Parameter-Efficient Fine-Tuning with Bottleneck Adapters in PyTorch: Scalable NLP Model Optimization

Transformer-based models have revolutionized AI but demand significant computational and storage resources during fine-tuning. This session introduces bottleneck adapters, a Parameter-Efficient Fine-Tuning (PEFT) technique that optimizes training and deployment of large neural networks using PyTorch.

Attendees will learn to implement adapters—lightweight modules that update only a small fraction of a model’s parameters while preserving pre-trained weights. Topics include:

Efficient Training: Achieve faster convergence by fine-tuning fewer parameters.

Compact Storage: Save task-specific adapter weights, reducing memory overhead.

Reduced Overfitting: Retain most of the original model structure to improve generalization.

The presentation walks through fine-tuning a transformer for NLP tasks, comparing PEFT with full fine-tuning and LoRA techniques. Attendees will leave with actionable skills for building scalable, resource-efficient AI workflows, leveraging PyTorch's flexibility to solve real-world challenges.
