Abstract
Modeli miješanih distribucija dobro su poznat pojam u statistici u kojoj su se kroz povijest koristili za modeliranje heterogenosti populacije i generalizaciju pretpostavki distribucije. U novije vrijeme, ovi modeli također pružaju pogodan i formalan okvir za grupiranje i klasifikaciju, što su pojmovi usko vezani uz strojno učenje. Glavni cilj ovog rada je pregled modela miješanih distribucija, s posebnim naglaskom na Gaussov i Bernoullijev model miješanih distribucija. Čitatelj će biti detaljno upoznat s EM-algoritmom koji je ključan za procjenu parametara modela miješanih distribucija, a primijenit ćemo ga na spomenute Gaussove i Bernoullijeve modele te dati njegov općeniti oblik. Naposlijetku, EM-algoritam ćemo implementirati u RStudiju na raznim primjerima te analizirati dobivene rezultate.
Abstract (english)
Mixture models are a well-known concept in statistics, historically used for modeling population heterogeneity, generalizing distributional assumptions, and more recently, providing a convenient yet formal framework for clustering and classification—concepts closely tied to machine learning. The main objective of this paper is to review mixture models, with a special emphasis on the Gaussian and Bernoulli mixture models. Furthermore, the reader will be thoroughly introduced to the EM algorithm, which is crucial for estimating the parameters of mixture models. We will apply the EM algorithm to the aforementioned Gaussian and Bernoulli models and present its general form. Finally, the EM algorithm will be implemented in RStudio on various examples, and the obtained results will be analyzed.
