ASCENDS: Advanced data SCiENce toolkit for Non-Data Scientists
ASCENDS graphics user interface (left) correlation analysis between input and output/target of spreadsheet data (e.g., excel and csv) and (right) train surrogate machine learning models for rapid prediction. Regular alloy designers without computer science background can easily use this tool to analyze their own dataset.


Success stories of AI and machine learning have been motivating scientists who study physics, chemistry, materials, medicine, and many other subjects, to explore a new pathway of utilizing machine learning techniques like regression and classification for their scientific activities. However, most existing machine learning tools, systems, and methodologies have been developed for programming experts but not for scientists who have no or little knowledge of programming. A multidisciplinary team of researchers from Oak Ridge National Laboratory (ORNL) developed an advanced toolkit named ASCENDS to assist scientists or any persons who want to use their data for machine learning. ASCENDS provides a set of simple but powerful CLI (Command Line Interface) and GUI (Graphic User Interface) tools for non-data scientists to be able to intuitively perform advanced data analysis and machine learning techniques. The code can run on any personal computers, as well as modern supercomputers, such as ORNL’s Summit. The team launched the software as an open-source project[1] and published two journal papers in Journal of Open Source Software and Calphad.

Research Details

  • ASCENDS supports various classification/regression techniques (Linear regression, logistic regression, random forest, support vector machine, neural network, etc.)
  • ASCENDS supports feature selection based on various correlation metrics
  • ASCENDS is built on top of open source projects (Keras, TensorFlow, scikit-learn, etc.)
  • Although ASCENDS has been originally developed for the VTO Propulsion Materials Program to support material scientists' research on high-temperature alloy design, the tool can be also used for many other applications.

Citation and DOI


The VTO Propulsion Materials Program at ORNL has developed a powerful and versatile data analytics front-end tool for non-data scientists within the VTO project entitled “Machine Learning and Supercomputing to Predict Corrosion/Oxidation of High-Performance Valve Alloys.” The code greatly facilitates the analysis of alloy data, trains surrogate models, identifies correlations, and makes predictions to assist with the design of future experiments/simulations. Currently, available data analytics tools require a certain level of programming skill, which hampers the broader application of this emerging technique. ORNL developed the easy-to-use ASCENDS toolkit, which can help to analyze the datasets of many different disciplines, e.g., materials, physics, chemistry, and bioscience, to generate hypotheses and to develop AI/machine learning models for rapid/accurate prediction.
