CLIP-GPT

Initial exploration of fine-tuning GPT-2 for interleaved CLIP embedding input and output. The goal of this project is to showcase that GPT is able to directly reason across multiple modalities.

Data

This exploration makes use of MS-COCO's 2017 training image and caption pairs, which can be downloaded here.

Fine-tuning

We provide a notebook which details our experimental setup and fine-tuning procedure and the following video description:

IMAGE ALT TEXT HERE

Will be continuing to elaborate and iterate on the method as we continue.

Results

Caption to CLIP

Using cosine similarity we compute the top-k nearest neighbors for a predicted embedding within the MSCOCO training image set.

Caption COCO Nearest Neighbor
A woman riding a bike amongst other vehicles. Woman Biking
A child reading a book. Child with Book

CLIP to Caption

Captions produced after passing a CLIP embedding as input.

Encoded Image Caption
Cake on a Plate A piece of cake and a fork on a table.
Two Giraffes Two giraffes are standing next to a fence.

TODO
