Researchers have developed a novel two-stage framework to improve the accuracy of brain-computer interfaces (BCIs) for decoding continuous 3D motor imagery. This approach combines a CNN-LSTM model for initial trajectory prediction with a reinforcement learning (RL) agent that corrects residual errors offline. The CNN-LSTM--RL system demonstrated significant improvements, increasing the mean correlation coefficient from 0.5076 to 0.7181 in 2D and reducing Root Mean Square Error by over 40% in both 2D and virtual reality environments.
