This backbone allows taxonomic search, browse and reporting operations across all those resources in a consistent way and to provide means to crosswalk names from one source to another. It is updated regulary through an automated process in which the Catalogue of Life acts as a starting point also providing the complete higher classification above families.

Algorithm 1 illustrates the generic strategy for inducing decision trees. The algorithm begins with the full training set at the root node of the decision tree and recursively partitions the data into lower level nodes by pre-defined split criterion.

Some decision tree algorithms implement a special criterion to abort the induction, called stopping criterion. A simple stopping criterion is when the complete training samples belong to the class of one leaf node. This may lead to overfitting, where the decision tree might not generalize to new unseen samples.

To avoid this issues, some algorithms include methods for removing such leaf nodes from the tree, known as pruning. The ID3 algorithm is a very simple decision tree algorithm and commonly used for teaching purposes. It uses information gain as a splitting criterion and does not apply any pruning methods.

Abbildung in dieser Leseprobe nicht enthalten Figure 1: Emerging Technology Hype Cycle, source: Gartner a Because the amount of generated and stored data is rising worldwide, the number of data scientists has to grow likewise.

The challenges of creating such a decision network can be grouped into the following two categories: - Challenges relating to the development and training of the decision network, and - Challenges related to cross industry knowledge transfer. For example: - Pedestrian detection at very high frame rates. Abbildung in dieser Leseprobe nicht enthalten Table 2: Research methodologies retained for this thesis, based on: Palvia et al.
