Conventions used

There are a number of text conventions used throughout this book.

Code in text: Indicates code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and X (formerly Twitter) handles.

Here is an example: “When the experiment is finished executing we can grab our best model, an ITransformer, from the result’s best run via result.BestRun.Model.”

A block of code, notebook cell, or other command you might enter is set as follows:

ExperimentResult<MulticlassClassificationMetrics> result =
    exp.Execute(split.TrainSet, split.TestSet);
ITransformer model = result.BestRun.Model;
var metrics = result.BestRun.ValidationMetrics;
metrics.ConfusionMatrix.GetFormattedConfusionTable()

The output of any command is written as follows:

Confusion table
          ||========================
PREDICTED ||   Win |  Loss |  Draw | Recall
TRUTH     ||========================
      Win || 6,537 |     3 |   438 | 0.9368
     Loss ||     1 | 6,544 |   432 | 0.9379
     Draw ||   171 |   220 | 4,271 | 0.9161
          ||========================
Precision ||0.9744 |0.9670 |0.8308 |

Bold: Indicates a new term, an important word, or words that you see onscreen. For instance, words in menus or dialog boxes appear in bold. Here is an example: “A Variables pane to view variables in the kernel.”
