Preliminary results on a way to reduce terms for text categorization are presented. We have used the transition point; a frequency which splits the words of a text into high frequency words and low frequency words. Thresholds outcoming from document frequency of terms, Information Gain and χ were tested in combination with the transition point. A text categorization experiment based on Rocchio’...

The theory of quantum phase transitions separating different phases with distinct symmetry patterns at zero temperature is one the foundations modern many-body physics. Here we demonstrate that existence a two-dimensional topological transition between higher-order insulator (HOTI) and trivial Mott same eludes this paradigm. We present critical point (QCP) driven by fluctuations percolation dom...
