Is it normal to see oscillations in tested hyperparameters during bayesian optimisation?

I’ve been trying out bayesian hyperparameter optimisation (with TPE) on a simple CNN applied to the MNIST handwritten digit dataset. I noticed that over iterations of the optimisation loop, the tested parameters appear to oscillate slowly. Here’s the learning rate: Here’s the momentum: I won’t add a graph, but the batch size is also sampled…
