seldonian.parse_tree.zhat_funcs.vector_Accuracy

vector_Accuracy(model, theta, X, Y, **kwargs)

Calculate probabilistic accuracy for each observation. This is the probability of predicting the correct label, and equivalent to 1 - error rate.

Parameters:

• model – SeldonianModel instance

• theta (numpy ndarray) – The model weights

• X (numpy ndarray) – The features

• Y (numpy ndarray) – The labels

Returns:

Error rate for each observation

Return type:

numpy ndarray(float between 0 and 1)
