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.
The `annTrain` action, part of the `neuralNet` action set, is used to train an artificial neural network (ANN) in SAS Viya. This process involves adjusting the network's weights based on a given dataset to minimize prediction errors. The action supports various architectures like Multi-Layer Perceptrons (MLP), Generalized Linear Models (GLIM), and direct connection models. It offers extensive customization options, including different activation functions, optimization algorithms (like LBFGS and SGD), and data standardization methods, making it a versatile tool for building predictive models.
