STELLA framework enables LLMs for on-device human activity recognition

By PulseAugur Editorial · [1 sources] ·

Researchers have developed STELLA, a novel framework designed to enable large language models (LLMs) for on-device human activity recognition (HAR). This system efficiently translates raw sensor data into compact latent tokens, which are then processed by a frozen LLM. STELLA also incorporates on-device personalization by adapting a lightweight tokenizer, allowing for continuous improvement as user-specific data accumulates. The framework achieves state-of-the-art performance across multiple datasets and settings, demonstrating real-time inference capabilities within practical mobile and edge computing constraints. AI

IMPACT Enables efficient, private, and personalized LLM-based human activity recognition on edge devices.

    STELLA: Efficient Sensor-to-LLM Translation for On-Device Human Activity Recognition

    arXiv:2607.03089v1 Announce Type: cross Abstract: HAR is increasingly expected to run continuously on edge devices, yet recent LLM-based methods remain hard to deploy: raw sensor prompts are long, cloud inference adds latency and privacy risk, and fine-tuned LLM pipelines turn ge…
