A New Breakthrough in On-Device Training
Personalized deep-learning models have the potential to revolutionize artificial intelligence applications, enabling chatbots and smart keyboards to adapt to user preferences. However, the traditional approach of updating these models by uploading user data to cloud servers poses challenges in terms of energy consumption and data security. Researchers from MIT, the MIT-IBM Watson AI Lab, and the University of California San Diego have developed an innovative technique called PockEngine that allows deep-learning models to be efficiently updated directly on an edge device.
Efficiency and Accuracy Boost
PockEngine is an on-device training method that identifies specific parts of a machine-learning model that require fine-tuning for better accuracy. By computing and storing only these specific pieces, PockEngine minimizes computational overhead and significantly speeds up the training process compared to other methods. In fact, it can perform up to 15 times faster on certain hardware platforms. Moreover, PockEngine does not compromise the accuracy of the models and has been shown to enhance the ability of AI chatbots to answer complex questions.
Privacy and Cost Benefits
On-device fine-tuning using PockEngine offers several advantages, including enhanced privacy and lower costs. By eliminating the need to transmit sensitive user data to cloud servers, privacy concerns are mitigated. Additionally, the reduction in computational overhead and energy consumption contributes to cost savings. PockEngine opens up new possibilities for customization and lifelong learning while working with limited resources on edge devices.
How PockEngine Works
PockEngine optimizes the fine-tuning process by selectively updating and storing important layers of the deep-learning model. Not all layers contribute equally to improving accuracy, and PockEngine identifies the optimal trade-off between accuracy and fine-tuning cost. This technique is performed during compile time, prior to runtime, which reduces the computational burden during execution. It creates a streamlined graph of the model, removing unnecessary layers or pieces of layers to enhance efficiency.
Real-World Applications
The benefits of PockEngine extend to various edge devices, including smartphones, Raspberry Pi computers, and Apple M1 Chips. On these devices, PockEngine achieves on-device training speeds up to 15 times faster without sacrificing accuracy. The technique has also been successfully applied to large language models, where fine-tuning is crucial for tasks such as answering complex questions. PockEngine has proven to be a game-changer, as it significantly reduces the time required for the fine-tuning process without compromising the model’s performance.
