Pruning Multilayered ELM Using Cholesky Factorization and Givens Rotation Transformation

Figure 4

The average testing accuracy for the algorithm P-MELM with different hidden layers using (a) Diabetic Retinopathy Debrecen, (b) image segmentation, and (c) coal spectral data, while the hidden node is decreased one by one. Here, M and L are the number of hidden layers and the number of redundant nodes removed, respectively.
