 Emulation requires significant expertise in machine learning as well as familiarity with a broad and evolving ecosystem of tools for model training and downstream tasks. This creates a barrier to entry for domain researchers whose focus is on the underlying scientific problem. AutoEmulate [@autoemulate] lowers the barrier to entry by automating the entire emulator construction process (training, evaluation, model selection, and hyperparameter tuning). This makes emulation accessible to non-specialists while also offering a reference set of cutting-edge emulators, from classical approaches (e.g. Gaussian Processes) to modern deep learning methods, enabling benchmarking for experienced users.
 
-AutoEmulate v1.0 introduces easy-to-use interfaces for common emulation tasks. By providing these within a single package, the package enables users to construct sequential workflows. For example, sensitivity analysis can be applied to narrow the parameter space to a few key variables before calibrating this reduced set against real world data.  AutoEmulate also supports direct integration of custom simulators and active learning, in which the tool adaptively selects informative simulations to run to improve emulator performance at minimal computational cost.

For instance, sensitivity analysis can be applied in order to narrow down the parameter space to the key variables. This allows the user to calibrate the much smaller reduced set to match the output of the model to real-world observations.

 AutoEmulate was originally built on scikit-learn, which is well suited for traditional machine learning but less flexible for complex workflows. Version 1.0 introduces a PyTorch [@pytorch] backend that provides GPU acceleration for faster training and inference and automatic differentiation via PyTorch’s autograd system. It also makes AutoEmulate easy to integrate with other PyTorch-based tools. For example, the PyTorch refactor enables fast Bayesian model calibration using gradient-based inference methods such as Hamiltonian Monte Carlo exposed through Pyro [@pyro].
