MIT researchers have developed a new approach to detect anomalies in complex systems, such as wind turbines or satellites, using large language models (LLMs). This method can identify problems without requiring any training, making it a potentially more efficient and cost-effective solution than traditional deep-learning models. The researchers, led by graduate student Sarah Alnegheimish and principal research scientist Kalyan Veeramachaneni, created a framework called SigLLM that converts time-series data into text-based inputs that an LLM can process. They found that LLMs performed as well as some other AI approaches in detecting anomalies, although they did not beat state-of-the-art deep learning models. The research, supported by companies including SES S.A., Iberdrola, ScottishPower Renewables, and Hyundai Motor Company, could lead to the development of more efficient anomaly detection systems for complex equipment.
