- Hyperparameter OptimizationRun an automated, disciplined hyperparameter-search loop to improve a deep learning or LLM model against a chosen metric — define the search space and selection metric before looking at results, delegate trials, track them against a baseline, and verify the winning configuration before claiming an improvement. Use when the task is "improve/tune this model's hyperparameters," not for a single one-off training run.Votes: 0GitHub stars: 2
