-====== Statistical Relational AI ====== 
  
-Statistical Relational AI (StaRAI) is a branch of Artificial Intelligence lying at the intersection between statistical and logical methods, applied to relational data. 
-This class will cover the most common types of tasks considered by the StaRAI methods. ​ 
- 
-Materials used in the class come from a workshop conducted by Marco Lippi at ACAI'​2018 summer school in Ferrara. 
- 
-Questions: 
-  - What is hidden under the term "​relational data"? 
-  - Could modern "​deep"​ learning methods work be used in the same context? 
- 
-====== Link Prediction ====== 
- 
-Given a relational model of a domain (e.g. graph of connections in the social network) we have to learn how to predict connection between nodes in similar networks. ​ 
- 
-Questions: 
-  - What types of networks can we spot in real life?  
-  - What are the possible applications of the link predictor? 
-  - What does "​similar network"​ mean? How can we validate the predictor? 
-  - What learning features can be found in the network? 
- 
-  
-===== Toy Problem ===== 
- 
-{{ :​en:​dydaktyka:​problog:​toy_link_1.png?​200|}}Let assume we have a very tiny network as shown on the right. 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}}. 
- 
- 
-Questions: 
-  - How would you write a Problog model for this task? 
-  - Do you find this kind of predictor satisfying? Would you call it "​relational"?​
