What is Glaucus?

Glaucus is a Data Flow based machine learning suite that incorporates Automated machine learning pipeline, Simplified the complex processes of machine learning algorithms and applying Excellent distributed data-processing engines. For the non-data science professionals across the domain, help them get the benefits of powerful machine learning tools by a simple way.

Our platform integrates many excellent data processing engines including Spark, Tensorflow, Scikit-learn, and we established a set of easy-to-use design process bases on them. The user only need to upload data, simple configuration, algorithm selection, and train the algorithm by automatic or manual parameter adjustment. The platform also provides a wealth of evaluation indicators for the training model, so that non-professionals can maximize the role of machine learning in their fields. The entire platform structure as shown below, the main functions are:

• Receive Multi-source dataset, including structured, document and image data;
• Provides rich mathematical statistics function, and the graphical interface allows users to easily grasp the data situation;
• In automatic mode, we implement full pipe automation from preprocessing, feature engineering to machine learning algorithms;
• In manual mode, it dramatically simplifies machine learning pipeline processes, and provides automated data cleaning, semi-automated feature selection, and depth learning suites.

The Technical Architecture of Glaucus

The system adopts the MVC framework, which is roughly divided into the reaction front end, Spring Boot+Flask business layer and Spark+Scikitlearn+Keras data engine layer, as shown in the figure below. The system is divided into four parts:

• The front end uses the framework of React+Redux, the design part uses Ant Design, and the diagram part uses Ant Design;
• The business layer primarily uses Spring Boot (Java) and Flask (Python) as RESTful interfaces;
• The data processing framework is mainly based on the distributed framework Spark, which extends the storage model using HDFS and MongoDB as the data persistence layer, and extends the runtime environment based on Docker and Linux virtual machines. The optimization of Shuffle operator is carried out in our Spark framework. The distributed server part mainly shows the deployment of Spark, Hadoop and MongoDB;
• The Data Engine part primarily uses distributed machine learning libraries: Spark ML and Tensorflow based Keras framework, automated machine learning mainly uses SMAC-based Bayesian optimizer pipe tuning Auto-sklearn and Deap-based Genetic Algorithm Superconducting Tuning TPOT.

Deploy Glaucus

Pull our project, enter /glaucus and there three folers: /java, /python, /web, deploy by the steps in QuckStart.md.

Use Glaucus

The following two examples demonstrate the use of the Glaucus platform in both manual mode and automatic mode.

1. Manual Mode

• First find the / data / test.csv file, enter our platform, click the upload file, the data will be automatically uploaded to the cloud server, and after that, system will automatically analyze your data;

• After uploading the files, you will see the system automatically analyze the fields, then users can click start analysis for a brief analysis of the file, or click add configuration button;
• After entering the configuration interface, the first step is to fill in and select the red box to complete the configuration, including configuration name, the main category of the model, and select training features;

• The second step is the adjustment of specific model and parameter, as shown in the red box below;

• Finally, after confirming all the information, start training;

• After training, you can view the training model results, the system will automatically save the user training results.

• Besides that, you can use the model you trained, click use model on the model page, you can upload your testing data, then your trained model will predict the target feature.

2. Automatic Mode

• Based on /data/test.csv, click the Add Configuration button again;

• After entering the configuration interface, select Automatic Classifier in the Select Model Category, and complete the automation model after completing the red box;

• After training you can view the results of the automated training model and the selected pipeline of the training model.
