Types

Impression

pub type Impression {
  Yum
  Yuck
  Meh
  Saw(worth: Float)
  Pass
}

Constructors

```
Yum
```
I liked it, +1
```
Yuck
```
I disliked it, -1
```
Meh
```
I saw it, and ignoring it is worth ~ -5%
```
Saw(worth: Float)
```
I saw it, ascribing scaling it by weight
```
Pass
```
I saw it, and have absolutely no impression

Tastoid

</>

A Tastoid (𝕥) is an element within a subset of Tastoids (𝕋), constrained to only interact with other tastoids of the same imbedding indices ( Imbedding(space)).

pub type Tastoid(of) {
  Tasteless
  Tastoid(taste: taste.Taste, cardinality: Int)
}

Constructors

```
Tasteless
```
The empty Tastoid (shared by all index-spaces)
```
Tastoid(taste: taste.Taste, cardinality: Int)
```
An impression (or aggregation) of taste e.g. Tastoid(t) -> Tastoids(t, 1)

Values

from

</>

pub fn from(thing name: String) -> Tastoid(String)

Coerce a thing of an into a Tastoid, assuming…

The thing’s type is the Imbedding(space) of the Tastoid
The sentiment of that thing is 1.0 ~ a count of its occurances

In effect, from(thing) is 1 of that thing, as a Tastoid

Example:

"from" |> tastoid.from -> Tastoid(Taste("from", 1.0"), k=1) 
42     |> tastoid.from -> Tastoid(Taste(42, 1.0), k=1)

from_dense_embedding

</>

pub fn from_dense_embedding(values: List(Float)) -> Tastoid(a)

Experimental: A (quiet) naive dense -> sparse mapper to facilitate experimentation (see test/playground/fruit.gleam)

from_impression

</>

pub fn from_impression(
  of thing: String,
  worth sentiment: Impression,
) -> Tastoid(String)

Given any index (string, Int, or `Set(index)``), coerce it into a simple Tastoid worth a single contribution (k=1)

from_sparse_embedding

</>

pub fn from_sparse_embedding(
  values: List(Float),
  by indices: List(Int),
) -> Tastoid(Int)

Coerce a sparse/dense embeddings pair of value and index lists into a conjugated Tastoid worth a single contribution (k=1)

from_taste

</>

pub fn from_taste(
  of taste: taste.Taste,
  worth impression: Impression,
) -> Tastoid(index)

A tasting of a taste and the impression thereof (e.g. a ‘weight’ or value-multiplier) yield a Tastoid of cardinality (k=1).
