Dataset Iris

• a base de dados dos valores das flores é composto por 3 (Íris-setosa, Íris-virgínica e Íris-versicolor) espécies diferentes com seus respectivos valores.
• o resultados de testes e treinamentos foram selecionados aleatóriamente, e foi utilizada a distância euclidiana dos elemento em teste com os elementos do treinamento, e assim foram feitas as classificações.
