Abstract
U ovome radu ćemo promatrati podatke u visokodimenzionalnim prostorima. Analiza podataka u takvim prostorima može biti računski i vremenski zahtjevna. Stoga uvodimo pojam redukcije (smanjenja) dimenzije kako bismo mogli lakše i brže provesti analizu te ćemo promatrati sljedeće metode za redukcije dimenzije: • slučajna projekcija, • analiza glavnih komponenti, • skaliranje najmanjih kvadrata. Za svaku metodu ćemo navesti prednosti i nedostatke te ćemo za metodu skaliranja najmanjih kvadrata dodatno proučiti algoritam pod nazivom "skaliranje majorizacijom komplicirane funkcije".
Abstract (english)
In this paper, we will observe data in high-dimensional spaces. Data analysis in such spaces can be a computational and time demanding. Therefore, we introduce the concept of dimensionality reduction so that we can more easily and quickly perform data analysis. We will observe the following three methods for reducing dimensions: • random projection, • principal component analysis, • least-squares scaling. For each method we will list the advantages. Additionaly, for the least-squares scaling method we will study the algorithm: scaling by majorizing a complicated function.
