You combine the predictions of smaller models and feed those into another model. However, in practice, implementing them can be a major headache. Xcessiv holds your hand through all the implementation details of creating and optimizing stacked ensembles so you're free to fully define only the things you care about.

automl scikit-learn automated-machine-learning hyperparameter-optimization hyperparameter-tuning hyperparameter-search bayesian-optimization metalearning meta-learning smacA very simple convenience wrapper around hyperopt for fast prototyping with keras models. Hyperas lets you use the power of hyperopt without having to learn the syntax of it. Instead, just define your keras model as you are used to, but use a simple template notation to define hyper-parameter ranges to tune. To do hyper-parameter optimization on this model, just wrap the parameters you want to optimize into double curly brackets and choose a distribution over which to run the algorithm.

hyperopt keras hyperparameter-optimizationauto_ml is designed for production. Here's an example that includes serializing and loading the trained model, then getting predictions on single dictionaries, roughly the process you'd likely follow to deploy the trained model. All of these projects are ready for production. These projects all have prediction time in the 1 millisecond range for a single prediction, and are able to be serialized to disk and loaded into a new environment after training.

The tool dispatches and runs trial jobs that generated by tuning algorithms to search the best neural architecture and/or hyper-parameters in different environments (e.g. local machine, remote servers and cloud). This command will start an experiment and a WebUI. The WebUI endpoint will be shown in the output of this command (for example, http://localhost:8080). Open this URL in your browser. You can analyze your experiment through WebUI, or browse trials' tensorboard.

Use defs.meta/defs_regression.meta to try many models in one Hyperband run. This is an automatic alternative to constructing search spaces with multiple models (like defs.rf_xt, or defs.polylearn_fm_pn) by hand.

It's framework agnostic and built on top of the python argparse API for ease of use. If you're a researcher, test-tube is highly encouraged as a way to post your paper's training logs to help add transparency and show others what you've tried that didn't work.

model-based-optimization r r-package optimization mlr hyperparameter-optimization black-box-optimization bayesian-optimization##Why Hyperparameter is controling how to learn the optimization algorithm. So it could directly effect the convergence performence as well as model precision. Given well tuned hyperparameters, even a simple model could be robust enough. Check the publication of "Bayesian Optimization of Text Representations". According to experiences, the optimization alogrithm is very sensitive to learning rate and regularization parameters. ##Idea Firstly, I deal with this problem from two individual spaces, one is the parameter, the other is the hyper-parameter. Learning could be consided as picking one point from the HPS(hyper parameters space) and then getting training result from the paramter space. How to map the two different spaces and pick an optimized point from HPS via the performance of parameter space? Researchers have found that reverse-mode differentiation proposed by Bengio(2000) in his paper "Gradient-based optimization of hyperpa-parameters" could resolve this issue. But there exists a big problem with RMD, it will consume thousands of times of memory to store the reverse path. To solve this problem the paper "Gradient-based Hyperparameter Optimization through Reversible Learning", which relies on momentum could reduce hunderds of times of memory compared with the origin RMD. Jie Fu's paper "DrMAD: Distilling Reverse-Mode Automatic Differentiation for Optimizing Hyperparameters of Deep Neural Networks" discards all training trajectories with zero memory consumption.

hyperparameter-optimization deep-learningTune the hyperparameters of your PyTorch models with HyperSearch. Keys are of the form {layer_num}_{hyperparameter} where layer_num can be a layer from your nn.Sequential model or all to signify all layers. Values are of the form [distribution, x] where distribution can be one of uniform, quniform, choice, etc.

hyperband hyperparameter-optimization pytorch deep-learning tuning-parametersMilano (Machine learning autotuner and network optimizer) is a tool for enabling machine learning researchers and practitioners to perform massive hyperparameters and architecture searches. Your script can use any framework of your choice, for example, TensorFlow, PyTorch, Microsoft Cognitive Toolkit etc. or no framework at all. Milano only requires minimal changes to what your script accepts via command line and what it returns to stdout.

deep-learning deep-neural-networks automl hyperparameter-tuning hyperparameter-optimization machine-learningA library for doing Bayesian Optimization using Gaussian Processes (blackbox optimizer) in Go/Golang. This project is under active development, if you find a bug, or anything that needs correction, please let me know.

bayesianoptimization bayesopt machine-learning hyperparameter-optimization optimization blackbox-optimizer gaussian-processesThis project acts as both a tutorial and a demo to using Hyperopt with Keras, TensorFlow and TensorBoard. Not only we try to find the best hyperparameters for the given hyperspace, but also we represent the neural network architecture as hyperparameters that can be tuned. This automates the process of searching for the best neural architecture configuration and hyperparameters. Here, we are meta-optimizing a neural net and its architecture on the CIFAR-100 dataset (100 fine labels), a computer vision task. This code could be easily transferred to another vision dataset or even to another machine learning task.

hyperopt hyperparameter-optimization hyperparameter-tuning hyperparameters-optimization hyperparameter-search keras cnn cnn-keras tensorflowThe goal of this repo is to study the impact of having one dataset/sample ("the dataset") when training and tuning machine learning models in practice (or in competitions) on the prediction accuracy on new data (that usually comes from a slightly different distribution due to non-stationarity). To keep things simple we focus on binary classification, use only one source dataset with mix of numeric and categorical features and no missing values, we don't perform feature engineering, tune only GBMs with lightgbm and random hyperparameter search (might also ensemble the best models later), and we use only AUC as a measure of accuracy.
