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. The naive classifier set a high bar. Spoiler: the support 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 until I realized that optimization of hyperparameters did not have 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 pokrok nezastavíme. Globálny nástup novej generácie IP adries verzie 6 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 simple classification algorithm, which assign a class to an item 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 argument ‘OptimizeHyperparameters’ with value ‘auto’ or ‘all’ (and also ‘none’, 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 based on its properties. We will solve this task using 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 Intelligence: The end of the human race?”, “Machines Are Getting 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 a bola pomenovaná po francúzskom chemikovi Louis Pasteur, ktorý je Read more…
Svoju prvú zahraničnú cestu v rámci môjho doktorandského štúdia som absolvoval na Katedre řídicí techniky FEL na ČVUT, v Prahe. Okrem iného som mal možnosť vidieť na akých projektoch naši českí kolegovia pracujú a aké laboratória a procesy majú k dispozícii ich študenti. Projekt Ball and Hoop je zložený z Read more…
