In this example the trainer will process the training data for 10 epochs. The last section in this configuration file describes options for how the the trainer will operate. A four layer fully connected decoder of 32 cells in each layer is specified for this output feature. Because thes values are not conventional binary values, i.e., "True" and "False", a feature specific preprocessing option is specified to indicate which string (" >50K") is interpreted as "True". This is a binary feature with two possible values: " 50K". In this example, there is one response variable called income. The combined data is passed through a three layer fully connected network of 128 cells in each layer with dropout regularization. This example uses the concat combiner, which simply concatenates the output of the input feature encoders. The 'combiner' section defines how the input features are combined to be passed to the output decoder. The input_features section describes each of the predictor variables, i.e., the column name and type of input variable: number or category Numeric missing values are filled in with the mean of non-missing values. All numeric features are z-scored normalized, i.e., mean centered and scaled by the standard deviation. By tabular data we mean any dataset that is composed by rows and columns similar to the data used in a spreadsheet such as the example shown in. Perhaps Saturday and Sunday have similar behavior, and maybe Friday behaves like an average of a weekend and a weekday. This approach allows for relationships between categories to be captured. Please refer to the Configuration Section for all the details.įirst, the defaults section defines the global preprocessing options. A key technique to making the most of deep learning for tabular data is to use embeddings for your categorical variables. Only the options used in this example are described. This example only covers a small fraction of the options. There is a vast array of options to control the learning process. The Ludwig configuration file describes the machine learning task.
