Cellular Automata - School of Haskell | School of Haskell
This post shows how we can render automata on the web using a number of reusable components from the Haskell ecosystem. In this part we'll explore how to make extensible folds for hashing, explore the connection between Gabriel Gonzales' `foldl` library and Moore machines, discover a Comonad, and concoct a way to generate custom PNGs by leveraging pieces of the existing Haskell ecosystem.
jaspervdj - Image Processing with Comonads
A simple real-world example showing an image-processing Comonad Published on November 27, 2014 under the tag haskell Introduction A Comonad is a structure from category theory dual to Monad. Comonads are well-suited for image processing – Pretty much everyone on the internet Whenever Comonads come up, people usually mention the canonical example of evaluating cellular automata. Because many image
Comonads in Haskell
Comonads are the category-theoretic dual of monads. While monads have been found to be a very useful design pattern for structuring programs in functional languages, such as Haskell, comonads have so far failed to gain much traction. In this talk we will look at what comonads are and how they are defined in Haskell, comparing them with the Haskell definition of monads. We will then look at some sp
