WebThe aim is to classify iris flowers among three species (Setosa, Versicolor, or Virginica) from sepals' and petals' length and width measurements. The iris data set contains fifty instances of each of the three species. The central goal is to design a model that makes proper classifications for new flowers. WebBasic t-SNE projections¶. t-SNE is a popular dimensionality reduction algorithm that arises from probability theory. Simply put, it projects the high-dimensional data points (sometimes with hundreds of features) into 2D/3D by inducing the projected data to have a similar distribution as the original data points by minimizing something called the KL divergence.

WebJun 21, 2024 · Figure 3: Distributions and correlations for numeric variables in iris (petal length (cm), petal width (cm), sepal length (cm) and sepal width (cm)) for the three included iris species: Iris setosa (light gray, circles); Iris versicolor (dark gray, triangles); and Iris virginica (black, squares). WebIf there is an unlabeled measurement with a petal length of 1.5 cm, it can be predicted that the species is I. setosa. However, if the petal length measurement is 5.0 cm, there is no clear prediction, as the species could be either Iris versicolor and I. virginica. Sign in to download full-size image. Figure 3.9.
