Query: Recreation of the Periodic Table with an Unsupervised Machine Learning
  Algorithm   In 1869, the first draft of the periodic table was published by Russian
chemist Dmitri Mendeleev. In terms of data science, his achievement can be
viewed as a successful example of feature embedding based on human cognition:
chemical properties of all known elements at that time were compressed onto the
two-dimensional grid system for tabular display. In this study, we seek to
answer the question of whether machine learning can reproduce or recreate the
periodic table by using observed physicochemical properties of the elements. To
achieve this goal, we developed a periodic table generator (PTG). The PTG is an
unsupervised machine learning algorithm based on the generative topographic
mapping (GTM), which can automate the translation of high-dimensional data into
a tabular form with varying layouts on-demand. The PTG autonomously produced
various arrangements of chemical symbols, which organized a two-dimensional
array such as Mendeleev's periodic table or three-dimensional spiral table
according to the underlying periodicity in the given data. We further showed
what the PTG learned from the element data and how the element features, such
as melting point and electronegativity, are compressed to the lower-dimensional
latent spaces.
