Scikit-learn is a great tool for ML and with Auto-Scklearn it has become even more amazing. Auto-Scklearn is created by the researchers at the University of Freiburg.
Built around the scikit-learn Machine Learning library, auto-sklearn automatically searches for the right learning algorithm for a new Machine Learning dataset and optimizes its hyperparameters.
Auto-sklearn provides out-of-the-box supervised Machine Learning. Preprocessing in auto-sklearn is divided into data preprocessing and feature preprocessing.
Auto-Scklearn does not focus on neural architecture search for deep neural networks but uses Bayesian optimization for hyperparameter tuning for “traditional” Machine Learning algorithms that are implemented within scikit-learn.
Auto-Keras is also a beautiful tool for AutoML. It is an open-source python package written in the very easy to use deep learning library Keras.
Auto-Keras mainly focuses to reduce the barrier to entry to performing Machine Learning and deep learning through the use of automated Neural Architecture Search (NAS) algorithms.
Auto-Keras provides functions to automatically search for architecture and hyperparameters of deep learning models. AutoKeras uses ENAS, an efficient and most recent version of Neural Architecture Search.
Auto-Keras utilizes the Neural Architecture Search but applies “network morphism” (keeping network functionality while changing the architecture) along with Bayesian optimization to guide the network morphism for more efficient neural network search.
With Auto-Keras, a programmer with minimal Machine Learning expertise can apply these algorithms to achieve state-of-the-art performance with very little effort.
TPOT is an open-source Python data science automation tool, which operates by optimizing a series of feature preprocessors and models, in order to maximize cross-validation accuracy on data sets.
TPOT is built on the scikit learn library and follows the scikit learn API closely. It can be used for regression and classification tasks and has special implementations for medical research.
TPOT has what its developers call a genetic search algorithm to find the best parameters and model ensembles. It could also be thought of as a natural selection or evolutionary algorithm.
TPOT tries a pipeline, evaluates its performance, and randomly changes parts of the pipeline in search of better-performing algorithms.

H2O’s core code is written in Java that enables the whole framework for multi-threading. Although it is written in Java, it provides interfaces for R, Python, and a few others, thus enabling it to be used efficiently.
AutoML provides APIs in Python and R that comes with H2O library.
H2O architecture can be divided into different layers in which the top layer will be different APIs, and the bottom layer will be H2O JVM.
H2O automated platform contains models that provide an initial test ride so that the user doesn’t have to know about the nitty-gritty details of building a model from scratch for autonomous driving.
Pytorch the library managed by Facebook has many important features for Machine Learning and Deep Learning, Auto Pytorch is one of those features that really helps to automate many time-consuming processes in ML.
Finding the right architecture and hyperparameter settings for training a deep neural network is crucial for achieving top performance.
Auto-PyTorch automates these two aspects by using multi-fidelity optimization and Bayesian optimization (BOHB) to search for the best settings.
The current version of Auto-PyTorch is an early alpha and only supports featured data. The upcoming versions will also support image data, natural language processing, speech, and videos.
Many different Machine Learning algorithms exist that can easily be used off the shelf, many of these methods are implemented in the open-source WEKA package.
However, each of these algorithms has its own hyperparameters that can drastically change their performance, and there are a staggeringly large number of possible alternatives overall.
Auto-WEKA considers the problem of simultaneously selecting a learning algorithm and setting its hyperparameters, going beyond previous methods that address these issues in isolation.
Auto-WEKA does this using a fully automated approach, leveraging recent innovations in Bayesian optimization and help non-expert users to more effectively identify Machine Learning algorithms and hyperparameter settings appropriate to their applications.
Our hope is that Auto-WEKA will help non-expert users to more effectively identify Machine Learning algorithms and hyperparameter settings appropriate to their applications, and hence to achieve improved performance.
