The effects of hyperparameters (network topology, learning rate, activation function, and training function), transformation function and optimization algorithm on prediction performance and training time are systematically explored. The results indicate that training time increases with the number of hidden...
These actions were informed by the experimental design’s focus on hyper-parameter optimization through grid search (Supplementary Fig. S8). Learning information using the ESM-1b transformer To allow evolutionary diversity of natural sequences, we leveraged the pre-trained model ESM-1b transformer31...
Hyperparameter optimization for convolutional model Architecture design parameters were selected randomly rather than combinatorically as in a traditional grid search to enable a broader search of the architecture landscape within time and computation constraints70. The convolutional hyperparameters were varied...
Note that these results are obtained using a neural network for which hyper-parameter optimization have not been performed. Performance of the algorithm is expected to increase with optimized hyper-parameters. On the other hand, with respect to Dambros et al. (2019c), the work had been carried...
The gradient of the function is 1 for $ x \gt 0 $ while it is $ \alpha * e^x $ for $ x \lt 0 $. The function saturates for negative values to a value of $ - \alpha $. \alpha is a hyperparameter that is normally chosen to be 1. ...

where \({\theta _i}\) is an element in the hyperparameter set \(\theta\). The joint prior distribution of test and predicted values is denoted as follows: $$\left[ \begin{gathered} y \hfill \\ {y^*} \hfill \\ \end{gathered} \right]\sim N\left( {0,\left[ \begin{gathered...
Parameter settings of ACO: This ACO version is specially developed for continuous optimization [7] and the traditional parameters of ACO can be set the same as recommended in [7]. • Parameter settings of CMA-ES: CMA-ES is a successful evolutionary strategy (ES) variant using the covariance...
