# Tsne
[](https://hexdocs.pm/tsne)
[](https://hex.pm/packages/tsne)
From Wikipedia: [t-distributed stochastic neighbor embedding](https://en.wikipedia.org/wiki/T-distributed_stochastic_neighbor_embedding) (t-SNE) is a statistical method for visualizing high-dimensional data by giving each datapoint a location in a two or three-dimensional map.
This is an extremely low effort set of bindings to the Rust [`bhtsne`](https://docs.rs/bhtsne/latest/bhtsne/) crate.
You might use it like this:
```elixir
Mix.install(
[
{:exla, "~> 0.5"},
{:nx, "~> 0.5"},
{:rustler, "~> 0.0"},
{:scholar, "~> 0.1"},
{:tsne, "~> 0.1"}
],
config: [
nx: [default_backend: EXLA.Backend]
]
)
# Generate some random data.
key = Nx.Random.key(42)
{data, _} = Nx.Random.normal(key, 0, 1, shape: {1000, 256}, type: :f32)
# If your data is has high dimensionality, it's recommended to bring things
# down a fair bit using PCA before using t-SNE.
principal_components = Scholar.Decomposition.PCA.fit_transform(data, num_components: 50)
principal_components
|> Nx.to_list() # `Tsne` expects a list of lists.
|> Tsne.barnes_hut()
```
## Installation
If [available in Hex](https://hex.pm/docs/publish), the package can be installed
by adding `tsne` to your list of dependencies in `mix.exs`:
```elixir
def deps do
[
{:tsne, "~> 0.1.0"}
]
end
```
Documentation can be generated with [ExDoc](https://github.com/elixir-lang/ex_doc)
and published on [HexDocs](https://hexdocs.pm). Once published, the docs can
