Light Recurrent Unit

Light Recurrent Unit - Pytorch

Implementation of the Light Recurrent Unit in Pytorch

Install

$ pip install light-recurrent-unit-pytorch

Usage

import torch
from light_recurrent_unit_pytorch import LightRecurrentUnitCell

cell = LightRecurrentUnitCell(256)

x = torch.randn(2, 256)
hidden = torch.randn(2, 256)

next_hidden = cell(x, hidden) # (2, 256)

Single layer

import torch
from light_recurrent_unit_pytorch import LightRecurrentUnitLayer

layer = LightRecurrentUnitLayer(256)

x = torch.randn(2, 1024, 256)

out = layer(x) # (2, 1024, 256)

assert out.shape == x.shape

Stacked

import torch
from light_recurrent_unit_pytorch import LightRecurrentUnit

lru = LightRecurrentUnit(256, depth = 4)

x = torch.randn(2, 1024, 256)

out, layer_hiddens = lru(x) # (2, 1024, 256), List[(2, 256)]

assert out.shape == x.shape
