SamplingNeuralNetwork.probability_gradients

SamplingNeuralNetwork.probability_gradients(input_data, weights)

Probability gradients of histogram resulting from the network. Format depends on the set interpret function. Shape is (input_grad, weights_grad), where each grad has one dict for each parameter and each dict contains as value the derivative of the probability of measuring the key.

Parameters

• input_data (Union[List[float], ndarray, float, None]) -- input data of the shape (num_inputs). In case of a single scalar input it is directly cast to and interpreted like a one-element array.

• weights (Union[List[float], ndarray, float, None]) -- trainable weights of the shape (num_weights). In case of a single scalar weight it is directly cast to and interpreted like a one-element array.

Return type

Tuple[Union[ndarray, SparseArray], Union[ndarray, SparseArray]]

Returns

The probability gradients.
