UCLA’s Neha Prakriya shares data-efficient training methods that cut compute costs and improve performance on AMD MI300X GPUs.

Data-Efficient Training on AMD GPUs

At the Beyond CUDA Summit, Neha Prakriya, PhD student at UCLA and AMD intern, gave a compelling presentation on how her lab is tackling one of AI’s biggest bottlenecks: the memory wall.

As models grow, training costs are skyrocketing—up to 750x increases every two years—while memory and bandwidth improvements lag behind. Neha’s team is flipping the script with software-driven data efficiency methods, making training on AMD GPUs like the MI300X smarter, faster, and leaner.

🚧 The AI Memory Wall: A Hardware-Software Mismatch

Despite rapid model scaling, hardware improvements in memory bandwidth and interconnects haven’t kept up. This gap—dubbed the memory wall—is limiting GPU performance. While some are solving it with better hardware, UCLA’s team is attacking the problem from the data side.

Their approach: optimize what goes into the model, not just how it’s trained.


🔁 Smart Data Selection: Learn, Focus, Review

Inspired by human learning techniques like spaced repetition, Neha’s team developed an iterative method for selecting the most impactful data during training. Instead of blindly feeding massive datasets into the GPU, they:

 1. Learn: Sample broadly from the dataset.
 2. Focus: Identify hard examples based on loss trajectories and prioritize them.
 3. Review: Reintroduce easier examples to avoid forgetting.

💡 Result: Better models trained on fewer tokens, saving time and compute.


📉 Results: 130B Tokens > 1T Tokens

Using this method, they trained Open LLaMA-style models with just 130B carefully selected tokens, outperforming baselines trained on 1 trillion tokens.

They also:

 * Trained models from 300M to 7B parameters.
 * Outperformed random sampling and static selection baselines.
 * Open-sourced models and code on GitHub (link placeholder).


🧪 Domain Adaptation: Fine-Tuning, Smarter and Faster

When adapting pre-trained models to specialized domains like math, code, or medicine, Neha’s team used proxy models to identify and cluster impactful training samples. This:

 * Cut fine-tuning time by 2x
 * Maintained or improved accuracy across both in-domain and out-of-domain tasks

Crucially, the clustering info from small models transferred reliably to larger ones—enabling scalable, smart fine-tuning.


💻 Real-World Impact: FPGA Coding Assistant on AMD MI300X

Thanks to AMD’s HPC grant program, the team gained access to AMD Instinct™ MI300X GPUs for applied research. Their current project:

 * Training an HLS coding assistant to help developers optimize code for FPGAs
 * Tackling a solution space with 3M+ possible design points
 * Leveraging a dataset of 40,000+ circuit designs, built over a decade

This tool aims to reduce the friction of FPGA adoption by automating pragma selection and resource prediction.


🤝 Open to Collaboration

Neha wrapped her talk with a call for collaboration—especially from industry partners interested in scaling these innovations. As her team looks to bring data-efficient training to a broader set of use cases and hardware targets, the door is open.
