  • Publication number: 20230409868
    Abstract: Activation scaled clipping layers for neural networks are described. An activation scaled clipping layer processes an output of a neuron in a neural network using a scaling parameter and a clipping parameter. The scaling parameter defines how numerical values are amplified relative to zero. The clipping parameter specifies a numerical threshold that causes the neuron output to be expressed as a value defined by the numerical threshold if the neuron output satisfies the numerical threshold. In some implementations, the scaling parameter is linear and treats numbers within a numerical range as being equivalent, such that any number in the range is scaled by a defined magnitude, regardless of value. Alternatively, the scaling parameter is nonlinear, which causes the activation scaled clipping layer to amplify numbers within a range by different magnitudes. Each scaling and clipping parameter is learnable during training of a machine learning model implementing the neural network.

  • Publication number: 20220260394
    Abstract: Systems and methods of signal processing for sensors are disclosed. Signal processing methods and systems demodulate the optical interference phase of cascaded individual optical fiber intrinsic Fabry-Perot interferometric sensors in a coherent microwave-photonic interferometry distributed sensing system. The chirp effect of an electro-optic modulator (EOM) is used to create a quasi-quadrature optical interference phase shift between two adjacent pulses which correspond to two adjacent reflection points in the time domain. The phase shift can be controlled by adjusting the bias voltage that is applied to the EOM. The interference phase is calculated by elliptically fitting the phase shift. The interference phase change is proportional to the optical path difference (OPD) change of the interferometer, and the sign can be used to differentiate the increase or decrease of the OPD. The approach shows good linearity, high resolution, and large dynamic range for distributed strain sensing.
