Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In retail environments, especially in optician shops, there is a challenge in sharing sensitive customer data for personalized services while adhering to data protection regulations and maintaining customer confidentiality.
Innovation Solution
A computing device equipped with a local neural network that processes and analyzes data related to wearers or prospective wearers of head-wearable devices, enabling predictive and personalized services, and an interface module that facilitates participation in a federated learning process with a global neural network.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If customer data is centralized and shared to improve predictive models, then model accuracy is improved, but data privacy and confidentiality are compromised
Solution Approach 1:
The system segments the centralized data processing into distributed local neural networks at each retail location. Each local network processes data independently without centralizing sensitive customer information, thereby maintaining data privacy while still enabling collaborative learning through federated averaging of model parameters.
Solution Approach 2:
A server acts as an intermediary that coordinates the federated learning process by collecting model parameters from local neural networks and distributing updated global models. This intermediary enables collaborative model improvement without directly sharing sensitive customer data between locations.
2Object-affected harmful factors
If data is not shared across retail locations, then data privacy is maintained, but predictive model effectiveness is limited due to lack of collective experience
Solution Approach 1:
The federated learning system implements a feedback loop where local neural networks send model parameters to a central server, which aggregates them into an updated global model. This updated model is then distributed back to local networks, enabling continuous improvement of predictive accuracy while maintaining data privacy through iterative collaborative learning.
3Measurement precision
If large volumes of customer data are collected to improve machine learning models, then model performance is enhanced, but compliance with data protection regulations becomes difficult
Solution Approach 1:
The system extracts only the essential model parameters and gradients needed for training from local data, leaving the sensitive customer data at each retail location. This extraction approach enables model improvement while removing the need to centralize or share protected customer information, ensuring regulatory compliance.
