Getting started / The Keras ecosystem

The Keras ecosystem

The Keras project isn't limited to the core Keras API for building and training neural networks. It spans a wide range of related initiatives that cover every step of the machine learning workflow.


KerasHub

KerasHub Documentation - KerasHub GitHub repository

KerasHub is a natural language processing library that supports users through their entire development cycle. Our workflows are built from modular components that have state-of-the-art preset weights and architectures when used out-of-the-box and are easily customizable when more control is needed.


KerasTuner

KerasTuner Documentation - KerasTuner GitHub repository

KerasTuner is an easy-to-use, scalable hyperparameter optimization framework that solves the pain points of hyperparameter search. Easily configure your search space with a define-by-run syntax, then leverage one of the available search algorithms to find the best hyperparameter values for your models. KerasTuner comes with Bayesian Optimization, Hyperband, and Random Search algorithms built-in, and is also designed to be easy for researchers to extend in order to experiment with new search algorithms.


AutoKeras

AutoKeras Documentation - AutoKeras GitHub repository

AutoKeras is an AutoML system based on Keras. It is developed by DATA Lab at Texas A&M University. The goal of AutoKeras is to make machine learning accessible for everyone. It provides high-level end-to-end APIs such as ImageClassifier or TextClassifier to solve machine learning problems in a few lines, as well as flexible building blocks to perform architecture search.

import autokeras as ak

clf = ak.ImageClassifier()
clf.fit(x_train, y_train)
results = clf.predict(x_test)

BayesFlow

BayesFlow documentation - BayesFlow

A Python library for amortized Bayesian workflows using generative neural networks, built on Keras 3, featuring:

  • A user-friendly API for rapid Bayesian workflows
  • A rich collection of neural network architectures
  • Multi-backend support via Keras 3: You can use PyTorch, TensorFlow, or JAX
