Finally, the last classifier. Will it be the best one at the end? Yes! Previous SVM classification will be replaced by a discriminant analysis model. Discriminant analysis in short: its principle is very similar to the naive Bayes approach – Read more…
Our journey to find the best classifier is not yet at the end. The last introduced classifier was the naive Bayes and now the next one – support vector machine itself – has a difficult task to win this competition. Read more…
Same task, but third classification algorithm – naive Bayes. I was looking forward, because a MATLAB script was already written and I naively thought my only work is to replace one function name (fitcknn to fitcnb). My good mood lasted Read more…
Rád by som predstavil aspoň malú časť z projektov, na ktorých môžu pracovať študenti na Ústave informatizácie, automatizácie a matematiky. Bez ohľadu na to, či veríme alebo neveríme v nastupujúcu priemyselnú revolúciu obsiahnutú v koncepte Industry 4.0, faktom zostáva, že Read more…
The aim of this project is still the same, only a classification algorithm will be different. No more trees anymore. They will be replaced by nearest neighbors, but the method is the same as previously. K-nearest neighbors (k-NN) is a Read more…
Warning: this story has no happy ending. In the previous post I promised that we will grow better trees. For these kinds of problems optimization is used. In MATLAB, function fitctree which returns fitted classification tree can have an additional Read more…
In the introductory post, I explained why artificial intelligence and machine learning matters. Leave out sci-fi machines aside, we have to start somewhere – for example with trees. Goals have been set: we want to predict a class of wine Read more…
Čím je podľa vás zaujímavá táto štvorcová matica na Sagrada Familia? Odpoveď nájdete na týchto fotografiách:
Artificial intelligence (AI) – you probably have heard something about it as it recently gains more popularity. Movies tend to portray artificial intelligence as robots in sci-fi and media are trying to attract attention by fancy headlines such as: “Artificial Read more…
Pasterizácia je proces tepelného spracovania tekutín (napr. víno, pivo, mlieko) na zničenie väčšiny patogénnych baktérií zahriatím na vopred stanovenú teplotu a časový interval, čo nasleduje prudké schladenie. Počas pasterizácie nedochádza ku zmene vlastností kvapaliny. Metóda vznikla v strede 19. storočia Read more…
