What it is

Orange Data Mining is open-source software for machine learning, data mining, and data visualization. It runs on Linux, macOS, and Windows, and is available for free under the GNU GPL 3.0 or later; add-ons may have additional licensing requirements. Users make analyses by connecting widgets for retrieving and preparing data, visualizing it, building models, and evaluating them. Interactive views include scatter plots, box plots, histograms, heat maps, MDS projections, and model-specific displays. The model catalog includes methods such as decision trees, random forests, support vector machines, neural networks, and logistic regression. Add-ons cover areas including text mining, network analysis, fairness, time series, and gene expression analysis. Data can come from spreadsheet and text files, Google Spreadsheets, and PostgreSQL or MSSQL databases; the SQL widget supports only PostgreSQL and MSSQL. Orange is installed locally and can work offline. Embedded widgets send data to a server for computation, though the FAQ says it is not stored there. Orange cannot export workflows as Python scripts and is not compatible with R.
