Transforming a model
The 'Transform' command ('Build' menu) enables an InterModeller model of one type to be transformed into any other type. It generates a dialog like the one below. With the settings shown, the knowledge base in the front window will be transformed into a Decision tree model that will be created in a new window, using the 'Standard' type of transformation.
The original model will not be affected. Also, if the original model contained designed dialogs and graphical images, these will be automatically copied to the transformed model.
The three main options are as follows.
Standard transform
This option is intended to give the best results in most circumstances. It aims to derive a single coherent structure of the required type, for example a single table or a single tree (but in the case of trees it may be necessary to generate more than one tree). Normally, all information is preserved. An exception is when the source model contains two or more separate structures, for example, two tables or two trees: in that case a single derived structure will contain no record of how information was originally distributed across the original structures, so the transformation may not be fully reversible.
Reversible
This option aims to derive a model that can be re-transformed exactly into the original model. This option should always preserve all the source model's information. However, the derived model is more likely to be fragmented into multiple structures than is the case with a 'standard' transformation.
Slim to essentials
This option aims to derive the minimum-sized model that is nevertheless correct in the sense that it can classify all categories in the same way as the source model. This is a 'lossy' form of transformation and typically, some information will be deleted. Click here to learn more about slimming
