| Description
| - Vizualizační techniky jsou důležité v mnoha fázích dolování dat. Tento článek se zabývá především vizualizacemi pro předzpracování dat. Účelem našeho přístupu je vizualizace vzdáleností (euklidovských i jiných) mezi vzorky dat. Takováto vizualizace umožní získat přehled o shlucích, rovněž může sloužit jako vizuální detekce ustřelených vzorků. V tomto článku uvádíme vizualizační metodu která je založena na simulaci fyzikálního systém, přesněji na působení mezimolekulárních sil a minimalizaci energie takového systému. Jsou porovnány různé optimalizační algoritmy, jako: Gradientní sestup, Konjugované Gradienty i Quasi-Newtonovská metoda. Algoritmus byl původně navržen pro vizualizaci diverzity v evolučních algoritmech, v tomto článku ukážeme jeho vlastnosti při zobrazení známých databází Iris a E. coli. (cs)
- The visualization is an important technique used in many stages of data mining process. This article deals mostly with visualization for preprocessing purposes. The aim of our approach is to visualize distances (Euclidean or others) between data samples. This can be helpful when taking picture of data clustering. In classification tasks it can be used to select outlayer for removal. In this paper we present a novel way of such visualization which is based on a physical system simulation. It is inspired by intermolecular forces and employs overall energy minimization. This minimization is done via known unconstrained optimization numerical methods such as Steepest Descent, Conjugated Gradients or Quasi-Newton. The proposed algorithm was originally designed and was found useful when interpretting diversity in evolutionary algorithms. Here, we show its properties on well-known datasets Iris and Ecoli.
