Industry PhD Scholarship: Generative Models in the Fourier Domain

Generative Models in the Fourier Domain

Description

The Data Science Institute (DSI) at the University of Technology Sydney (UTS) is a world leader in data science and ethical artificial intelligence and has a strong focus on Industry engagement. The DSI boasts over 200 PhD students and 100 academic staff with award winning researchers in AI 

In collaboration with Leonardo.Ai we are advertising an industry PhD program that will tackle research questions at the bleeding edge of GenAI research with an aim to drive forward both foundational research in the field through traditional publication outputs, as well as supercharging the Leonardo.Ai platform. Leonardo.Ai is a world leader in generative AI and is building one of the leading AI laboratories in foundational AI research. Leonardo.Ai has also recently been acquired by Canva and now hosts over 200 million users through the combined platforms. Both Leonardo.Ai and Canva have strong principles in: being a good human being foremost, maximizing impact, moving at speed and owning our goals and winning together.   

Project Aims

The overarching aim of this PhD is to explore and leverage the frequency domain (and other under-explored representations of pixel space) in training generative AI models across modalities e.g. image, video etc. The aim is to mode-reverse the diffusion process by using an autoregressive transformer (or similar techniques) to iteratively predict the frequency coefficients (and phase values) of the frequencies of an image, from low to high. In model training and inference we do observe low frequency components being initiated in the early generation steps, indicating that the denoising / attention process favors a starting point of broad scale structure.  Effectively the Fourier domain is an underexplored space in training generative models and we want to exploit these techniques to produce state-of-the-art capabilities.  

PhD research students will have access to leading edge compute facilities (e.g. H100s), a team of world class research leaders across both UTS, Leonardo and Canva, cutting edge datasets to conduct research, and mentoring and guidance to complete a best-in-class PhD research program. 

Eligibility

We are looking for the best of the best! You will be adequately qualified to enter the UTS PhD scheme with Undergraduate / Postgraduate Qualifications in e.g. Computer Science, Data Science, AI, Physics, Mathematics or equivalent.   

Candidate Profile

• A strong background in programming, mathematics, statistics, physics or signal processing. 

• Knowledge and interest in Diffusion, GANs, LLMs and generative AI in general as demonstrated by independent project work in GitHub. 

• Proficiency in modern deep learning frameworks such as Pytorch or Jax.  

• Ideally, we are looking for candidates with previous experience in top-tier Tech companies. We, however, welcome applications from underrepresented groups and diverse backgrounds.

• Proficiency in English (both Verbal and Written). 

Location 

This PhD will be hosted at the University of Technology Sydney and the student will spend significant time at the Leonardo.Ai headquarters, which is located on the waterfront in North Sydney (20 mins train ride from UTS).  

Full Domestic Scholarship: Open to Australian citizens who will receive a full scholarship of $37k per year stipend + $10k per year top-up for 3.5 years. 

Full International Scholarship: Open to all international applicants with $37k per year stipend, $45k per year international fees and $30k per year top-up for 3.5 years. Student visas will be provided by UTS.
