WebJan 29, 2024 · Here’s a simple end-to-end example. First, we define a model-building function. It takes an hp argument from which you can sample hyperparameters, such as hp.Int('units', min_value=32, max_value=512, step=32) (an integer from a certain range). Notice how the hyperparameters can be defined inline with the model-building code.

WebOct 20, 2024 · Integer quantization is an optimization strategy that converts 32-bit floating-point numbers (such as weights and activation outputs) to the nearest 8-bit fixed-point numbers. This results in a smaller model and increased inferencing speed, which is valuable for low-power devices such as microcontrollers. WebThe scipy.optimize package provides several commonly used optimization algorithms. This module contains the following aspects − Unconstrained and constrained minimization of multivariate scalar functions (minimize ()) using a variety of algorithms (e.g. BFGS, Nelder-Mead simplex, Newton Conjugate Gradient, COBYLA or SLSQP)

Python comes with a lot of batteries included. You can writehigh-quality, efficient code, but it’s hard to beat the underlying libraries.
