What Category Theory Teaches Us About DataFrames

The author analyzes the structure of dataframes and identifies three fundamental operations: Delta (restructuring), Sigma (merging), and Pi (pairing), which can be used to build a dataframe algebra. Category theory provides a framework for understanding these operations and their relationships, allowing for a more principled design of dataframe libraries.

Category Theory Illustrated – Types

https://abuseofnotation.github.io/category-theory-illustrated/06_type/zfc_pairing.svg
In this chapter we will talk about types. This might be disappointing for you, if you expected to learn about as many new categories as possible (which you don’t even suspect are really categories till the unexpected reveal)—we’ve been talking about the category of types in a given programming language ever since the first chapter, and we already know how they form a category. However, types ...
