  • Publication number: 20240069878
    Abstract: Aspects of the present disclosure provide a method for training a predictor that predicts performance of a plurality of machine learning (ML) models on platforms. For example, the method can include converting each of the ML models into a plurality of instructions or the instructions and a plurality of intermediate representations (IRs). The method can also include simulating execution of the instructions corresponding to each of the ML models on a platform and generating instruction performance reports. Each of the instruction performance reports can be associated with performance of the instructions corresponding to one of the ML models that are executed on the platform. The method can also include training the predictor with the instructions or the IRs as learning features and the instruction performance reports as learning labels, compiling the predictor into a library file, and storing the library file in a storage device.

  • Publication number: 20230196526
    Abstract: A system stores parameters of a feature extraction network and a refinement network. The system receives an input including a degraded image concatenated with a degradation estimation of the degraded image; performs operations of the feature extraction network to apply pre-trained weights to the input to generate feature maps; and performs operations of the refinement network including a sequence of dynamic blocks. One or more of the dynamic blocks dynamically generates per-grid kernels to be applied to corresponding grids of an intermediate image output from a prior dynamic block in the sequence. Each per-grid kernel is generated based on the intermediate image and the feature maps.

  • Publication number: 20230064692
    Abstract: According to a network space search method, an expanded search space is partitioned into multiple network spaces. Each network space includes a plurality of network architectures and is characterized by a first range of network depths and a second range of network widths. The performance of the network spaces is evaluated by sampling respective network architectures with respect to a multi-objective loss function. The evaluated performance is indicated as a probability associated with each network space. The method then identifies a subset of the network spaces that has the highest probabilities, and selects a target network space from the subset based on model complexity.

  • Publication number: 20230006611
    Abstract: A compensator compensates for the distortions of a power amplifier circuit. A power amplifier neural network (PAN) is trained to model the power amplifier circuit using pre-determined input and output signal pairs that characterize the power amplifier circuit. Then a compensator is trained to pre-distort a signal received by the PAN. The compensator uses a neural network trained to optimize a loss between a compensator input and a PAN output, and the loss is calculated according to a multi-objective loss function that includes one or more time-domain loss function and one or more frequency-domain loss functions. The trained compensator performs signal compensation to thereby output a pre-distorted signal to the power amplifier circuit.

  • Patent number: 10614645
    Abstract: An intelligent door lock, a control method thereof, and an unlocking apparatus and method thereof are provided. The unlocking method is adapted for an unlocking apparatus to unlock a door lock apparatus, and includes following steps. Receiving a plurality of broadcast packages sent by the door lock apparatus in response to an operation on the door lock apparatus, and detecting a variation in signal strengths of the broadcast packets caused by the operation. Reading a stage message, which is recorded in each of the broadcast packages, of the door lock apparatus corresponding to the operation. Determining whether a variation of the stage messages matches a variation of the signal strengths of the broadcast packages. Sending an unlocking signal to the door lock apparatus for executing unlocking if a determination result indicates match.

  • Patent number: 8427476
    Abstract: A display system for improving visual comfort and a method of adaptively adjusting resolution of a display device are provided. The display system includes a display device, a memory, an image sensor, a face recognition unit, a distance detection unit, and a controller. The memory stores face representation data and user preference data. The image sensor captures an image and converts it into an electrical signal. The face recognition unit analyzes that electrical signal to recognize a face image and compares the recognized face image with the face representation data to generate a first signal. The distance detection unit analyzes the electrical signal to determine a distance between the display device and the user to generate a second signal. The controller then generates a parameter based on the first signal and the second signal and adjusts a display resolution of the display device based on the parameter.
