ai_hamspamclassifierprojectaueb

Email Ham-Spam Classifier for the dataset "enron3" (http://nlp.cs.aueb.gr/software_and_datasets/Enron-Spam/preprocessed/enron3.tar.gz) using 3 methods: -Naive Bayes Classifier -ID3 Classifier with pre-Pruning -AdaBoost Classifier using Decision Stump as week learner Implemented in Java and written as a project in terms of the subject Artificial Intelligence in AUEB.

ai_pl_fol_inference_prologcloneprojectaueb

Resolution Inference Methods for mathematical logic using resolution for Propositional Logic CNF and Horn clauses, as well as the forward chaining method for First Order Logic Horn Clauses, implemented in Java. The First Order Logic forward chaining method implementation tries to imitate an alternative approach to the Prolog Language (which uses backward chaining method). This was written as a project in terms of the subject Artificial Intelligence in AUEB.

ai_schoolscheduleprojectaueb

A class scheduling program for a high school, which takes as input the teachers, lessons and some restrictions and finds one of the best valid solutions ( schedules that meet all restrictions and are fair for all the teachers ). Implemented in Java, the program uses 3 different algorithms: A*, Beam Search and a modified version of A* which combines A* with Hill Climbing and Beam Search, generating the best results. This program was written as a project in terms of the subject Artificial Intelligence in AUEB.
