Model Compression Techniques
Model compression techniques, including quantization, pruning, and knowledge distillation, are critical for reducing the size and computational demands of LLMs. Quantization reduces bit precision (e.g., FP32 to INT8) by up to 75%, significantly lowering memory footprint and computational cost. Pruning removes less significant parameters, while knowledge distillation transfers insights from larger 'teacher' models to smaller 'student' models, maintaining accuracy on edge devices.
Architectural & Algorithmic Optimizations
Optimizing the core Transformer architecture and inference algorithms is vital for edge deployment. Techniques like efficient Transformer variants (e.g., Linformer, Performer, GQA) reduce the quadratic complexity of self-attention to linear scaling, improving speed and memory. Inference optimizations such as speculative decoding and KV cache management further enhance real-time responsiveness by predicting tokens and efficiently storing key-value pairs.
System-Level and Hybrid Approaches
This category involves strategies beyond single-model optimization, including edge-cloud collaboration (model partitioning, task offloading), on-device fine-tuning (PEFT methods like LoRA), and federated learning. These approaches leverage distributed resources, enable personalized models without raw data sharing, and maintain privacy, ensuring robust and scalable LLM deployment in heterogeneous edge environments.
Hardware & Software Considerations
Effective LLM deployment on edge devices requires careful selection of hardware platforms and inference frameworks. Specialized accelerators like NPUs, TPUs, and FPGAs offer significant energy efficiency and performance gains over traditional CPUs/GPUs for AI workloads. Software frameworks like TensorFlow Lite, ONNX Runtime, and llama.cpp provide optimized tools for model conversion, quantization, and efficient execution on resource-constrained devices, bridging the gap between training and deployment.
75%
Average Model Size Reduction with Quantization
Quantization methods, such as converting models from FP32 to INT8, can reduce the memory footprint of Large Language Models by up to 75% without significant accuracy degradation. This is crucial for deploying LLMs on resource-constrained edge devices where memory and computational power are limited, as highlighted in the paper's section 3.1.1.

Enhanced Data Privacy & Scalability with Federated Learning
Problem: Centralized Data Challenges
Deploying LLMs often involves centralizing vast amounts of sensitive user data, raising significant privacy concerns and compliance risks (GDPR, HIPAA). This limits the adoption of powerful AI in privacy-sensitive sectors like healthcare.
Solution: Decentralized Training
Federated Learning (FL) allows LLMs to be trained across multiple edge devices without ever sharing raw data. Only aggregated model updates (gradients) are sent to a central server. This approach ensures sensitive data remains local, significantly enhancing user privacy and security.
Enterprise Impact: Privacy, Performance, and Personalization
FL enables organizations to leverage diverse datasets for robust model training while complying with stringent data protection regulations. It also reduces communication costs by transmitting only small model updates and fosters personalized AI experiences on-device, critical for dynamic, real-time applications where user data integrity is paramount.
