Estimates the category probabilities of new observations using a fitted SPNN.
1 | spnn.predict(nn, newData)
|
nn |
A trained Scaled Invariant Probabilistic Neural Network. |
newData |
A matrix of new observations where each row represents a single observation vector. |
Given a trained Scale Invariant Probabilistic Neural Network and new data, the function spnn.predict returns the category with the highest probability and the probability estimates for each category.
A list of the guessed categories and the probability estimates of each category.
