  Here, we propose a novel method for representation of general spin systems
using Restricted Boltzmann Machine with Softmax Regression (SRBM) that follows
the probability distribution of the training data. SRBM training is performed
using stochastic reconfiguration method to find approximate representation of
many body wave functions. We have shown that proposed SRBM technique performs
very well and achieves the trial wave function, in a numerically more efficient
way, which is in good agreement with the theoretical prediction. We
demonstrated that the prediction of the trial wave function through SRBM
becomes more accurate as one increases the number of hidden units. We evaluated
the accuracy of our method by studying the spin-1/2 quantum systems with
softmax RBM which shows good accordance with the Exact Diagonalization(ED). We
have also compared the energies of spin chains of a few spin multiplicities($1,
3/2$ and $2$) with ED and DMRG results.
