Description
We briefly review the recently  developed tensor renormalization group method for spin and gauge models. We discuss approximate solutions of the fixed point equation for the two-dimensional Ising model. We discuss the analysis of the images of stochastically generated loop configurations (“worms”) for this model near the critical temperature, by using RG adapted machine learning  methods.  We show numerical evidence supporting the conjecture that the leading eigenvalue of the Principal Component Analysis of the worm images has a logarithmic divergence at the critical temperature. 
We discuss the correspondence between the two approaches under coarse graining procedures.
