% Initialize weighted distance distX_initial = L2_distance_1(PX,PX); ... alpha = mean(rr);

Thanks for your question. We were inspired by the code from the work: Multi-view Clustering and Semi-supervised Classification with Adaptive Neighbours. AAAI'17 for the equation optimization procedure. We consider the alpha as a data normalization procedure which balances the scale for optimizations.
