title: Asynchronous decoding of finger movements from ECoG signals using long-range dependencies conditional random fields.
abstract: In this work we propose the use of conditional random fields with long-range dependencies for the classification of finger movements from electrocorticographic recordings.
  
  
  
  The proposed method uses long-range dependencies taking into consideration time-lags between the brain activity and the execution of the motor task. In addition, the proposed method models the dynamics of the task executed by the subject and uses information about these dynamics as prior information during the classification stage.
  
  
  
  The results show that incorporating temporal information about the executed task as well as incorporating long-range dependencies between the brain signals and the labels effectively increases the system's classification performance compared to methods in the state of art.
  
  
  
  The method proposed in this work makes use of probabilistic graphical models to incorporate temporal information in the classification of finger movements from electrocorticographic recordings. The proposed method highlights the importance of including prior information about the task that the subjects execute. As the results show, the combination of these two features effectively produce a significant improvement of the system's classification performance.
