Tastoids ⩐
A Temperate, Terse Algebra of Taste
Wait, What?
Tastoids & their Algebra… are like comparing ‘Apples’ to ‘Oranges’
- Write a bit more of an introduction here.
Give them a Taste
gleam add tastoids
import gleam/io
import tastoids.{like} as t
pub fn main() -> Nil {
io.println("Hello, Tastoids!\n")
let apples = like("apples") |> echo
// ↪ Tastoid(Taste("apples", 1.0), 1)
let oranges = like("oranges") |> echo
// ↪ Tastoid(Taste("oranges", 1.0), 1)
io.println("\n Blend into ...")
let tastes = t.blend(apples, oranges) |> echo
// ↪ Tastoid(Taste(... [#("apples", 1.0), #("oranges", -1.0)])), 2)
io.println("\n Squash to an average of ...")
t.squash(tastes) |> echo
// ↪ Tastoid(Tastes(dict.from_list([#("apples", 0.5), #("oranges", -0.5)])), 1)
io.println("\n Blend is also invertible! blend(blended, retract(oranges)) -> like(apples)!")
t.blend(tastes, t.retract(oranges)) |> echo
// ↪ Tastoid(Taste("apples", 1.0), 1)
io.println(
"\n\n'Blue Blue Brown Blue' |> split(' ') |> map(like) |> reduce(t.blend) ",
)
io.print("↪ ")
let _ =
"Blue Blue Brown Blue"
|> string.split(" ")
|> list.map(fn(word) { like(word) })
|> list.reduce(t.blend)
|> echo
io.println("\n Have fun!")
}

Development
gleam run # Run the project
gleam test # Run the tests
Benchmark
While not my priority, it will be helpful to see how differeing implementations change performance (and its characteristics). To run the benchmarks, use the command:
gleam run -m bench
$ gleam run -m bench

TODO
-
Write a euclidian and cosine distance fn.
- _See
tastoids/{length,distance}
,tastoids.taste.{length,condense}
- _See
- Demonstrate how Tastoids + a vector db and iterative voting yield a form of simulated annealing towards the ‘true’ sentiment I was trying to express by voting things up/down.
As a Matter of Taste
TBD, general motivation, goals, and why this library will be unabashedly strange
