Population Based Training (PBT) is an efficient hyperparameter optimization algorithm. PBT is a single-objective algorithm, but many real-world hyperparameter optimization problems involve two or more conflicting objectives. In this work, we therefore introduce a multi-objective version of PBT, MO-PBT. Our experiments on diverse multi-objective hyperparameter optimization problems (Precision/Recall, Accuracy/Fairness, Accuracy/Adversarial Robustness) show that MO-PBT outperforms random search, single-objective PBT, and the state-of-the-art multi-objective hyperparameter optimization algorithm MO-ASHA.

  1. Gradients: When Markets Meet Fine-tuning -- A Distributed Approach to Model Optimisation

    cs.AI 2025-06 reject novelty 6.0 of 10

    Gradients reports that competitive, reward-driven fine-tuning beats centralized AutoML in 82 to 100 percent of comparisons, but its evaluation does not isolate competition from a much larger compute budget.
