The PhD student Jan Sosulski won the Best Poster Award at the 8th international Graz BCI conference on September 20, 2019. He is currently working at Dr Michael Tangermann's Brain State Decoding Lab (Dept of Computer Science).
He presented the results of his paper "Spatial Filters for Auditory Evoked Potentials Transfer between Different Experimental Conditions". These data-driven spatial filters can be used to improve the performance of brain-computer interfaces based on event-related potentials (ERPs). However, as these filters are data-driven, they need to be calculated from scratch for each new subject. So far, it was unclear whether a new filter needs to be trained as well when the subject performs experiments under different conditions.
In his work (https://doi.org/10.3217/978-3-85125-682-6-50), Jan Sosulski could show when exactly the same filter can be applied to different experimental conditions. These results can lead to shorter BCI experiments in the future, as the time extensive filter training step can be shortened.
