The `annScore` action scores a data table using a pre-trained artificial neural network model. This is a crucial step after training a model with `annTrain`, allowing you to apply the learned patterns to new data to make predictions. The action can generate various outputs, including predicted values, probabilities for classification tasks, and even the values of hidden layer nodes, which can be useful for feature engineering or model interpretation.
The annCode action generates SAS DATA step scoring code from a trained artificial neural network model. This allows for the deployment of the model outside of the CAS environment, enabling scoring of new data in traditional SAS environments. The generated code can be saved to a CAS table for further use.
La acción `annTrain` entrena una red neuronal artificial. Permite definir la arquitectura de la red (como MLP, GLIM), especificar las funciones de activación y de combinación, y configurar el proceso de optimización utilizando diversos algoritmos como LBFGS o SGD. Esta acción es fundamental para construir y ajustar modelos de redes neuronales sobre datos en CAS.
