Welcome!

This is Slycat™ - a web-based data science analysis and visualization platform, created at Sandia National Laboratories.

Slycat™ is a web-based system for analysis of large, high-dimensional data, developed to provide a collaborative platform for remote analysis of data ensembles. An ensemble is a collection of data sets, typically produced through a series of related simulation runs. More generally, an ensemble is a set of samples, each consisting of the same set of variables, over a shared high-dimensional space describing a particular problem domain. Ensemble analysis is a form of meta-analysis that looks at the combined behaviors and features of a group of simulations in an effort to understand and describe the underlying domain space. For instance, sensitivity analysis uses ensembles to examine how simulation input parameters and simulation results are correlated. By looking at groups of runs as a whole, higher level patterns can be seen despite variations in the individual runs.

The Slycat™ system integrates data management, scalable analysis, and visualization via commodity web clients using a multi-tiered hierarchy of computation and data storage. Analysis models are computed local or on the Slycat™ server, and model artifacts are stored in a project database. These artifacts are the basis for visualizations that are delivered to users’ desktops through ordinary web browsers. Slycat™ currently provides two types of analysis: canonical correlation analysis (CCA) to model relationships between inputs and output metrics, and time series analysis featuring clustering and comparative visualization of waveforms. :ref:`install-slycat` to try it for yourself!

Design

Slycat™ incorporates several components:

  • A Web Server that can load, transform, index, and analyze moderate amounts of data, storing the analysis results for later visualization.
  • A web-based user interface that you use to pull your data into the Slycat™ Web Server, compute analyses, and view analysis results. You can use Slycat™ with any modern, standards-compliant browser, including Firefox, Safari, and Chrome. There is no software to install on your workstation.
  • A collection of command-line clients that can be used to push data into Slycat™ Web Server and control it remotely, if that suits your workflow better.

The Slycat™ Web Server provides easy collaboration and a graphical user interface for analyses that have broad appeal.
