To effectively solve the hyper-parameter setting problem, the present study proposes a framework for tuning the hyper-parameters of feed forward neural network (FFNN) and gene expression programming (GEP) with particle swarm optimization (PSO). Thereafter, the PSO coupled hybrid feed forward neural ...

The hyperparameter setting is the number of hidden layers of the neural network. The objective is the prediction accuracy, prediction error, or loss on a hold-out dataset obtained at the end of training. For automated hyperparameter optimization we also need hyperparameter ranges, a results ...
Disconnect between visualization and settings: My hypotheses often involve varying a hyperparameter and seeing its effect on quantities such as the loss, percentage of activations, etc. But the graphs don't have a legend that tells me which the setting each run used. As a result, I am forced...
Deep neural networks (DNN) have gained remarkable success on many rainfall predictions tasks in recent years. However, the performance of DNN highly relies upon the hyperparameter setting. In order to design DNNs with the best performance, extensive expertise in both the DNN and the problem domain...
With eight evaluations we get a fairly good idea what the score function looks like for this problem. Potentially 1 is the best solution, otherwise steeply falling. The best hyper-parameter setting in this case is eight. You can see that the search explores all values ofmin_samples_leafwith...
Another important HPO approach is the decision-theoretic method, where the algorithm obtains the hyper-parameter setting by searching the hyper-parameter space directly following some particular strategy. As examples, we have grid search, which uses brute force, and the simple and effective random sea...
