2015 Sebastian Weichwald, Timm Meyer, Bernhard Schölkopf, Tonio Ball, Moritz Grosse-Wentrup

While invasively recorded brain activity is known to provide detailed information on motor commands, it is an open question at what level of detail information about positions of body parts can be decoded from non-invasively acquired signals.

MERLiN: Mixture Effect Recovery in Linear Networks

1 code implementation3 Dec 2015 Sebastian Weichwald, Moritz Grosse-Wentrup, Arthur Gretton

Causal inference concerns the identification of cause-effect relationships between variables, e. g. establishing whether a stimulus affects activity in a certain brain region.

Causal interpretation rules for encoding and decoding models in neuroimaging

no code implementations15 Nov 2015 Sebastian Weichwald, Timm Meyer, Ozan Özdenizci, Bernhard Schölkopf, Tonio Ball, Moritz Grosse-Wentrup

Causal terminology is often introduced in the interpretation of encoding and decoding models trained on neuroimaging data.

Quantifying causal influences

no code implementations29 Mar 2012 Dominik Janzing, David Balduzzi, Moritz Grosse-Wentrup, Bernhard Schölkopf

Here we propose a set of natural, intuitive postulates that a measure of causal strength should satisfy.

Understanding Brain Connectivity Patterns during Motor Imagery for Brain-Computer Interfacing

no code implementations NeurIPS 2008 Moritz Grosse-Wentrup

EEG connectivity measures could provide a new type of feature space for inferring a subject's intention in Brain-Computer Interfaces (BCIs).
