Implementation of Microsoft's [Hummingbird](https://github.com/microsoft/hummingbird) library for converting trained Decision Tree

models into tensor computations.

## How to Use

Implement the `DecisionTree` protocol for any data source you would like to compile. Then you can use `Mockingjay.convert/1`

to generate an `Nx.Defn` prediction function that makes inferences. The output of `convert` will be a function with the signature

`fn x -> predict(x)`. The three strategies are GEMM, TreeTraversal, and PerfectTree traversal. You can specify the strategy using the

`:strategy` option in `convert` or use a heuristic strategy by default. The heuristic used is generally:

* GEMM: Shallow Trees (<=3)

* PerfectTreeTraversal: Tall trees where depth <= 10

* TreeTraversal: Tall trees unfit for PTT (depth > 10)

## Installation

```elixir

def deps do

  [

    {:mockingjay, "~> 0.1"}

  ]

end

```
