Web– Proposed a speciﬁc SDP framework, ODNN using optimal hyper-parameters of deep neural network. The hyper-parameters tuning is performed using a grid search-based optimization technique in three stages to get better results. Such type of framework for SDP is the ﬁrst work to the best of our knowledge. WebThe selected hyper-parameter value is the one which achieves the highest average performance across the n-folds. Once you are satisfied with your algorithm, then you can test it on the testing set. If you go straight to the testing set then you are risking overfitting.
