Example usage of Coordinate Encoder

I used the CoordinateEncoder directly when processing XYZ points from Minecraft here.

Model params:

htm-community/mine-hack/blob/master/python/model_params/model_params.py#L51-L59


'encoders': {
    u'vector':    {
        'fieldname': u'vector',
        'n': 2048,
        'w': 51,
        'name': u'vector',
        'type': 'CoordinateEncoder'
    },
},

Code:

github.com

htm-community/mine-hack/blob/master/python/nupic_client.py#L69-L79


location, time = tuple(row.split(" "))
time = int(time)
xyz = [float(n) for n in location.split(",")]
vector = np.array(xyz).astype(int)
this_point = dict(time=time, location=xyz)
radius = calculate_radius(last_point, this_point)
last_point = this_point
modelInput = {
  "vector": (vector, radius)
}
result = model.run(modelInput)

If you don’t have a Z component, you can just use zero.
