Abstract: A method of performing automatic tuning on a deep learning model includes: utilizing an instruction-based learned cost model to estimate a first type of operational performance metrics based on a tuned configuration of layer fusion and tensor tiling; utilizing statistical data gathered during a compilation process of the deep learning model to determine a second type of operational performance metrics based on the tuned configuration of layer fusion and tensor tiling; performing an auto-tuning process to obtain a plurality of optimal configurations based on the first type of operational performance metrics and the second type of operational performance metrics; and configure the deep learning model according to one of the plurality of optimal configurations.

Abstract: An analysis method and an electronic apparatus for breast image are provided. The method includes the following steps. One or more breast ultrasound images are obtained. The breast ultrasound images are used for forming a three-dimensional (3D) breast model. A volume of interest (VOI) in the breast ultrasound image is obtained by applying a detection model on the 3D breast model. The VOI is compared with a tissue segmentation result. The VOI is determined as a false positive according to a compared result between the VOI and the tissue segmentation result. The compared result includes that the VOI is located at a glandular tissue based on the tissue segmentation result. In response to the VOI being located in the glandular tissue of the tissue segmentation result, the VOI is compared with the lactiferous duct in the 3D breast model.

Abstract: A mobile RFID (Radio Frequency Identification) system and method are provided to monitor multiple control zones of the system simultaneously through a mobile outpost monitor. The control zones included in the system are connected with each other through a data exchange interface. Each of the control zones includes a link interface connecting with a gateway of at least one RFID tracking module. The gateway connects with at least one RFID reader and a signal transmitter to receive tag information of RFID tags within the control zone, and transmits the tag information through the signal transmitter. When the mobile outpost monitor moves from one control zone to another, the mobile outpost monitor may switch to link with the signal transmitter of the gateway in the current control zone. Through the data exchange interface, the mobile outpost monitor is able to obtain the monitoring information of another control zones.

Abstract: A positioning system and method are provided to use multiple RFID readers to position a target object with an active RFID tag equipped thereon. The system and method defines a geometric center of the locations of the RFID readers as a first coordinate. When the RFID readers continuously receive RF signals of the active RFID tag, a corresponding signal intensity of each of the RF signals is calculated and compared to obtain an approaching vector corresponding to the location of the RFID reader with the greatest signal intensity of the RF signal. A positioned location of the target object is then approached from the first coordinate to a second coordinate according to the approaching vector. The first coordinate and the positioned location of the target object will be reset as the second coordinate. The reset first coordinate is output as the latest positioned location of the target object.

Abstract: A handheld electronic device and mobile RFID (Radio Frequency Identification) reader equipped thereon allow a user to move to wherever necessary and sense RFID tag data of a target object. The mobile RFID reader includes a microprocessor, a memory unit connected to the microprocessor, a reader positioning unit, a RFID transceiver, a temporary data storage and a network interface. The reader positioning unit positions the location of the RFID reader to obtain reader location information of the RFID reader, and then the RFID transceiver receives a tag signal with tag ID (Identification) data from RFID tag. The reader location information and the tag ID data of the RFID tag are able to be stored optionally in the temporary data storage, and will be uploaded to a backend network sever whenever the RFID reader is connected to the backend network sever through its network interface.

Abstract: A system and method is provided to track positions of a portable electronic device. Different communication modules capable of retrieving position signals are enabled selectively according to the status/type of position signals of the portable electronic device. All of the different communication modules are enabled when the portable electronic device locates around a boundary between different regions that require different communication modules to obtain geography information. Therefore, by means of seamless transferring operation between different communication modules, a remote manager may be able to continuously monitor the positions of the portable electronic device.
