Attention on Attention - Pytorch

Attention on Attention Implementation

This is a practice implementation after randomly finding it on Lucidrain's repo, I'm implementing the model architecture just for practice!

Basically the architecture is: x => q, k, v -> multihead attn with residual q -> concat -> 2 linear projects ->sigmoid -> mult -> add -> norm -> ffn -> add -> norm with residual of first add and norm

Install

pip3 install

Usage

AoA Module

import torch

from aoa.main import AoA

x = torch.randn(1, 10, 512)
model = AoA(512, 8, 64, 0.1)
out = model(x)
print(out.shape)

AoATransformer

import torch 
from aoa.main import AoATransformer


x = torch.randint(0, 100, (1, 10))
model = AoATransformer(512, 1, 100)
out = model(x)
print(out.shape)
