  • Patent number: 12210954
    Abstract: A point estimate value for an individual is computed using a Bayesian neural network model (BNN) by training a first BNN model that computes a weight mean value, a weight standard deviation value, a bias mean value, and a bias standard deviation value for each neuron of a plurality of neurons using observations. A plurality of BNN models is instantiated using the first BNN model. Instantiating each BNN model of the plurality of BNN models includes computing, for each neuron, a weight value using the weight mean value, the weight standard deviation value, and a weight random draw and a bias value using the bias mean value, the bias standard deviation value, and a bias random draw. Each instantiated BNN model is executed with the observations to compute a statistical parameter value for each observation vector of the observations. The point estimate value is computed from the statistical parameter value.

    Abstract: A light-emitting-diode driver structure applicable to driving a display panel and operation method thereof are provided. The LED driver structure includes at least one LED driving group, and the LED driving group is composed of a plurality of LED driving circuits which are serially connected in cascade. Each LED driving circuit of the LED driving group receives a data input signal in common. Upon receiving control signals, output signals are generated to drive the display panel. The multi-point driving circuit scheme can be fully or partially applied in the driver structure as required. In addition, a plurality of enable signals can be further adopted to activate each LED driving circuit, for avoiding the FIFO register used in the prior arts. By employing the disclosed technical contents, the present invention is effective in reducing both redundant power waste and circuit layout area of a conventional LED driver.
