Working with Fashion Models

Description

PyData London 2016

Since the dawn of time man has harnessed the power of convolutional neural networks to understand fashion. In this presentation, I carry on the trend and discuss how we've built a general purpose visual fashion representation by simultaneously training against multiple objectives with multiple images per objective. There will be lots of pictures.

Fashion is a visual medium so it makes sense for our models of fashion to include visual features. In this presentation, I'll describe how we've build a general purpose visual fashion representation using CNNs. The network is multi-task (multiple labels per image), multi-image (multiple images per label) and it runs on multiple GPUs. We used the python library Chainer to fit the network.

I'll visually explore what is going on inside the black box of a neural network and discover how a fashion specific model sees the world differently from generic visual models. Lastly, I'll demonstrate some applications of the representation learned by the model.

The initial part of this presentation will be technical but the remainder will be accessible.
