  • Publication number: 20250238656
    Abstract: The present invention relates a multimodal emotion recognition system with edge AI accelerator. The system employs a Fuzzy Long-Short Recurrent Convolutional Network (Fuzzy LRCN) for multiple emotion classifications. The algorithm strategically utilizes only eight channels of electroencephalogram (EEG) signals and combines electrocardiogram (ECG) and photoplethysmogram (PPG) through a fuzzification engine to improve emotion recognition accuracy with minimal hardware resource consumption. The goal is to optimize hardware resource utilization, reduce system power consumption, and maximize emotion recognition accuracy. The fuzzy algorithm provides a lightweight multimodal AI model to address the issue of increased computational load caused by recognizing emotions from multiple signals.

    Abstract: Systems, devices, media, and methods are presented for testing the capability of a mobile device to run a particular feature of an application. Each feature may include a package of code, a call, a state, and a condition; each condition correlated with a specific state. The call is a query that includes instructions to evaluate whether the application will run successfully if a particular feature is running. If the call fails, the feature condition remains Off, resulting in a rollback of the feature. If the call succeeds, the feature condition is changed to On. The system may include an experimentation framework on each mobile device for registering features, executing calls, logging results, and maintaining states and conditions.
