Tabular is an Excel 2013 add-in that brings the power of machine learning to data enthusiasts — the large class of spreadsheet users who wish to model and learn from their data, who have some knowledge of probability distributions and data schemas, but who are not necessarily professional developers. Tabular helps the data enthusiast model and visualize their data. Tabular automatically suggests a model from the data schema, allows the enthusiast to edit and refine the model, infers model parameters from data and predicts missing values, and visualizes the results using Excel’s standard features. The ability to query for missing values provides a uniform interface to a wide variety of tasks, including classification, clustering, recommendation, and ranking. Tabular is based on probabilistic programming technology, which enables a wide range of machine learning algorithms to be constructed based on a probabilistic model. A unique feature is that Tabular models are simply succinct annotations on the relational schema of the Excel data model. Tabular provides a fast and fluid visual interface to the underlying Infer.NET inference engine.
