The provided class labels for the 3 test files are derived from precomputed features.
We only focus on the training and testing of the classifier: single layer feedforward neural network (SLFN) based on a recently proposed learning algorithm: Extreme Learning Machine (ELM). The simulation includes 4 steps:
1, Model Selection: The optimal number of hidden neurons of SLFN is estimated by train and validation set approach.
2, Training Phase: The weights and biases of SLFN are estimated by ELM using training data.
3, Testing Phase: The testing output vectors are derived by the trained SLFN for each testing data.
4, Output vector fusion and 8-smple combination: An averaging filter of 80-sample window is applied to the testing output vectors and followed by Vote strategy. Vote strategy is deployed to produce the class labels for each group of 8 averaged testing output vectors every 0.5 seconds.
