Traditional invasive methods have often achieved high performance in decoding. However, decoding using non-invasive methods like EEG is very challenging, especially for imagined speech, where understanding a user's intent through mere thoughts is particularly difficult. To address this, we developed a method that achieved high performance.

• Tech Stack: Python, PyTorch, NumPy, MATLAB, Pandas
• Features:
  • Achieved a high F1 score
  • Plan to further develop this method not only for decoding but also for language processing
  • It takes about 7 Hours for training.

This project investigates the use of advanced neural network models for predicting nonlinear time series data, specifically focusing on applications in BCI and financial markets.

• Tech Stack: Python, Scikit-learn, Pandas, Pytorch
• Features:
  • Optimized the hyperparameters of the ESN and the TA using a heuristic optimization technique, GA (Genetic Algorithm)
