In the spiral periodic classification hydrogen is placed at
Position of Helium In the spiral periodic classification helium is placed in group 2 nd. It is because of having same electronic configuration as of other elements of the second group. Also helium is similar to noble gases because it requires zero electrons to fill its outer-shell.
spirogyra | Definition, Structure, Reproduction, & Facts
Spirogyra, any member of a genus of some 400 species of free-floating green algae found in freshwater environments around the world. Named for their beautiful spiral chloroplasts, spirogyras are filamentous algae that consist of thin unbranched chains of cylindrical cells.
classification - How to classify data which is spiral in
In the post we use tree, boosting and K nearest neighbor on spiral data. KNN is most intuitive one, it make the classification according to a given point's neighbors. So, spiral data would not "break the neighbor rule" For tree and boosting model, you can understand it as a "really complicated model that can achieve complied decisions".
