In this problem all links are undirected and unlabeled. Nodes have labels shown using different colors. |
| Our ask is to train a link predictor using [[https://dtai.cs.kuleuven.be/problog/|Problog]]. In case somebody forgot Problog installation is fairly easy given a working Python environment (''pip install problog'' and optionally ''problog install'' on Linux). In case it wasn't simple enough, one can try to use the [[https://dtai.cs.kuleuven.be/problog/editor.html|on-line interface]]. The evidence file for the problem can downloaded from {{ :en:dydaktyka:problog:link_prediction_data.pl | this link}}. | Our ask is to train a link predictor using [[https://dtai.cs.kuleuven.be/problog/|Problog]].

| + | - Try to learn structure of the Information Retrieval model, you've done earlier by hand. | ||
| + | - Is the learned model satisfying? If not, what is the problem? Try to fix it by changing learning data by hand. | ||
| + | - Modify model to consider more than only one query. What has to be changed? | ||
