Further, we propose a method of speeding up the search by using subsets of data. Results show that random search performs well compared to Bayesian methods and that a combined search can speed up the search by a factor of 5.Alexander Wendt...
The CBO algorithm is a derivative-free optimization method that uses a Bayesian optimization approach to explore the hyperparameter space. The optimization process is executed by calling the search.search method, which performs the evaluations of the run function with different configurations of the ...
Recommended Hyperparameter Search Method Below, hyperparameters and recommendations for their adjustment are provided. The proposed values are generally applicable to large language models built upon NeMo Megatron, such as BioNeMo models. Precision Configure with: trainer.precision=bf16-mixed if available...
We propose random search as a substitute and baseline that is both reasonably efficient (roughly equivalent to or better than combinining manual search and grid search, in our experiments) and keeping the advantages of implementation simplicity and reproducibility of pure grid search. … [R]andom ...

For machine learning algorithms, fine-tuning hyperparameters is a computational challenge due to the large size of the problem space. An efficient strategy for adjusting hyperparameters can be established with the use of the greedy search and Swarm intelligence algorithms. The Random Search and Grid...
from three hyperparameter tuning methods — grid search, random search, and Bayesian optimization. If evaluating our model with training data will be quick, we can choose the grid search method. Otherwise, we should select random search or Bayesian optimization to save time and computing resources...
