Indeed, no tree species in the world has sparked as much interest, reverence, and awe as the Giant Sequoia (a.k.a. Visiting an old growth stand of Giant Sequoias is like walking among mighty columns supporting the cathedral of the skies.

Giant Sequoias are our planet’s most massive living things their size and majesty are awe-inspiring and utterly without equal in the plant kingdom. Among these ancient species, Giant Sequoia ( Sequoiadendron giganteum) is the undisputed king. Over the millennia, many species in the former Redwood Family have become extinct, but there remain 15 species growing today in locations from America to China to Tasmania. The only difference between the two is that regression tree doesn't enable coloring by class, but can color by class mean or standard deviation.Giant Sequoia is a member of the former Redwood Family, Taxodiaceae, a group of evergreen (and some deciduous) coniferous trees which were abundant in forests throughout the world during the mild, humid climate of the Miocene Period (about 13 million years ago). Pythagorean Tree can visualize both classification and regression trees. Save Image: save the visualization to a SVG or PNG file. Show legend: shows color legend for the plot. You can set the log factor between 1 and 10.Įnable tooltips: display node information upon hovering. Log scale factor is only enabled when logarithmic transformation is selected. Square root and Logarithmic are the respective transformations of the node size. Normal will keep node sizes correspond to the size of training data subset in the node. Size: define a method to compute the size of the square representing the node. Node color (for regression trees): node colors can correspond to mean or standard deviation of class value of the training data instances in the node. If None is selected, the color of the node will denote the most probable class. Target class (for classification trees): the intensity of the color for nodes of the tree will correspond to the probability of the target class. In our case, they are used for visualizing and exploring tree models, such as Tree. Pythagorean Trees are plane fractals that can be used to depict general tree hierarchies as presented in an article by Fabian Beck and co-authors. Selected Data: instances selected from the tree Pythagorean tree visualization for classification or regression trees.
