Query: Real-Time EEG Classification via Coresets for BCI Applications   A brain-computer interface (BCI) based on the motor imagery (MI) paradigm
translates one's motor intention into a control signal by classifying the
Electroencephalogram (EEG) signal of different tasks. However, most existing
systems either (i) use a high-quality algorithm to train the data off-line and
run only classification in real-time, since the off-line algorithm is too slow,
or (ii) use low-quality heuristics that are sufficiently fast for real-time
training but introduces relatively large classification error. In this work, we
propose a novel processing pipeline that allows real-time and parallel learning
of EEG signals using high-quality but possibly inefficient algorithms. This is
done by forging a link between BCI and core-sets, a technique that originated
in computational geometry for handling streaming data via data summarization.
  We suggest an algorithm that maintains the representation such coreset
tailored to handle the EEG signal which enables: (i) real time and continuous
computation of the Common Spatial Pattern (CSP) feature extraction method on a
coreset representation of the signal (instead on the signal itself) , (ii)
improvement of the CSP algorithm efficiency with provable guarantees by
applying CSP algorithm on the coreset, and (iii) real time addition of the data
trials (EEG data windows) to the coreset.
  For simplicity, we focus on the CSP algorithm, which is a classic algorithm.
Nevertheless, we expect that our coreset will be extended to other algorithms
in future papers. In the experimental results we show that our system can
indeed learn EEG signals in real-time for example a 64 channels setup with
hundreds of time samples per second. Full open source is provided to reproduce
the experiment and in the hope that it will be used and extended to more
coresets and BCI applications in the future.
