hyperas - Keras + Hyperopt: A very simple wrapper for convenient hyperparameter optimization

•    Python

A 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.

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.

hyperparameters - Automatically tuning hyperparameters for deep learning

•    Python

##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.

GBM-tune - Tuning GBMs (hyperparameter tuning) and impact on out-of-sample predictions

•    HTML

The 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.

Hyperopt-Keras-CNN-CIFAR-100 - Auto-optimizing a neural net (and its architecture) on the CIFAR-100 dataset

•    Python

This 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.
