Background:

Electroencephalogram (EEG) offers a valuable, non-invasive method for monitoring brain activity, crucial for brain-computer interfaces.
The low spatial resolution of EEG presents a significant challenge for accurately decoding complex brain signals.
Existing methods for EEG-based brain activity decoding often struggle with precision due to inherent signal limitations.

Purpose of the Study:

To develop and validate a novel hybrid algorithm for decoding human brain activity from EEG signals.
To enhance the accuracy of predicting brain activity associated with visual stimuli (images).
To compare the performance of the proposed algorithm against established EEG analysis techniques.

Main Methods:

A hybrid algorithm combining a modified convolutional neural network for feature extraction, t-test for feature selection, and likelihood ratio-based score fusion for prediction.
Utilized multichannel EEG time-series data, applying multivariate pattern analysis principles.
Evaluated the algorithm on data from 30 participants, comparing results with the wavelet transform-support vector machine method.

Main Results:

The proposed hybrid algorithm achieved a prediction accuracy of 79.9% for novel data.
This represents a significant improvement over the currently popular wavelet transform-support vector machine method, which achieved 65.7% accuracy.
Demonstrated superior performance in decoding brain activity compared to existing recognized techniques.

Conclusions:

The novel hybrid algorithm significantly outperforms current methods in EEG-based brain activity decoding.
The developed approach offers a more accurate and reliable way to interpret brain signals for applications like brain-computer interfaces.
This advancement addresses the challenges posed by EEG's low spatial resolution, paving the way for more effective brain-computer interaction systems.
