WebThe simplest protocol for communication between hyperopt's optimization algorithms and your objective function, is that your objective function receives a valid point from the search space, and returns the floating-point loss (aka negative utility) associated with that point. from hyperopt import fmin, tpe, hp best = fmin (fn= lambda x: x ** 2 ... Web15 apr. 2024 · Hyperopt is a Python library that can optimize a function's value over complex spaces of inputs. For machine learning specifically, this means it can optimize a model's accuracy (loss, really) over a space of hyperparameters.
