چکیده

This paper discusses simulated on-line unsupervised adaptation of the LDA classifier in order to counteract the harmful effect of non-class related non-stationarities in EEG during BCI sessions. Three types of adaptation procedures were applied to the two large BCI data sets from TU Graz and Berlin BCI project. Our results demonstrate that the unsupervised adaptive classifiers can improve performance substantially under different BCI settings. More importantly, since label information is not necessary, they are applicable to wide ranges of practical BCI tasks.

EEG Based Brain Computer Interface Hand Grasp Control: Feature Extraction Method MTCSP

Brain-Computer Interfaces (BCIs) are communication systems, which enable users to send commands to computers by using brain activity only; this activity being generally measured by Electroencephalography (EEG). BCIs are generally designed according to a pattern recognition approach, i.e., by extracting features from EEG signals, and by using a classifier to identify the user’s mental state from...

Deep Unsupervised Domain Adaptation for Image Classification via Low Rank Representation Learning

Domain adaptation is a powerful technique given a wide amount of labeled data from similar attributes in different domains. In real-world applications, there is a huge number of data but almost more of them are unlabeled. It is effective in image classification where it is expensive and time-consuming to obtain adequate label data. We propose a novel method named DALRRL, which consists of deep ...

Combining Classifier Guided by Semi-Supervision

The article suggests an algorithm for regular classifier ensemble methodology. The proposed methodology is based on possibilistic aggregation to classify samples. The argued method optimizes an objective function that combines environment recognition, multi-criteria aggregation term and a learning term. The optimization aims at learning backgrounds as solid clusters in subspaces of the high...
