Green AI: Making Machine Learning Environmentally Sustainable • Charles Humble • YOW! 2025

Charles Humble explores the significant environmental impact of AI, particularly generative AI, on global carbon emissions. He offers practical, actionable strategies across the entire AI lifecycle—from project planning and data collection to training and deployment—to reduce this footprint. Key recommendations include questioning the necessity of AI solutions, choosing open-source models, leveraging carbon-aware computing for demand shifting, employing model compression techniques like distillation and quantization, and integrating sustainability as a fundamental architectural principle in software engineering.

Intern talk: Distilling Self-Supervised-Learning-Based Speech Quality Assessment into Compact Models

This research explores the distillation and pruning of large, self-supervised speech quality assessment models into compact and efficient versions. Starting with the high-performing but large XLSR-SQA model, the work details a process of knowledge distillation using a teacher-student framework with a diverse, on-the-fly generated dataset. The resulting compact models successfully close over half the performance gap to the teacher, making them suitable for on-device and production applications where model size is a critical constraint.
