When a data point is provided to the algorithm, with a given value of K, it searches for the K nearest neighbors to that data point. The nearest neighbors are found by calculating the distance between the given data point and the data points in the initial dataset.
WebThe traditional way of performing hyperparameter optimization has been grid search, or a parameter sweep, which is simply an exhaustive searching through a manually specified subset of the hyperparameter space of a learning algorithm. WebThe gain margin corresponding to the optimal point is about 4.57 dB. According to the proposed design method, the optimal parameters and the associated dynamic indices are listed in Table 1.
