is a competition in IJCAI’23. It is being organized by the Robotics Innovation Centre at the German Research Centre for Artificial Intelligence (DFKI) and the Department of Medical Technology Systems at the University of Duisburg-Essen. The goal of the competition
is to develop competitive Signal Processing and Machine Learning approaches for the asynchronous detection of erroneous behaviors based on single-trial EEG analysis.

<div style="margin:0px" class="ContentPasted0"><u class="ContentPasted0">Experimental Setup</u>:</div>
<div style="margin:0px" class="ContentPasted0">The experimental setup consisted of 4 main parts – a 64-channel EEG system, an eight-channel EMG system, an active orthosis device fitted on the right arm, and an air-filled ball held in the left hand of the subject.
The active orthosis provided support at the elbow joint to perform flexion-extension movements. During the experiment, the subjects performed 30 movement trials (15 flexions and 15 extensions). In each trial, the subjects indicated their intention to start
the movement by applying an initial force after which the active orthosis device took over the control of the movement. Additionally, out of the 30 trials, 6 were randomly selected during each of which an error was deliberately introduced. This error lasted
for a short duration of 250 ms and was characterized by a momentary change in the direction of movement. As soon as the subjects felt the errors, they were instructed to squeeze the ball in their left hand.</div>

<div style="margin:0px" class="ContentPasted0"><u class="ContentPasted0">Competition</u>:</div>
<div style="margin:0px" class="ContentPasted0">The competition is divided into 2 stages – Offline stage and online stage.</div>
<div style="margin:0px"><br class="ContentPasted0">
</div>
<div style="margin:0px" class="ContentPasted0"><u class="ContentPasted0">Offline Stage</u>:</div>
<div style="margin:0px" class="ContentPasted0">In the offline stage, pre-recorded EEG dataset is provided. This dataset is divided into labeled training data and unlabeled test data. The task for this stage is to train the machine learning model to detect the
deliberately introduced errors and perform a 10-fold cross-validation on the labeled training data. Furthermore, it is expected to test this model on the provided unlabeled test data and detect the exact time points where the errors were introduced.</div>

<div style="margin:0px" class="ContentPasted0"><u class="ContentPasted0">Online Stage</u>:</div>
<div style="margin:0px" class="ContentPasted0">The top 10 teams with the best results in the offline stage will be selected for the online stage of the competition wherein the teams would get an opportunity to test their approaches on our experimental setup
in real-time.</div>
