  use Phpml\Classification\KNearestNeighbors;
  
  $samples = [[1, 3], [1, 4], [2, 4], [3, 1], [4, 1], [4, 2]];
  $labels  = ['a', 'a', 'a', 'b', 'b', 'b'];

Build

1. Clone this repo.

2. Decide tag name to use as a base image from:

   • arm32v6arm(ARMv7) amdlatest(default, x86_64)
   • [See available tags]

3. Build image specifing the base image tag.

   The below sample will build with the base image keinos/php8-jit:arm32v6 as myname/php8-ml:local.

   docker build --build-arg NAME_TAG_IMAGE=arm32v6 -t myname/php8-ml:local .
