tech.ml.dataset Getting Started

What kind of data?

TMD processes tabular data, that is, data logically arranged in rows and columns. Similar to a spreadsheet (but handling much larger datasets) or a database (but much more convenient), TMD accelerates exploring, cleaning, and processing data tables. TMD inherits Clojure's data-orientation and flexible dynamic typing, without compromising on being functional; thereby extending the language's reach to new problems and domains.

tech.ml.dataset Walkthrough

tech.ml.dataset (TMD) is a Clojure library designed to ease working with tabular data, similar to data.table in R or Python's Pandas. TMD takes inspiration from the design of those tools, but does not aim to copy their functionality. Instead, TMD is a building block that increases Clojure's already considerable data processing power.

High Level Design

In TMD, a dataset is logically a map of column name to column data. Column data is typed (e.g., a column of 16 bit integers, or a column of 64 bit floating point numbers), similar to a database. Column names may be any Java object - keywords and strings are typical - and column values may be any Java primitive type, or type supported by tech.datatype, datetimes, or arbitrary objects. Column data is stored contiguously in JVM arrays, and missing values are indicated with bitsets.

This topic summarizes many of the most frequently used TMD functions, together with some quick notes about their use. Functions here are linked to further documentation, or their source. Note, unless a namespace is specified, each function is accessible via the tech.ml.dataset namespace.

For a more thorough treatment, the API docs list every available function.
