Examples of POCA in a sentence
In addition, the current TPE utilized by POCA does not account for the noise caused by evaluating configurations to different budgets.
We give as input the total POCA budget T (T = 600 in Figure 2b), a minimum configuration budget bmin (bmin = 1 in Figure 2b), a maximum configuration budget bmax (bmax = 8 in Figure 2b), and a promotion rate η (η = 0.5 in Figure 2b) defined as the proportion of configurations that will be promoted to a larger budget at each halving pointwithin a SH bracket.Iteratively, hyperband HBk will schedule NSHk successive halving brackets, each with index s j,k, j =1, .
This allows POCA to test 138 configurations total, by training less configurations to the maximum number of epochs.
Once training with any configuration completes, report its test accuracy to the TPE to update the TPE.Figure 1: POCA flowchart.
POCA allocates a reduced budget to the poor configurations that are likely at the outset, thereby saving resources to explore the more promising configurations found by the Bayesian model when more data becomes available.
