- | To limit the combinatorial explosion in pathway prediction, enviPath allows to learn and apply relative reasoning models. Rule-based relative reasoning models are available, as well as multi-label machine learning algorithms. If employed during pathway prediction, models predict probabilities for each applied rule and the corresponding educt and product compound, and can thus be used to truncate the predicted pathway. | + | |

- | Moreover, the user can train own such models on any collection of packages. Hence, new models can reflect exactly the conditions of the selected packages, and predicted probabilities are automatically adapted to the type of data used as input in the training process. In more detail, relative reasoning models will be trained on all compounds, rules and reactions that are available within the selected package/s. | + | Moreover, the user can train own such models on any collection of packages.

Individual machine learning models can be trained based on the structure of a set of compounds and all transformation rules triggered by them. These models can predict probabilities for all transformations of a new compound. As the learning problem clearly is a so called multi-label classification problem, we extended the machine learning approach using multi-label classifiers to improve the prediction. | Individual machine learning models can be trained based on the structure of a set of compounds and all transformation rules triggered by them.
