Description:
CROSS REFERENCE TO RELATED APPLICATIONS 
     The present application claims priority to Swedish Patent Application No. 2151346-0, filed Nov. 2, 2021, the content of which is incorporated herein by reference in its entirety. 
     TECHNICAL FIELD 
     The present disclosure pertains to the field of Internet of things (IoT) and detection devices, and relates to an electronic device and to a method for adapting a detection model. 
     BACKGROUND 
     Today, in building management, there is an increase in the use of internet of things devices (IoT devices) for enabling smart buildings. A building or group of buildings can include hundreds of IoT devices (such as smart television, TVs, smart speakers, dedicated connected sensors such as temperature sensors, cameras, microphones, etc.) with a wide range of specifications. Many of the desired features for smart buildings require combining these devices and their sensors with machine learning (ML), and in many cases, the machine learning inference needs to run on the IoT device. Managing a large number of IoT devices and their software in general, and ML models in particular, may be a complex task with many challenges. 
     SUMMARY 
     Flexible IoT device application environments for remote and/or over-the-air application update of devices may be used. For example, software, such as applications, may be deployed to IoT devices and not necessarily the whole firmware. 
     Environments as disclosed herein may act as a software layer separating applications and platform firmware, making applications hardware agnostic. Dynamic deployment may therefore be enabled for both applications and ML models, such as from a cloud. 
     A remaining challenge of deploying ML models is, for example, how to provide a ML model that performs optimally given the device capability, nearby devices, and/or the environment the device is located in (such as sitting in). It may be envisaged to provide a generic model, that is known to fit the IoT device capabilities. However, by using a generic model not tailored to the environment, the ML model may underperform. 
     Another challenge of providing a generic model, may be that it may not leverage the capabilities of nearby devices. 
     Accordingly, there is a need for electronic devices and methods for adapting a detection model (such as a ML model) which may mitigate, alleviate, or address the shortcomings existing and may provide deployment of a detection model which may be adapted (such as tailored) to an electronic device (such as IoT device). A detection model may be adapted to an environment of an electronic device (such as IoT device). 
     An electronic device is provided. The electronic device comprises memory circuitry, processor circuitry, and interface circuitry. The electronic device is configured to obtain first data comprising a plurality of electronic device identifiers and a plurality of capability parameters comprising for each electronic device a capability parameter indicative of a capability of a corresponding electronic device of the plurality of electronic devices. The electronic device is configured to determine, based on the plurality of capability parameters, a first cluster of one or more electronic devices. The electronic device is configured to determine, based on the capability parameter of each of the one or more electronic devices of the first cluster, a first configuration parameter for obtaining a first detection model to be applied by one or more electronic devices of the first cluster. The electronic device is configured to transmit the first detection model to the one or more electronic devices of the first cluster. The electronic device is configured to determine, based on a proximity parameter, a second cluster of electronic devices. Optionally, the electronic device is configured to obtain, from the second cluster, detection data obtained by one or more electronic devices of the second cluster by applying the first detection model. The electronic device is configured to determine, optionally based on the detection data, a performance parameter of the first detection model when running on an electronic device of the second cluster. The electronic device is configured to determine, based on the performance parameter, a second configuration parameter for the first detection model to provide an updated first detection model. The electronic device is configured to transmit the updated first detection model to one or more electronic devices of the second cluster. 
     Further a method performed by an electronic device is disclosed. The method comprises obtaining first data comprising a plurality of electronic device identifiers and a plurality of capability parameters comprising for each electronic device a capability parameter indicative of a capability of a corresponding electronic device of the plurality of electronic devices. The method comprises determining, based on the plurality of capability parameters, a first cluster of one or more electronic devices. The method comprises determining, based on the capability parameter of each of the one or more electronic devices of the first cluster, a first configuration parameter for obtaining a first detection model to be applied by one or more electronic devices of the first cluster. The method comprises transmitting the first detection model to the one or more electronic devices of the first cluster. The method comprises determining, based on a proximity parameter, a second cluster of electronic devices. The method comprises obtaining, from the second cluster, detection data obtained by one or more electronic devices of the second cluster by applying the first detection model. The method comprises determining, based on the detection data, a performance parameter of the first detection model when running on an electronic device of the second cluster. The method comprises determining, based on the performance parameter, a second configuration parameter for the first detection model to provide an updated first detection model. The method comprises transmitting the updated first detection model to one or more electronic devices of the second cluster. 
     Further, a system is disclosed herein, the system comprising an electronic device as disclosed herein and one or more electronic devices (such as IoT devices) of a cluster as disclosed herein. 
     The disclosed electronic device, related method, and system may provide an improved adaption of a detection model (such as a ML model) and an improved transmittal (such as deployment and/or distribution) of a detection model which may be adapted (such as tailored) to an electronic device (such as IoT device). The present disclosure may provide an adaption of a detection model based on a capability and/or a performance of one or more electronic devices (such as a cluster of electronic devices). Further, the present disclosure may provide a detection model which may be adapted to an environment of an electronic device (such as IoT device). In other words, the present disclosure may provide an improved capacity usage of a detection model when applied by one or more electronic devices. 
     It may be appreciated that the present disclosure may provide the possibility to maintain a performance (such as a detection performance) of an electronic device when running a detection model. For example, the present disclosure may provide the possibility to maintain a performance (such as a detection performance) of an electronic device when running a detection model. For example for a prioritized detection task (such as detection classes), even with significant reduction of a detection model size (such as ML model size). 
     Further, the present disclosure may enable cooperation with other electronic devices (such as IoT devices) with other electronic devices (such as IoT devices), for example for collaborating on solving a ML task. For example, an electronic device may only have the capability of detecting a single keyword, item, object, and/or face, but several electronic devices may be capable of collaborating for detecting more keywords, items, objects, and/or faces. For example, a single electronic device may have a small vocabulary of detectable keywords, but several devices in one location may cooperate to detect a larger set of keywords, for example a complete sentence, such as by adapting a detection model, for example by distributing the keywords amongst the electronic devices. 
     Further, an advantage of the present disclosure may be that when a detection model is under-performing (such as having over-capacity) when applied by one or more electronic devices, an overlap of detection between one or more electronic devices and/or a prioritizing of a detection type may be applied. For example, the present disclosure may allow overlapping of detection of certain detection classes and/or enabling voting (such as prioritizing) between one or more electronic devices. For example, a most confident detection may be prioritized (such as selected) among the detections performed by one or more electronic devices.
