Splet21. mar. 2024 · PBT is already a population based method, where it will pause and pick the most promising off-spring to continue training. When a trial is restored for continued training, it will try to restore the latest checkpoint when it was stopped last time.

"Splet30. mar. 2024 · Hi @Kai_Yun,. for tune.qrandint - this sampler is used for the initial sampling of hyperparameter values. In population based training, hyperparameters are mutated when a trial exploits another trial - and per the original paper this means that the parameter values are multiplied with 0.8 or 1.2.

Among those 6, two stopped training after 600 iterations, another two also stopped training after 800 iterations. The remaining two are currently training. Spletmethod based on population based training (PBT) (Jader-berg et al. 2024). We can then perform hyperparameter ad-justment while the AlphaZero algorithm trains, saving pre-cious computing resources. Another signiﬁcant advantage of using PBT is that this method requires a single run only while incurring a small additional cost for the optimization
