Highlighted Projects

PATHS
PATHS – Pathology Transformer with Hierarchical Selection

Efficient whole slide image analysis using a hierarchical transformer and iterative patch zooming.

PairVDN
PairVDN – Pair-wise Decomposed Value Functions

A novel joint value function decomposition for multi-agent reinforcement learning. Improved expressivity, but requires maximisation through dynamic programming.

guidediffuseq
Controlling the Quality-Diversity Trade-off in Diffusion Language Models

An implementation of a token-level diffusion language model, with several novel techniques for controlling the quality-diversity trade-off.

PairVDN
Box Jump – MARL Environment

Custom multi-agent reinforcement learning environment able to scale to many agents. Designed for use with PettingZoo, and features in their third party environment list.

stable-diffusion-infinite-scroll
Stable Diffusion Infinite Scroll

A Tkinter app which uses repeated outpainting to give an infinite seamless scrolling view. Can also be used to just create really long images.

sd-variant-anim
Stable Diffusion Variant Animation

Generate random animations where each frame is an image variation of the previous frame. Uses CLIP guidance and a model finetuned to condition on image embeddings.

Generative Gaussian Splatting
Generative Gaussian Splatting

Improving Gaussian splatting reconstructions with synthetic data from a fine-tuned diffusion model.

stable-diffusion-infinite-scroll
Ganorama

Zero-shot panorama generation from pre-trained GANs by projecting features between cameras for multi-view consistency. Can also be used as a seamless sphere texture generator.

Ganimate
Ganimate

A Gradio app for creating weird GAN-based animations, with support for BigGAN and StyleGAN.

pixartdiffusion
RGBA Pixel Art Generation

A tiny diffusion model implemented + trained from scratch on 32x32 pixel art characters, with native transparency support.

whatis
Whatis – PyPI Package

A tool for explaining strange Python objects given to you in interactive sessions.
