A Pytorch Implementation for Compact Bilinear Pooling. Adapted from tensorflow_compact_bilinear_pooling

Prerequisites

Install pytorch_fft by

pip install pytorch_fft

Usage

from torch import nn
from torch.autograd import Variable
from CompactBilinearPooling import CompactBilinearPooling

bottom1 = Variable(torch.randn(128, 512, 14, 14)).cuda()
bottom2 = Variable(torch.randn(128, 512, 14, 14)).cuda()

layer = CompactBilinearPooling(512, 512, 8000)
layer.cuda()
layer.train()

out = layer(bottom1, bottom2)
