WebMay 23, 2024 · FLANN and the proposed RVFLNN-CPSO algorithm in the identification of the nonlinear system have been made in Fig. 8. As expected, the proposed model has a faster response in system identification than the existing FLANN system. WebFLANN is a library for performing fast approximate nearest neighbor searches in high dimensional spaces. It contains a collection of algorithms we found to work best for nearest neighbor search and a system for automatically choosing the best algorithm and optimum parameters depending on the dataset.
